ENERGY EFFICIENT COST BASED ROUTING PROTOCOL FOR WSN

Sensor network is a distributed event-based system that differs from traditional communication network. Transporting information in the network with the quality of service and more efficiency is the goal. Collecting environment information is a major application of sensor network. There are many types of routing in wireless sensor network such as flat-based routing, hierarchical-based routing, location-based routing and quality of service based routing depending on the network structure. The main objective of this research is to design a routing protocol based on path cost and node weight (Energy and Delay) approach to distribute network state information to balance a load to save energy and maximize the network lifetime. The basic idea of this routing protocol is to choose a next hop node based on the optimal path cost and energy level of neighbour nodes i.e, route discovery will be processed with the higher node level energy rates and the alternate route will be chosen if any route causes failure due to the lack of load.
