Fuzzy Link Cost Measure for Energy Efficient Routing in WSN

Wireless Sensor network (WSN) is being widely used in various application but limited energy of remotely deployed sensor nodes remains area of concern. This concern had made energy efficient routing as a key parameter of WSN and various approaches had been used. In my earlier work of an Adaptive Energy Saving and Reliable Routing Protocol(AESRRP) combined link weights is determined based on the parameters node's residual energy and transmission parameters. Best Route selections were made based on link weight cost (crisp). In this paper fuzzy logic approach is used to calculate link cost between two adjacent nodes. Three parameters residual energy of sensor nodes, distance of cluster head to sink and density of nodes in a cluster are considered.
