Abstract

ZigBee hierarchical routing protocol (HRP) provides a simple but reliable topology. However, the transmission paths in HRP are always not efficient, and the links keep invariant since they were determined when the network initialized. In this paper, we propose and evaluate a real time routing optimization scheme in ZigBee hierarchical networks. In the improved architecture, the parent node could actively maintain its child links for lower network load. To minimize the energy consumption, all the information needed can be acquired from neighbour table to avoid introducing extra communication. The scheme makes ZigBee hierarchical networks be capable of dynamic maintaining and optimizing the routing paths during lifetime. The simulation results show that the proposing scheme have better performance by obtaining lower average transmission hops and network load.
