Abstract: Aiming at the difference of contact frequency and buffer resources between fixed relay nodes and mobile nodes in the sparse opportunistic networks, a buffer management strategy combining the importance of fixed relay nodes with message correlation was proposed in the multiple copy routing protocols.The proposed strategy can reduce the number of redundant messages in the buffer of fixed relay nodes by interacting the contact information and the message queue information of fixed relay nodes and mobile nodes so that using the buffer space of fixed relay nodes reasonably.Experiments show that the proposed buffer management strategy can improve the cache space utilization of fixed relay nodes on the basis of guaranteeing the successful rate of message transmission.
