基于节点能力模型的容迟网络路由算法
Capability Model Based Routing Strategy in DTN
摘要
Abstract
Delay-tolerant networks (DTNs) are a type of emerging networks characterized by extraordinarily long delay paths and frequent network partitions. For the distinct characteristics of DTNs, routing becomes one of the most challenging open problems. This paper presents a routing strategy based on capability model in DTN, called CM-RSD. The CM-RSD combines capability model with quota-based routing strategy, and sprays more message copies to stronger nodes. Furthermore, this strategy can select relay nodes based on the energy states of nodes, thus protecting the survival of network nodes effectively. Our simulation results show that the CM-RSD can improve the message delivery ratio significantly while keeping the overhead ratio low in distinct scenarios with different node densities, quota of copies, and mobility models.关键词
