摘要
针对计量自动化系统中无线传感器网络存在的数据传输效率不高、节点的数据传输拥塞严重的问题,提出一种优化路由算法。该算法基于传输效率和拥塞控制平衡考虑的思路,通过对链路效率和流动半径的融合计算,实现了节点数据路由能够合理选择多跳路径,从而确保无线网络的链路资源得到充分利用,节点拥塞程度得到降低,数据通信速率得到提高。通过实验证明,该算法能够在可以接受的时延基础上有效降低网络的丢包率,保持网络的数据传输效率。
In this paper,an optimal routing algorithm is proposed for the problem of low data transmission efficiency of wireless sensor network in metering automation system and the serious problem of data transmission congestion in nodes.Algorithm was based on the transmission efficiency and congestion control balance,efficiency and flow through the link radius calculation of fusion,has realized the data routing nodes to select reasonable multiple hops path to ensure full use of the wireless network link resources,in order to reduce the node congestion and improve the data communication rate.The experiment proves that the algorithm can effectively reduce packet loss rate and maintain network data transmission efficiency on the basis of acceptable delay.
