It is well-known that localization in Wireless Sensor Networks (WSNs) is costly. However, after deploying and localizing the sensors, sensors may be moved from their original location by the depredation of the enemy or natural phenomena. In such cases, moved sensors return the inconsistent information with their incorrect location to sink or spread the incorrect location to the network resulted in...
Time synchronization is important for many applications running in wireless sensor network. A classical algorithm, Timing-Sync Protocol for Sensor Networks (TPSN), has been widely adopted, which can achieve of the goal of high accuracy and energy-efficiency. However, the accuracy of TPSN algorithm will decrease in practical environments since communication conflicts occur in an ad-hoc wireless environment...
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...
