Abstract

Abstract: An improved opportunistic routing algorithm which is called RSSI-PROPHET，is proposed for opportunistic networks.The algorithm combines the node access frequency and the received signal strength indication in the design.In order to suppress the proliferation of reached message copies，a message arrival notification mechanism is added in the algorithm.The algorithm needs no additional device support and does not depend on pre-existing network topology.Simulation results show that the algorithm significantly reduces the consumption of the buffer space and improves the efficiency of the system.

Key words: opportunistic networks, opportunistic routing, RSSI-PROPHET routing algorithm

摘要： 针对机会型网络提出一种改进的机会网络路由算法RSSI-PROPHET。该算法结合节点接触频率和接收信号强度指示值RSSI（Received Signal Strength Indication）信息进行设计，并加入一种消息到达通告机制来抑制已达消息副本的扩散。算法不需额外设备支持，不依赖于既存的网络拓扑。仿真结果表明，该算法明显减小了设备缓存空间的消耗，提高了系统效率。
