Utility forwarding protocol based on mobile characteristic for opportunistic networks
机会网络中基于移动特征的效用转发协议*

For forwarding protocol in no-community networks does not consider the non-totally random node mobility, this paper presented an utility forwarding protocol based on mobile characteristic (BMCU).It described the node characteristic during moving by similarity and activity. In order to complete appropriate divergence and submission of message, it used the more active nodes to get copy of message from the sender. It suppressed divergence of the copies by similarity and utility comparison. Simulation results show that BMCU can get higher delivery ratio, also improve the routing efficiency with relatively stable delay and lower energy consumption.
