A routing protocol based on DoC-ACK mechanism in opportunisitic network

Opportunistic network is a kind of network which does not have a definite path from the source node to the destination node. It can only communicate when nodes meet each other. According to the classic routing protocol in opportunistic network, a routing protocol is proposed which consider the duration of historical connections with acknowledgement mechanism (DoC-ACK) in this paper. The simulation results show that the proposed routing protocol can substantially improve the message delivery rate and significantly reduce the overhead rate without changing the transmission delay basically.
