Abstract:Data collection is the fundamental purpose of deploying Wireless Sensor Networks(WSNs). The adoption of mobile accommodation strategy can effectively alleviate the problem of energy consumption of WSNs. The mobile path is the key of the strategy. Therefore, Virtual Rendezvous points -based Data Collecting(VRDC) algorithm is proposed in this paper. The VRDC algorithm first plans lodging paths based on the host Points, and then selects Virtual Rendezvous Points(VRPs) based on the host Points. VRPs can transmit data directly to the mobile address via one hop, while other nodes can transmit data to the nearest VRPs, thereby reducing the number of transmission hops and energy consumption. Simulation results show that VRDC algorithm can effectively reduce energy consumption and balance energy consumption among nodes.
