Dynamic Wireless Sensor Network parameters optimization adapting different node mobility

Topology change is the main factor which is affecting the network life time of Wireless Sensor Network applications. In normal WSNs with stationary nodes, the topology change is often caused by node failure which is due to energy depletion. However, in the mobile Wireless Senor Network, the main reason of the topology change is caused by the node movement. Sensor nodes in the network may move in any patterns, and different mobility patterns have various influences on the network life time. In this paper, through extensive simulations on different routing protocols with different mobility patterns, we evaluated the impact first, and then analyzed the reasons, in the end we proposed a dynamic parameters optimization method for the mobile Wireless Sensor Network.
