摘要: 针对灾害感知网络的特点,提出一种在保障网络可靠性前提下降低网络能量消耗的拓扑控制方法。将监测域划分为若干拥有合适半径的感知网格,以减少节点信息的传输距离。采用合理的休眠机制,以减少感知网络的能量消耗。仿真结果表明,应用于灾害感知等任务型网络时,该方法可有效降低网络的能量消耗,延长网络的使用寿命。

Abstract: According to the characteristics of disaster awareness network, this paper proposes a method to reduce network energy consumption under security network reliability. The monitor domain is divided into several sensor grids which have appropriate radius, so as to reduce the transmission distance of the node information. It adopts reasonable dormancy mechanism to reduce the perception of network energy consumption. Simulation results show that this method can effectively reduce the network energy consumption and prolong the network life when it is applied in the tasks network such as disaster awareness.

Key words: Wireless Sensor Network(WSN), sensor grid, topology control, reliability, energy consumption, sleeping
