– At present waste
management is a major concern in the metropolitan cities of the developing and
developed countries. As the population is growing, the garbage is also
increasing day by day. Garbage management is
becoming a global problem. Due to the lack of care and
attention by the
authorities the garbage bins are mostly seem to be overflowing It has to be
taken into care by corresponding authorities and should think what method can
be followed to overcome this. This
huge unmanaged accumulation of garbage is polluting the environment, spoiling
the beauty of the area and also leading to the health hazard. To overcome this
situation an efficient smart municipal waste management system has to be
developed. In this era of Internet, Internet of Things (IOT) can be used
effectively to manage this waste as many effective methods can be found out
easily. This is the survey paper which involves the various ideas to solve this
problem using some algorithms that can be easily implemented.
Key Words: Internet of things (IOT), Smart
smart cities represents hot topic in terms of improving living conditions. As one of the application of Smart City, Waste
Management in a city is a formidable challenge faced by the public
IoT is a network of sensors where data is
exchanged, using different connectivity protocols, with systems.
Waste is defined as any material in which something valuable is not
being used or is not usable and represents no economic value to its owner, the
waste generator. Depending on the physical state of the waste, they are
categorized as solid waste and wet waste. With the proliferation of population,
the scenario of cleanliness with respect to waste management has become
crucial. Waste management includes planning, collection, transport, treatment,
recycle and disposal of waste together with monitoring and regulation. The
existing waste management system, where the garbage is collected from the
streets, houses and other establishments on quotidian basis, is not able to
effectively manage the waste generated. Our work focuses on the
optimization algorithms for Smart City management and more specifically this
paper deals with municipal waste collection procedure. Nowadays,
the garbage-truck needs to pick-up all garbage cans even if they are empty. To
avoid such challenges faced we are proposing a system where efficient routes
are defined shortest route to collect the garbage filled bins.
The garbage management
in cities should be effectively and efficiently implemented. The various
proposals were put forward and some of them are already implemented. But we cannot considered it as an effective one.
So a survey was done among different proposals and this survey paper includes
survey among different methods for smart garbage management in cities using
IoT. This section discusses
about the existing approaches in the field of smart waste management.
Insung Hong et.al 1 has suggested that
replacing SGS(Smart Garbage Sensor) instead of RFID garbage collecting system
helps to improve their energy efficiency up to 16% and can reduce the food
waste reduction .Inside the SGS they have installed SGBs (Smart Garbage Bins)
to control the energy efficiency of the system.
Dario Bonino et.al 2 has suggested that it
provides end – to – end security and privacy that is built upon dynamic
federation smart city platform. Its benefits is that it has good dependability
and has resilience on failure of a system over a particular month. It focuses
on the collection of wastages and accomplishment of ontology method.
A lvaro Lozano Murciegoet.al 3 has
suggested that to collect the dustbins that are been filled using a truck. The main
advantage is that it reduces the fuel cost of the trucks rather than travelling
a long distance it makes the path more simple and easier to reach the dustbin
using route optimization.
TheodorosAnagnostopoulos et.al 4 has
suggested that it first starts with an assumption that the smart city must
include the IoT base. It uses dynamic scheduling. It is based on the fact that
the garbage will be collected only when it is fully filled or the maximum
capacities of the dustbins are filled.
Rachael E. Marshall et.al 5 outlines that
the smart waste management system in the high salaried countries and an
Lilliana Abarca Guerrero et.al 6 outlines
the fact that the developing countries undergo an prominent factor of affecting
the waste management systems due to rising population levels and rapidly
growing urbanization. The collaborator of the waste management are many such as
household, industry sectors, educational and research intuitions etc produces
huge number of wastages. Collecting, transferring, Transportation of the wastages
and they are finally disposed in an open land.
Ala Al – Fuqaha et.al 7 proposed that
sketch of the IoT with a stress on technology, application and protocol
concern. It explains about the differences between IoT and developing
technologies like cloud computing and data analytics.
Jose M. Gutierrez et.al 8 proposed the
functional smart city and the use of an smart waste management .It uses IoT for
sensing the wastage level in the dustbins, processes the data and sends it to
the server for storing and process the data. The process is carried out by the
Geographical Information system.
Vikrant Bhor et.al 9 has suggested that
when the system ensures that the garbage bins are fully filled up to their
maximum it must be cleaned using IR sensor, GSM mode and microcontroller. When
it is not filled it must be reported to the higher authority of a particular contractor.
It concludes that it has a clean environment and it decreases the total number
of trips the garbage collector vehicle rounds.
Fachmin Folianto et.al 10 has suggested
that it uses mesh network. It is used to produce data and deliver it to the
mesh network. Whenever the bins are filled they need to be cleaned. The bin
collector gives the route to collect the bins.
In 11-14, the routing protocols and the
failure detection in sensor nodes are discussed.
2.1 RECENT RESEARCH IN MUNICIPAL WASTE COLLECTION
The constant growth of
population urban areas brings increasing municipal solid waste generation with
socio-economic and environmental impact. Municipal solid waste management –
source separation, storage, collection, transfer and transportation, processing
and recovery, and last but not least, disposal, are today current city
challenges. The mathematical programming and processes have been already used
for optimizing the municipal waste management and transfer system. The waste collection
and garbage-truck allocation problem could be solved by traditional
mathematical methods such a linear methods. However, the linear methods show
insufficient efficiency in some more difficult cases of waste collection. The
large amount of variables was the reason for large computation time. The recent
research works use mostly the heuristic solutions and methods dealing with the
municipal waste collection as with a Travelling Salesman Problem (TSP). Dealing
with problem formulation, the effectiveness of optimization and computation is
based on input parameters and specific problem implementation. Only few works
tried to use evolutionary algorithm to deal with implementation and
optimization of waste collection problem as the TSP defines. These works use
Ant Colony algorithm. However, the genetic algorithm was also proven as a very effective
tool to deal with TSP of various implementations, but not in the specific
implementation of waste collection 4.
faced while working with wireless sensor networks (WSN)
Energy – Sensors require power for various operations.
