A Routing Algorithm Based on Small World and Energy Efficiency in Delay Tolerant Network
-
摘要: 容迟网络(DTN)具有小世界特性,一条消息至多需要五至六跳中间节点就可从源节点到达目的节点。为此,算法(TBSF)结合小世界特性通过限制中间节点数目来提高消息的交付率,但该方法没有考虑节点的能耗以及社会权威的问题。该文从节点能效与社会权威出发提出一种改进的算法。该算法设计了能量控制机制,并在扩展度中心性的基础上讨论节点的社会权威,在消息的转发过程中突出权威节点的作用。仿真结果表明,该算法在保持较高消息交付率的同时能够降低网络的能耗。
