【摘要】：针对容迟网络高延迟、间歇性连接、节点频繁移动、能量和缓存资源受限等本质特点,提出一种基于节点能力模型的容迟网络路由算法CM-RSD。该算法将基于节点活跃度和可用能量比的能力模型和多副本限额转发策略相结合,使消息副本向递交能力更强的节点扩散,从而提高消息递交的成功率,同时实现对资源开销的控制。此外,CM-RSD在选择中继节点时,还充分考虑了节点的能量状态,以避免消息副本向能量不足的节点扩散,从而有效保障网络节点的存活率。仿真实验表明,无论是节点密度、副本配额,还是节点移动模型的影响,CM-RSD算法在消息递交成功率、资源消耗、递交延时、能量消耗、扩展性等方面都表现出了良好的性能。
[Abstract]:Aiming at the characteristics of high delay, intermittent connection, frequent movement of nodes, limited energy and buffer resources, a routing algorithm CM-RSD-based on node capability model is proposed. The algorithm combines the capability model based on node activity and the ratio of available energy with the multi-replica quota forwarding strategy to spread message replicas to nodes with stronger delivery ability, thus improving the success rate of message delivery. At the same time, the control of resource overhead is realized. In addition, CM-RSD also considers the energy state of the node when selecting the relay node, so as to avoid the spreading of message copy to the node with insufficient energy, so as to ensure the survival rate of the network node effectively. Simulation results show that the CM-RSD algorithm has good performance in message delivery success rate, resource consumption, delivery delay, energy consumption, scalability and so on, both in terms of node density, replica quota and node mobility model.
