Abstract: Wireless Sensor Networks (WSN) and IOT has become a prominent field of study
for the researchers because of its extensive application over various field. A possibility for the smart cities and Smart home system is possible now. The main function of any smart product application is how they communicate with each other. For this purpose many routing protocols have been devised to minimise the different over head of the system like energy, cost, distance etc. Routing for different wireless sensor applications based on parameters is smooth and dependent solution resulting in low information costs for the network package, as well as for the node itself. This project introduces the kind of protocol for using a different neighbours node and different parameter which are associated with them like distance, energy, cost etc. The key point of this paper is to present with a solution which could let a user control for example the lighting system of the whole town from one place. In this paper, we present the implementation details of the porting of the linear hopping protocol to the discrete event network simulator NS3.We develop this module for NS3 to simulate the performance, multi node execution, and multi node configuration using nrf24 and atmega328 Arduino.

1. INTRODUCTION
This work is part of the project that analyzes the development of technologies for wireless
system network, these monitors and controls different variables. If we take an example of the
wireless lighting system ,here the system consists of devices attached to the lighting points,
which are interconnected via network, and software tools used for monitor and control. More
specifically, this work researches and analyses the implementation of efficient network
routing protocols according to the requirements of not only a street lighting application but on Journal homepage: www.mjret.in
a broder prespective can be implemented on any wireless system. The discussed protocols
in this paper requires to send the packet to the different node and wait for the ack signal.
Once it has received the acknowledgement signal it send the packet with along with the
node id attach with the packet to identify which node has send the data. In case due to some
external or internal factor the neighbour node stops working , either it stop the transmission
or the ack signal is lost then the previous node send the data to next of its neighbour node .It
does not wait for the faulty node to get repair or wait for the any node to get free so that it
can send the data packet. The method which exist now a days are that either they wait for
the channel to get free and always continuously sends signal to check or wait for the node to
get free. These methods either take a lot of time or is not cost effective , or it uses a lot of
manual labour which is not required in the smart cities.
This work centers on a routing solution for different smart system, and overhead packet
distribution in a large scale scenario of WSN. The presented work is a research and
development project for the development of different routing protocol for large scale
networks, which solves two main problems . Work developed so far is to considers that in
order to make it successful transmission of packets it has to know to which node the data is
being send. As there is linear communication of the nodes so there is no need for the
message to be copied over and over again and there is no need to implement complex
algorithm like CSMA/CA or CSMA/CD.
Researchers from this area agree that point-to-point message confirmation is essential to
WSN, that is, the node must acknowledge that the message sent was received. It will help
the base station to know the faulty node if there is no acknowledgement or if there no
transmission of data.

EXISTING METHODS
The existing method which are in effect are either ineffective or are very costly. The
multi-hopping used in the big cities are they broadcast their network and wait for a response from
the nodes which are free. In case there are multiple node which are available then it selects
which is the nearest channel and sends the packet. This creates a number of redundant data
which increases the overall size of the packets in the database
The second method which is most common these days are the spread spectrum .In this the
channel the node wait for the channel to be free and then sends the packets This increases
the complexity of the system and reduces the transmission rate as it increases the wait up
Based on the RFC 5548 [1], the list below briefly defines the non-functional
requirements:
Lifetime: sensor nodes depend on batteries. However, for this project, sensor nodes
are powered by energy cables that are already used in current street lighting
structures;
Latency: acceptable latency should be on a time interval in the order of tens of
seconds
Fault tolerance: the routing algorithm proposed in this work must be fault-tolerant
because the messages must find a reliable path to reach the destination;
Scalability: it is important to consider that the project should apply to small (up to 25
nodes), medium (25 to 103 nodes) or large networks (102 to 107 nodes).

3. PROPOSED SYSTEM
Our system aims at the linear hopping communication between different nodes .In this
project the nodes are placed at different location and the given a order in which they will
route the data. Here the first node will send a Request signal to the second node for the
transmission of data. If the second node is ready to receive then it send back the ack signal
In case the second node is fails to establish the connection due to some internal factor or the
external the first node sends the request packet to the next neighbour of the failure node and
that node then sends back the ack signal to the first node and then starts the
communication. The minimum operating distance between each node should be atleast 30m
and it should always works in a set of defined frequency so as to avoid any collision with
other wireless transmission.

5. FUTURE SCOPE
The possibility of the proposed system is numerous as it can not only be implemented on the
street light but can also be used to control the traffic system. It can be used to improve the
existing GPS system by providing a better overview of the nearby heavy traffic area and
many more. Let us take the example of the street light system.
Previously if some street light pole was not working or was damaged then we would not get
to know about it, but by using this implementation it will help us to know whether a light pole
is working or not and it will also give us the location in which the light pole is situated.
All the operations and other functions can be done only through base station which will
reduce a lot of extra work. Through this manual work will be reduced as the person need not
go and check whether the pole is working or not. It is cost effective, will save the energy for
future generations, operating through one station all these advantages is be achieved.
6. CONCLUSION
Our proposed system can be stated to be cost effective, practical, eco-friendly and the safest
way to save energy and in this system the light status information can be accessed from
anytime and anywhere.
It clearly tackles the two problems that world is facing today, saving of energy and also
disposal of incandescent lamps, very efficiently.
