Wireless Sensor Network (WSN) is a group of number of sensor nodes. Nodes are spatially distributed to monitor physical and environmental conditions. Multi-hop communication is significantly predictable in WSN, because of limited transmission range and energy saving purpose. Traffic load in multi-hop wireless sensor network is not distributed uniformly over the nodes; hence energy consumption is different at different levels. This unfairness reduces network lifetime. To maximize the network lifetime, it is important to adjust resources according to their utilization at particular point.
