基于动态社会关系的机会路由研究
RESEARCH ON OPPORTUNISTIC ROUTING BASED ON DYNAMIC SOCIAL RELATION
摘要
Abstract
In opportunistic networks , the nodes are rational and strongly dynamic , there are selfish nodes that are not willing to share the bandwidth or other resources with others .Aiming at this problem , we propose a routing method which is based on dynamic social relations , namely, SRR.SRR evaluates the social relationship between the nodes in opportunistic networks through physical social relation of nodes and their encountering probability , dynamically updates and calculates the social relationship matrix between the nodes .According to the social relationship matrix , the message source node chooses suitable member node as the relay to deliver messages to the destination node , and avoids in utmost extent the possibility of discarding the massage being passed by the selfish nodes in network .Simulation results show that in opportunistic networks with more selfish nodes , SRR effectively improves the successful message delivery probability than other methods .关键词
