Topology control method using adaptive redundant transmission range in mobile wireless sensor network

In this paper, we simulate the effect of RTR (Redundant Transmission Range) which is used to maintain network connectivity in mobile wireless networks such as ad-hoc or sensor networks. The simulation result shows that the RTR scheme greatly increases network connectivity time. Based on the simulation result, we propose an A-RTR (Adaptive-RTR) algorithm. A-RTR use variable RTR as node's moving speed and neighbors' speed. This algorithm can be used any topology control algorithms and prolong the network connectivity time in mobility environment. Simulation results show good performance not only the network connectivity but also node's energy consumption
