移动社会网络是一种具有间歇连通特性的延迟容忍网络,因此路由具有挑战性.同时移动社会网络具有一定的社会结构特征,节点的社会行为具有一定规律性.利用网络节点的访问地点偏好性而形成的城市热点区域以及节点移动的规律性,提出了一种基于热区的网络路由协议 HRP.HRP 协议在进行数据路由时依据节点对区域访问的频度,区域访问频度越高的节点活跃度越强,因此有更高的概率遇到目标节点.实验结果表明,HRP协议的平均数据传输成功率比 BUBBLE 协议的约高10%,而平均数据传输次数则比其约少30%,获得了较好的网络性能.

Routing is a challenged task for mobile social networks which are typical delay tolerant networks with intermittent connectivity.However,mobile social networks have inherent properties of social structure and the nodes often behave regularly,which could be used to assist in making routing decision.In this paper,a Hot-zone based Routing protocol is presented based on the hot-zones due to preference location the nodes visit and the regular mobility of the nodes.HRP forwards data based on the frequency of the visiting zone of the nodes.The higher the visiting frequency of the nodes is,the higher the probability of meeting the destination node is.Simulation results show that the average data delivery ration of HRP is 10% higher than that of BUBBLE with 30% less data transmission.
