COMPARATIVE STUDY OF LOAD BALANCING TECHNIQUES FOR OPTIMIZATION OF NETWORK LIFETIME IN WIRELESS SENSOR NETWORKS

In wireless sensor networks, sensors or nodes are generally battery powered devices. These nodes have limited amount of initial energy that are consumed at different rates, depending on the power level. For maximizing the lifetime of these nodes, most routing algorithm in wireless sensor networks uses the energy efficient path. These energy efficient routing algorithms select a best path for data transmission and consume less energy. But a single best path puts extra load to a specific node causing lower lifetime. The lifetime of Wireless Sensor Networks (WSN) is crucial. . In this paper, we have compared some strategies that balance the energy consumption of these nodes and ensure maximum network lifetime by balancing the load as equally as possible.
