Abstract:

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.
