Energy Efficient Routing Protocol for Wireless Sensor Networks with Multiple Sinks

Wireless sensor network is a network of self-directed tiny sensor devices. Sensor nodes collect data from their surrounding environment and send these data to sink for post data analysis. The current popular application domains of sensor networks are environment, health, home, military, security and commercial areas. In this paper we have proposed an energy efficient routing protocol for wireless sensor network with multiple sinks. This proposed protocol ERPWSN works on the concept of optimal energy consumption. The ERPWSN has four phases as Updating Information, Selection of Cluster Head, Labeling and Data Routing. The cluster formation based on energy of sensor nodes and path switching. The CH forwards collected data to the sink which is at minimum distance from CH. If two sinks are at same distance then we consider energy of sinks. We have compared this proposed protocol ERPWSN with the standard routing algorithm LEACH and Multi Sink routing algorithm ERMSS. In the simulation result, it states that our proposed protocol has better performance.
