ZigBee Routing Selection Strategy Based on Data Services and Energy-Balanced ZigBee Routing

A mixed routing strategy of AODV and tree routing is designed in the ZigBee specification. But there is no method designed to balance these two routing modes in order to achieve better performance. We realized the ZigBee protocol module in NS2. Simulations had been run to analyze the ZigBee network performance. According to the analysis, a strategy of ZigBee routing selection based on data services has been proposed. The simulation results show that such routing selection strategy has excellent network performance and low energy consumption. Additionally, the power control is not much considered in ZigBee routing specification. But for the ad hoc wireless network application, power control is the most significant issue in ZigBee. So a power control strategy is proposed to improve the ZigBee routing, the simulation results show that this power control strategy will greatly balance the node energy, avoid that nodes use up all the battery power and die too early
