摘要
针对无线传感器网络覆盖方法自身特点以及在覆盖过程中消耗大量传感器节点能量的不足,提出了一种事件驱动机制的覆盖算法。该算法通过事件驱动机制使节点之间完成了状态转换,同时建立了传感器节点与目标节点之间的关联属性,从而有效地减少节点能量的消耗,延长了网络生存周期,优化了网络资源,确保了以最少的节点完成对目标区域的完全覆盖。仿真实验结果表明,该算法中节点能量的消耗与LEACH协议相比降低了7%,验证了该算法的实效性和稳定性。
Due to the traits of WSN coverage algorithm and deficiencies of large energy consumption of sensor nodes, a coverage algo-rithm of event-driven mechanism is put forward. This algorithm established the association between sensor nodes and goal nodes by transformation of nodes realized by event-driven mechanism. Hence the energy consumption is oecreased efficiently.The lifetime of networkis prolonged and network recourses are optimized. At the same time, complete coverage of target area is achieved by the least sensor nodes. At last, the simulation experiment reflected that the energy consumption of sensor nodes is reduced 7% compared with LEACH protocol and thus the effectiveness and stability is verified.
