【摘要】：針對容遲網(wǎng)絡高延遲、間歇性連接、節(jié)點頻繁移動、能量和緩存資源受限等本質(zhì)特點,提出一種基于節(jié)點能力模型的容遲網(wǎng)絡路由算法CM-RSD。該算法將基于節(jié)點活躍度和可用能量比的能力模型和多副本限額轉(zhuǎn)發(fā)策略相結(jié)合,使消息副本向遞交能力更強的節(jié)點擴散,從而提高消息遞交的成功率,同時實現(xiàn)對資源開銷的控制。此外,CM-RSD在選擇中繼節(jié)點時,還充分考慮了節(jié)點的能量狀態(tài),以避免消息副本向能量不足的節(jié)點擴散,從而有效保障網(wǎng)絡節(jié)點的存活率。仿真實驗表明,無論是節(jié)點密度、副本配額,還是節(jié)點移動模型的影響,CM-RSD算法在消息遞交成功率、資源消耗、遞交延時、能量消耗、擴展性等方面都表現(xiàn)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.
