移动社交网络中基于朋友圈的路由机制
Routing mechanism based on friend groups in mobile social network
摘要
Abstract
Aiming at the discontinuity connection among nodes and the limitation of resources in mo-bile social network(MSN), a routing mechanism based on friend group is proposed to implement data routing quickly and efficiently.First,under the application scenario of a campus MSN,a friend group construction algorithm based on core edge and threshold is proposed,and the network is divid-ed into some overlapping friend groups that are closely linked.The single copy model is adopted, and firefly intelligent optimization algorithm is introduced in the proposed mechanism,which utilizes the phototropic behavior and stochastic disturbance behavior to intelligently select relay nodes, thus conducting efficient message routing within and among the friend groups.Simulation results show that,compared with the mechanisms of direct delivery routing,prophet routing,and community-aware opportunity routing,the proposed mechanism can improve the message delivery probability with less average hops,and reduce network overhead and average delay,providing a better performance.关键词
