Power-efficient Routing in Wireless Sensor Networks

The main issue in WSN is energy limited characteristic of the sensor node. So the problem is to have the routing protocol in such the manner that it should be energy efficient in order to increase the life time of the whole WSN. Hierarchical routing architecture divides the whole network in to a group of cluster and only cluster head is responsible to forwarding the data to base station directly or via other cluster heads. In location based architecture of routing, localization of the sensor node is to be used to compute the path to the sensed data.During the creation of network topology, the process of setting up routes in WSNs is usually influenced by energy considerations, because the power consumption of a wireless link is proportional to square or even higher order of the distance between the sender and the receiver. Hierarchical routing can be centralized or noncentralized. In non-centralized hierarchical routing, the sensor nodes self-configures for the cluster head on the basis of selecting a random number. They don’t consider the case of residual energy. But in centralized routing the base station is responsible to create cluster. In hierarchical routing architecture, sensor nodes self-configure themselves for the formation of cluster heads. The proposed work is to design a routing protocol which is energy efficient and the results will be compared with other routing protocols of same category.
