摘要
针对无线传感器网络中各传感器节点电源能量和通信能力有限的问题,给出一种基于优化LEACH算法的超高层构筑物智能监测系统的应用方案。硬件系统采用双处理器结构,具有较高的数据处理性能和低功耗特性,网络使用间接轮询的ZigBee协议实现数据传输,避免了电池的快速消耗,从而降低了系统的能耗。仿真结果表明,使用优化LEACH算法时,第一个节点死亡的轮数较LEACH算法提高了19.5%,节点平均能耗减少了10%,有效地提高了网络的生命周期且具有较好的抗毁性。
According to the limited power energy and communication capability of each sensor node in wireless sensor networks,an application scheme of optimized LEACH algorithm based intelligent monitoring system for super high-rise structures is given.The hardware system adopts the dual-processor structure,which has high data processing performance and low-power consumption characteristic.The ZigBee protocol with indirect polling is used in network for data transmission,which can avoid the rapid consumption of the battery,and reduce the system′s energy consumption.The simulation results show that,in comparison with LEACH algorithm,the round number of the first died node is increased by19.5%,and the average energy consumption of the node is reduced by10%by using the optimized LEACH algorithm,the scheme can improve the life cycle of the network effectively,and has strong invulnerability.
