Joint Sink Mobility and Node Deployment for Prolonging Lifetime in Wireless Sensor Network
Huiyong Yuan · 2015
When cluster heads transmit their data to the sink via multi-hop mode, the cluster heads closer to the sink are burdened with heavy relay traffic and tend to die early.In this paper, taking both sink mobility and node deployment into account, we investigate the energy-hole problem of data gathering in wireless sensor networks, and propose a new node deployment strategy for multi-hop wireless sensor networks with mobile sink.Simulation experiments show that the proposed strategy can effectively balance the sensors energy consumption and prolong the network lifetime.
