A SYSTEM WITH LOAD SHARING TECHNIQUE VIA MOBILE NODE ROTATION FOR IMPROVING LIFETIME OF A WSN

To enhanced the lifetime of wireless sensor network various approaches have been tried. Extending network lifetime having limited power supplies is one of the big challenges facing wireless sensor networks (WSNs) due to sensor nodes. The nodes experience differential power consumption so extending wireless sensor networks lifetime is complicated. Consider the example, in a given routing topology nodes closer to the sink transmit more data hence nodes consume power more rapidly than nodes farther from the sink. To address differential power consumption and extend wireless sensor networks lifetime, new method for mobile node rotation, is using low-cost mobile sensor nodes. In proposed solution the nodes rotation take place through the high power consumption locations, and the algorithms for single and multiple rounds of rotations. The proposed solution show that mobile node rotation can extend WSN topology lifetime by more than eight times on average.
