Modern battlefield communications environment is very complex, the sensor network is extremely prone to splitting, in this situation the traditional routing protocols will fail, and opportunistic routing is regarded as the most promising techniques.While people have proposed three kinds of routing mechanism to handle the routing problem what the splitting network brings.They are: "Receive-Carry-Transmit" mechanism;"Multiple Forwarding" mechanism;"Nodes Exchanging Information in Pairs" mechanism, and there have been some routing protocols such as Epidemic, Prophet Router, First Contact Router to use, there is also insufficient.For example, the existing routing algorithm only allows a node to set up one single sending connection at a time,which greatly limits the diffusion rate of data in opportunistic networks.In this paper, we study the potential benefits of the multiple sending connections between any two nodes which move into each others communication range.We develop a new protocol named MSC which is based on Epidemic routing.By using "one", which is a dedicated simulation software for opportunistic, the results show that MSC may improve packets diffusion rate in the network and has benefits in terms of the transmission delay and the delivery success rate compared to Epidemic, Prophet Router, and First Contact Router.
