Community-Based Energy-aware routing protocol in mobile social networks

Abstract

Mobile social network (MSN) with delay tolerant nature of intermittent network connectivity and the node behavior of the network has certain social characteristics, which is helpful to the data sharing and transmission between the nodes. At present, most social routing algorithms do not take into account the energy consumption of the nodes, and the energy consumption of the mobile nodes is not balanced, so the performance optimization can not be achieved. In this paper, we proposes the community-based energy-aware routing protocol——CBEAR, an MSN network dynamic partition into several different community, transferring and sharing news in the intra-community and inter-community, considering node energy consumption rate and the encounter probability between node and each community to make routing decisions, avoid some nodes’ energy consumption is too fast problem, to realize load balance between nodes. By comparison with existing routing protocols through extensive simulations, the simulation study show that although the CBEAR protocol has some delay performance, it has achieved better performance in terms of data transmission success rate, protocol overhead ratio and energy balance.
