摘要
针对无线短波自组网传输信道的特殊性,通过分析链路质量和节点业务负载对路由性能的影响,提出了一种基于路径质量和网络负载均衡的QoS源路由协议,它将链路质量、跳数及中间节点的负载信息作为最优路径选择标准。详细阐述了该路由协议的工作机制,并给出了具体的代价函数计算公式。分析结果表明,该路由协议的确可以提高无线短波自组网的路由性能,能够满足短波自组网的特殊要求。
Considering the particularity of wireless transmission channels in HF Ad Hoe network, this paper presents a novel QoS-based source routing protocol by analyzing the effect of link quality and node load, which selects the best route based on the path quality and network load balance. The working mechanism of routing protocol and the cost function are described in detail. It can be concluded the protocol improves the muting performance and meets the needs of HF Ad Hoe networks.
