Keyword容延迟网络 行星际网络 保管传输 路由协议
Abstract为解决星际网络场景下的数据传输问题,提出了一种星际容延迟网络路由协议:利用节点的历史连接信息来预测该节点与其各个邻居节点的连接恢复时间;当两个位于同一个域的节点互相连接时,交换彼此的连接时间预测表,并据此决定是否需要使用对方作为中继节点;深空节点的存储资源常常受限,在进行路由选择时将节点的存储区消耗情况也纳入决策。使用NS2进行地-火通信场景仿真,使用一种改进的泛洪路由和一种仅选择网关节点作为下一跳选择的路由策略作对比。仿真结果表明相比其他两种协议,提高了14%的投递成功率并减少了50%的平均传输延迟,并更有效的利用了节点存储资源。
Other AbstractA novel interplanetary DTN routing protocol (IDRP) is designed to provide a general networking solution over interplanetary network scenarios. IDRP enables DTN nodes to estimate the recovery time to its neighbor nodes using the historical connection information. When two DTN nodes in the same region contact each other, they exchange their estimations to decide whether to use each other as a relay. For storage resource is constraint in deep space nodes, IDRP also takes storage consumption into consideration. Simulations based on NS2 were conducted in a Mars-to-Earth scenario. A modified epidemic routing strategy and an only-gateway-selected routing strategy are used as contrast. The simulation results show that IDRP achieves 14% higher delivery ratio and 50% less average transmission delay than the other two strategies, as well as better storage utilization.
