Designing of Low Energy Sensor Networks by using Energy Aware Routing Protocol

Abstract

As per the system optimization in terms of speed, area and power effectively taken all the things into consideration created Low Energy Sensor Networks using Ad-hoc On Demand Distance Vector Routing Protocol(AODV).A routing protocol specifies how routers communicate with each other, disseminating information that enables them to select routes between any two nodes on a computer network. Routing algorithms determine the specific choice of route. Each router has a priori knowledge only of networks attached to it directly. WSNs have great potential for many applications in scenarios such as military target tracking and surveillance, natural disaster relief, biomedical health monitoring and hazardous environment exploration and seismic sensing. In this synopsis, we propose an energy efficient data forwarding protocol called Ad-hoc On Demand Distance Vector Routing Protocol (AODV/AOMDV) for wireless sensor networks to extend the life time of the network. Ad hoc On-Demand Distance Vector (AODV) Routing is a routing protocol for  mobile ad hoc networks  (MANETs) and other  wireless ad hoc networks . The AODV (Ad-Hoc On-Demand Distance Vector) routing protocol is a reactive routing protocol that uses some characteristics of proactive routing protocols. Routes are established on-demand, as they are needed. However, once established a route is maintained as long as it is needed. Reactive (or on-demand) routing protocols find a path between the source and the destination only when the path is needed (i.e., if there are data to be exchanged between the source and the  destination).  In AODV, both position information and energy are available at nodes used to route packets from sources to destination. The routing design of AODV is based on two parameters: location and energy levels of nodes. Each node knows the location and energy level of its neighbors. The performance measures have been analyzed with variable number of nodes. The simulations were carried out for different number of nodes.
