A Low-Overhead Hybrid Routing Algorithm for ZigBee Networks
In order to improve the non-optimal paths worked out by the ZigBee cluster-tree routing (ZTR) algorithm and to reduce the overhead of the AODVjr algorithm,we propose in this paper a low-overhead hybrid routing algorithm (LOHRA) for ZigBee networks.LOHRA effectively limits the flooding range of RREQ through utilizing the descendents of nodes and considers the length of paths and the minimum residual energy in path as routing metrics.Therefore,it not only ensures that the newly built paths are better than those of ZTR,but also reduces the redundant overhead of AODVjr and postpones the death of the nodes with low energy.Theoretical analysis and simulation results show that LOHRA outperforms the classical ZTR algorithm and AODVjr algorithm in terms of network overhead,network lifetime,and the end-to-end delay of data packets.
