ZigBee网络路径均衡算法在供水系统的仿真研究

Research and Simulate of ZigBee Network Path Equilibrium Algorithm Applied in the Water Supply System

研究城市供水系统的高效路径均衡算法。供水系统根据供水请求调控供水路径,在早晚城市用水高峰期供水请求突增,待均衡的供水路径任务骤增加大了均衡计算量,传统方法只选用较少的高层节点作为均衡节点,高层节点因超额的工作量不能承担起均衡任务的突增,造成网络数据传输路径均衡的效率较低。为了解决这一难题,提出基于开销能量的供水系统ZigBee网络路径均衡算法。通过建立供水系统各节点能量消耗代价开销模型,在模型中根据开销能量将路径均衡控制的任务分派到网络的各个节点中共同分担完成路径均衡的任务,避免了只利用少数高层节点均衡而带来的均衡效率不高的问题。仿真结果表明,改进方法能够高效完成供水系统路径的均衡控制,取得了满意的结果。

Research the efficient paths equalization algorithm of urban water supply system. Water supply system according to the water supply control request water supply path. In the morning and evening rush hour of urban water supply at the request, the balance of water supply to keep the equilibrium path task more calculation. The traditional method using only less top node as an equilibrium node, because of the extra workload top node unable to undertake this task equilibrium increase, causing network data transmission path balance of low efficiency. In order to solve this problem, this paper put forward a path equalization algorithm based on ZigBee network the cost of the energy of the water supply system. Through the establishment of the water supply system each node energy cost price cost model, according to the path of energy assigned balance control task to each node in the network that share the complete path balanced task, avoiding using only a few the top node equilibrium and brings balance the efficiency is not high. The simulation results show that the improved method can finish high efficiency water supply system of the path the bal- ance control, and satisfactory results were obtained.
