In dynamic insensitive application specific network, WSN consists of hundred and thousands of sensor nodes densely deployed in the sensor field. Majority of sensor nodes are static having power limitations, low network throughput, message transfer delays and computation power limits that are major obstacles. The limited communication range of WSN nodes, link asymmetry, and the characteristics of the physical environment lead to a major sources of QoS degradation in WSNs. The potential applications of the WSNs typically range from those in defense, military, environmental monitoring, health monitoring and civilian surveillance applications etc.