Energy is consumed in data collection, data method, and
data communication. Batteries providing power
need to be changed or recharged once they have been consumed. Sometimes it
becomes powerful to recharge or change the batteries as a result of demographic
conditions. The most
critical research challenge for the WSN
analysts is to design,
develop and implement energy adequate hardware
and software protocols for WSNs.
2. Self-management – Once
when WSN are deployed it should be capable of working without help of human
3. Security – Confidentiality
is required while data transmission otherwise there is possibility of eavesdropping
Quality of Service – Quality of service is the level of service
provided by the sensor networks to its users. WSN are being used in various
real time applications, so it is mandatory for the network providers to offer sensible
Tolerance – Sensor network should be able to work even if any node fails whereas the
Network is operational. Network should be in a position to adapt by changing its
property in case of any difficulty.
Limited Memory and Storage Space – A sensor is a small device
with low quantity of memory and storage
space for the code. In order to make an effective security mechanism, it is
necessary to limit the code size of the security algorithm.

Freshness – There should be fresh message even if confidentiality is
assured. Informally, knowledge freshness suggests that the data is recent, new
and it ensures that no old messages have been replayed. To solve this problem
another time – related counter, can be other into the packet to make sure
Localization – Often, the utility of a device network can trust on its
ability to accurately mechanically find every sensor within the network. A
sensor network designed to find fault scan would like correct location data in
order to purpose the placement of a fault.
· Privacy – The sensor networks have conjointly force privacy issues.
Initially the sensing element networks area unit deployed for legitimate
purpose may later on be used in out of the blue ways that. Providing awareness
of the presence of sensor nodes and knowledge acquisition is notably vital.
routing – Routing and data
forwarding is a crucial service for facultative communication in device
Availability – Availability resolves whether or not a node has the capacity
to use the resources and whether or not the network is obtainable for the
messages to speak. However, failure of the base station or cluster leader’s
availability can eventually threaten the complete sensing element network.
Thus availableness is of primary importance
for maintaining associate degree operational network
The route planning and optimization is a well-researched area and
hundreds of intelligent transport systems have been developed already. There
are many projects aiming to provide an effective system for waste collection
purposes. In 7 an advanced routing and scheduling waste collection model is
proposed in eastern Finland, in which they use the guided variable neighbourhood
thresholding Meta heuristic. A geographical information system transportation
model for the solid waste collection and disposal is another technique. A truck
scheduling model for the solid waste collection has been proposed by the city
of Porto Alegre in Brazil. The aim of the research was to develop an optimal schedule
for the trucks on defined collection routes. In 8 a novel cloud based approach
is being employed. On board surveillance cameras for problem reporting with a
cloud DSS system and dynamic routing models are used and this significantly
increases the cost effectiveness, which is one of the important criteria of the
mart cities. A method is proposed to use the operations research techniques to
optimize the routes of waste collection vehicles servicing dumpster or skip type
container. Here the waste collection problem is reduced to classic TSP then to Concorde
solve the problem. The system aims to minimize the distance travelled and
thereby helps in the reduction of vehicle wear. A new method for optimizing the
waste collection routes is developed based on OSGeo software tools.

3.1 ALGORITHMS USED
Algorithms used in previous
papers for research work was done.
3.1.1 XML Parsing used for graph processing –
The XML parsing is used for
the graph (SVG) processing. After XML parsing.
3.1.2 Floyd- Warshall algorithm
The Floyd- Warshall
algorithm is applied to distance recalculation. This algorithm was chosen due
to the fact that we are using metric system and there the negative values of
edges are not used. The algorithm (Floyd-Warshall) also computes straight the
vertices distance, which is less time consuming than i.e. Dijkstra Algorithm
(which computes distances always for each vertex).
4. DIFFERENT APPROACHES
Fig -1: System Overview
There are some different
approaches in paper 9 the proposed system was based on waste data level of
garbage bins in metropolitan areas. The data was sent over the internet for analyzing
and processing. Everyday new data was collected and on that basis the rate of
waste level was calculated so as to predict the overflow of bins before. Fig 1.
Gives the overview of this approach.
Another approach paper 12
was the bins were kept overall anywhere in the city or areas, a low cost device
was inserted in the bin and a unique ID was assign to every garbage bin to
check which bin is full. There were 2 parts Transmitter and receiver sections,
sensors, 8051 microcontroller in which data from sensor was processed and send
to central system by RF Transmitter
method 13 was when the garbage reaches a threshold level ultrasonic sensor
will trigger GSM module to give alert till the trash can is empty. In this GSM
900 A modem was used to send the messages The ultrasonic sensor also calculated
the height of the trash can at regular interval. There 3 sensors at
various heights like h/3, 2h/3 and h, where h is the height of the bin but to make
it affordable and to get the results.
This survey has been performed for collecting
the details of smart garbage management methods and to find out effective
methods which are useful for providing hygiene environment in cities. Our
solution is based on the idea of IoT infrastructure, which should provide
enough information to handle this Smart City issue more efficiently.
