ZigBee是一种基于IEEE 802.15.4标准的最新无线网络技术，专为低数据速率和低占空比应用（如家庭和楼宇自动化以及传感器网络）而设计。ZigBee的主要目标之一是低功耗，因此是长寿命网络。尽管有这个目标，ZigBee规范中描述的当前网络形成和路由协议并没有完全解决功耗问题。在这项工作中，我们提出了一种分布式路由算法，以减少电池供电的设备的功耗路由通信通过电源供电的设备，只要有可能，从而增加整体网络的生命周期。该算法适用于ZigBee支持的树拓扑结构，只需要对当前规范进行微小的修改。我们的ns-2仿真结果表明，该算法能够以最小的通信开销显着降低电池供电设备的功耗。
ZigBee is a recent wireless networking technology built on IEEE 802.15.4 standard and designed especially for low-data rate and low-duty cycle applications such as home and building automation and sensor networks. One of the primary goals of ZigBee is low power consumption and therefore long-living networks. Despite this goal, current network formation and routing protocols described in the ZigBee specification do not fully address power consumption issues. In this work, we propose a distributed routing algorithm to reduce power consumption of battery-powered devices by routing the communication through mains-powered devices whenever possible and consequently increasing the overall network lifetime. The proposed algorithm works on tree topologies supported by ZigBee and requires only minor modifications to the current specification. Our ns-2 simulation results showed that the algorithm is able to reduce the power consumption of battery-powered devices significantly with minimal communication overhead.
