在感知无线电自私ad hoc网络环境下提出一种低代销的诚实能效路由（Lowest Cost Path,LCP）,将路由的开销结合对主用户的干扰和节点剩余能量,利用格罗夫斯-克拉克-威科瑞（Vickrey-Clark-Groves,VCG）定价机制给LCP上每个中继节点以一定报酬促使节点之间的合作,并证明VCG机制下节点真实的反映自身的类型是一个占优策略。仿真结果表明,该路由算法有效实现了感知无线电自私ad hoc网络的诚实能效路由,与现有最短路径路由协议比较,该协议具有更好的性能。

A low-cost truthful energy-efficient routing protocol is proposed in cognitive selfish ad hoc networks.Combining the routing cost with the interferences to primary user and their remaining energy,some payment is given to each relay node in lowest-cost path by using VCG mechanism to promote the cooperation between nodes and prove it is a dominant strategy that a node reflects its type truthfully in VCG mechanism.The simulations results show that this routing protocol can implement effectively low-cost truthful energy-efficient in cognitive selfish ad hoc networks and have better performance compared with existing routing protocols.
