摘要: 无线网络的入网连接时延过长,在要求快速组网的场合下应用不理想。对IEEE802.15.4无线传感器网络的协议进行了改进,NS2仿真结果证明,与原协议标准相比,分别将入网连接的两个步骤时延缩短了90%和80%左右,改进效果非常明显,使得无线网络能够应用到实时监测场合。

Abstract: Wireless networks have a long associate delay,so application in fast association occasions is not quietly ideal.This paper improves IEEE802.15.4 wireless sensor networks protocol,and NS2 simulation results demonstrate that compared with the original protocol standards,it is respectively shorten the delay by 90% and 80% in network association two steps.The effect of improvement is very obvious,and makes the wireless network be applied to real-time monitoring occasions.
