A Design of Zigbee Routing for Street Light Control System

Abstract

Zigbee is a non-infrastructural wireless network which has low data rate and self-reconstruct capacity. There are two routing algorithms for Zigbee mesh network : Tree routing and On Demand routing. This paper attempts to using On Demand routing protocol to construct the data transfer path in symmetric street light structure. Like AODV(Ad-hoc On-demand Distance vector), we must reduce control message to find the route in limited bandwidth network. This paper proposes AODV-BN (Backup Node) according to AODV-BR. AODV-BN only use RREP message to find the back up node and get the neighbor table by eavesdropping instead of sending Hello Message. So we can use very small amount of control messages to fix the broken route and reduce the collision. Finally, this paper use NS-2 (Network Simulation) to simulate the performance of AODV-BN. The simulation results present that our methods reduce the control message indeed and improve the throughput of the network.
