Research on routing improvement based on ZigBee

Abstract

ZigBee standard is a developing low-cost, low power consumption, short-distance wireless communication standard and routing algorithm improvement plays an important part in updating the protocol. Based on the analysis of existed ZigBee routing algorithm, this paper proposes an improvement by comprehensive using of Cluster-Tree algorithm and the "piggyback" technology to increase effective load capacity of the network, and run the simulation in NS-2, verified its feasibility. Simulation results show that the improved algorithm does not affect the other properties and reduces the number of routing control packets, so the effective load capacity has been improved. ConclusionsAiming at improving ZigBee routing algorithm, this article proposes an efficient use of the relevant parameters of Cluster-tree and relative algorithms, merging the piggyback technology commonly seen in computer network protocols, and then use NS-2 simulation platform for the validation and comparative analysis.

Reducing traffic congestion in ZigBee networks: Experimental results

“…In [6] and [7] some improvements to the Zigbee tree-based topology are proposed, by applying piggybacking technique [6] and by optimizing the number of hops to reach the destination [7]. Also [8] deals with the Zigbee tree-based topology, proposing a modification able to decrease the number of hops and to better balance energy consumption in the network, by using the information contained in neighbour tables.…”
