Adaptive and Energy Efficient Data Gathering Using Sink Relocation

A Wireless Sensor Networks (WSNs) consists of small-sized sensor devices, which are furnished with limited battery power. In this paper, an energy efficient routing protocol and sink relocation mechanism is proposed, which is to increase the lifetime of sensor node and also increase the performance. Sensor nodes which are present near the sink, will generally consume more battery power than other sensor nodes and this will become one of the major problem. Sink relocation is an extension method for efficient network lifetime and avoids too much energy consuming for a specific group of sensor nodes. Energy-aware multiple sink relocation (EAMSR) is proposed for moving strategy of mobile sinks in WSNs. This method is used to reduce the energy consumption of nodes. This approach uses data delivery latency. The regular network operation are relocating the sink is very challenging. The proposed methodology is using the information which is related to the residual battery of sensor nodes to adjust the transmission range of sensor nodes.
