为了改善GPCR协议中的局部最优、路由环路及在稀疏网络中性能不佳等问题,提出了一种基于权重选择的 GPCR(W-GPCR)协议。深入分析节点间距离、运动方向及密度等参数对车辆节点路由的影响,针对现有路由问题,建立复合参数权重模型并设计计算方法,在不同的场景下自适应选择权重参数比,从而得到最优下一跳中继节点。为了验证W-GPCR方法的性能,将其与传统的GPCR和GPSR等现有方法进行对比。结果表明, W-GPCR方法在分组投递率、端到端时延和平均跳数方面均更优。
To improve the performance in sparse networks
local optimum
and routing loop in the greedy perimeter coordinator routing (GPCR) protocol
the weighted-GPCR (W-GPCR) protocol was proposed.The relationship between vehicle node routing and other parameters such as the Euclidean distance between node pairs
moving direction and density was profoundly analyzed
the composite parameter weighted model was established and the calculation method was designed for the existing routing problems
the weighted parameter ratio was selected adaptively in different scenarios
so as to obtain the optimal next-hop relay node.In order to verify the performance of the W-GPCR method
the proposed method was compared with the existing methods such as the traditional geographic perimeter stateless routing (GPSR) protocol
GPCR and so on
and the results show that the proposed method is superior to the package delivery ratio
end-to-end delay
and average hop count.
