Abstract

This paper presents an original approach to reduce energy consumption in an IEEE 802.15.4/ZigBee cluster tree network related to a backbone network. Our approach uses an enhanced mobility management of end devices combined with a rate adaptation algorithm. The mobility management approach anticipates link disruption and relies on a speculative algorithm that does not require scanning neighbor cells. The joint mobility management and rate adaptation methods are based on the link quality indicator (LQI). It is demonstrated that even in a noisy environment, the energy consumption as well as the latency of mobile devices can be significantly reduced.
IEEE 802.15.4/ZigBee节点联合移动性管理方法及数据速率自适应算法
本文提出了一种新颖的方法来降低与骨干网相关的IEEE 802.15.4/ZigBee集群树网络的能耗。我们的方法使用增强的终端设备移动性管理与速率自适应算法相结合。移动性管理方法预测链路中断,并依赖于不需要扫描邻居单元的推测算法。联合机动性管理和速率自适应方法是基于链路质量指标(LQI)的。实验证明,即使在嘈杂的环境中,也可以显著降低移动设备的能耗和延迟。
