摘要
野外测控场合下应用ZigBee技术对低功耗有较高的要求。在分析ZigBee路由机制的基础上,针对协议中固定发射功率,提出发射功率自寻优的改进方案,并进行仿真和实际测量。试验证明该方案可以降低功耗约30%,有效提高ZigBee网络的总体性能,具有一定的实用价值。
When the ZigBee technology is used on wild field work, it is important to reduce the energy consumption. Based on the analysis of routing process, the strategies are improved to optimize the transmitting power which is fixed in the old strategies, and make simulation and measurement. The experiment proves it can reduce the energy consumption by 30% , effectively enhances the overall performance of ZigBee network and has certain practical value.
