[attachment=60223]
Abstract-:
Wireless sensor network consists of
thousands of individual nodes which collectively
work as per application of the network. Each node
made up of various parts which individually having a
big research area. One of the upcoming research
area of it is its power consumption which in turn
depends on energy wastage of nodes. So various
steps are to be taken to overcome this problem of
energy wastage, one of them would be the proper
designing of routing algorithm that considers the
factor that enhances energy wastage. In this paper
firstly outline of WSN is being discussed which
includes MAC and routing protocols of WSN , then
an optimised routing protocol is proposed and its
analysis is done by MATLAB simulation tool. Finally
paper is concluded and its future scope is being
discussed.
INTRODUCTION
The concept of wireless sensor networks [1, 2] is
based on a simple equation: Sensing + CPU +
Radio = Thousands of potential applications.
Wireless sensor networks [3] consist of multiple
sensor nodes exchanging data per wireless
connection. Each sensor node can collect process
and transfer local environmental information. This
opens a wide range of applications, not only in the
military field, but also in environment and habitat
monitoring, healthcare systems, home automation,
traffic control, and early disaster detections. The
major factor that influences the sensor network
design is lifetime of node which can be enhanced
by making an energy efficient routing algorithm.
Section 2 gives the idea about MAC protocols and
routing protocols in wireless sensor network and
gives overview of various existing protocols. In
Section 3 a new routing algorithm is being
proposed which considers the factors that leads to
energy wastage and also the algorithm is
optimized in sense of distance travelled.
MAC AND ROUTING PROTOCOLS IN
WIRELESS SENSOR NETWORK
Medium Access Control (MAC) protocols [4, 5]
coordinate the times where a number of nodes
access a shared communication medium. MAC
protocol task is to regulate the access of a number
of nodes to a shared medium in such a way that
certain
application-dependent
performance
requirements are satisfied or in other words it
specify how nodes in a network access the shared
communication channel. MAC protocols can be
classified as: whether the protocol is Fixed
assignment, Demand assignment and random
access based. Second is on the basis of which
problem of energy wastage is being solved by the
protocol. Another classification is whether the
protocol is contention based or scheduled based.
Various MAC protocols are [9-11]:
RESULTS AND ANALYSIS
The proposed routing algorithm is being simulated
in MATLAB. The GUI designed consists of number
of nodes and sink node, both of these are user
defined. It also contains pushbuttons topology and
routing described below. It also gives the path
followed by data from source to sink via
intermediate nodes with low energy consumption
and shortest path. The axis shows the deployment
of nodes in network and routing path from source
to sink. Nodes with red colour shows sink node,
green colour is for source node and magenta
colour for intermediate node.
CONCLUSION AND FUTURE SCOPE
Routing in sensor networks is a new area of
research, with a limited, but rapidly growing set of
research results. This thesis work design an
energy efficient optimized routing algorithm that
combines the features of both an energy efficient
routing algorithm and shortest distance routing
algorithm thus the main factor that effect the
proper working of Wireless Sensor Network i.e
lifetime of WSN nodes has been reduced. Since
the energy consumption reduces and distance is
also optimized so the proposed routing algorithm is
cost effective.
