An Improved CP-BSW Routing Protocol Based on Delivery Possibility in Opportunisitic Network

There are a large number of nodes in the opportunistic network, and the data in the network is stored and carried by the mobility of the nodes. Different devices in different areas interact through the mode of storing-carrying-forwarding messages. According to the classic routing protocol, an improved algorithm (CP-BSW) is proposed which consider the delivery posibility of the classic routing protocol `Binary Spray and Wait' in this paper. The simulation results show that the proposed routing protocol can improve the message delivery rate and reduce the delivery delay.
