Coordinated node scheduling for energy conserving in large wireless sensor networks

摘要

A im ing at developing a node scheduling protocol for sensor networks with few eractive nodes, we propose a coordinated node scheduling protocol based on the presentation of a solution and its optimiza tion to determine whether a node is redundant. The proposed protocol can reduce the number of working nodes by turning offas many redundant nodes as possiblew ithout degrading the coverage and connectivity. The simulation result showsthat our protocol outperforms the peerw ith respect to the working node number and dynam ic coverage percentage.
