Time synchronization for wireless sensor network with limited mobile nodes
Xu Wang · Jisuanji gongcheng yu sheji · 2010
To improve the time precise between the nodes in WSN(wireless sensor network) and reduce the energy consumption of the nodes,a time synchronization approach which introduces the mobile nodes is proposed.Firstly,the network with some mobile nodes is clustered and then the sender-receiver and advanced receiver-receiver models is utilized to synchronize the new network archi-tecture from different mobile nodes simultaneously.The mathematical analysis and simulation results show that it performances well in synchronization error and energy consumption of the nodes.
