An energy efficient for WSN using mobile co-ordinator in fuzzy method

Abstract

Wireless sensor networks are used in many real-time applications. In WSN, effective use of energy resource is one of the challenging research issues as the battery limits the lifetime of sensor node. The Rumor Routing has advantages in energy saving by making full use of two features: clustering structure and next-hop scheme. This rumor routing algorithm in WSN allows query source to distribute query to identify source which helps to get timely query message but the energy efficiency is made better using hierarchical method by clustering formation, where the appropriate selection of cluster head reduces energy conservation. So we have fuzzy logic as the proposed method which is based on three features : Centrality, Energy, Distance. The mobile co-ordinator is used in this method to increase the network efficiency. Thus fuzzy logic can effectively avoid the problems that occur in RR and can provide more energy-efficient routing paths. The performance between fuzzy logic using mobile co-ordinator and RR are evaluated by simulations. This simulation results indicate that compared with RR, the fuzzy logic can save energy consumption, provide better path, and increases delivery rate.
