Abstract

ZigBee is a networking standard for low power, low data-rate, resource constrained networks. It provides network and upper layer services for LR-WPAN, cyber physical systems, industrial sensor networks, smart grids, home automations, etc. The routing layer uses the tree based routing protocol wherein only parent-child relationship are considered for routing, ignoring neighbor nodes. This results in packets being routed through several hops towards the destination even if it is within senders 1-hop transmission range, via highly loaded or high traffic links. The paper proposes an improved ZigBee algorithm by employing neighbor tables and link quality indicator (LQI). Keeping in mind the low complexity of traditional ZigBee protocol, priority based approach has been implemented by using two reserved bits as priority bits in route selection. Opnet Simulator is used for the simulation purpose along with Visual Studio 2005 for C++ compiler. From the simulation results it can be observed that the proposed priority based routing protocol performs better than the classical ZigBee tree algorithm, and thus can be claimed as an enhanced ZigBee protocol.

基于优先级的ZigBee LR-WPAN路由协议

ZigBee是一种针对低功耗、低数据速率、资源受限网络的网络标准。它为LR-WPAN、网络物理系统、工业传感器网络、智能电网、家庭自动化等提供网络和上层服务。路由层采用基于树的路由协议，路由只考虑父子关系，忽略邻居节点。这导致数据包经过几个跳路由到目的地，即使它在发送方的1跳传输范围内，通过高负载或高流量链路。提出了一种采用邻居表和链路质量指标(LQI)的改进ZigBee算法。考虑到传统ZigBee协议的低复杂度，基于优先级的方法在路由选择中使用两个预留位作为优先级位。Opnet模拟器与Visual Studio 2005的c++编译器一起用于模拟目的。仿真结果表明，所提出的基于优先级的路由协议性能优于经典的ZigBee树算法，是一种增强的ZigBee协议。
