摘要 考虑到容迟移动传感器网络(DTMSN)的资源受限性,提出了一种基于综合效用的多副本喷射转发路由算法,通过计算综合效用值来指导消息副本在网络中的复制与转发.同时,为了减少冗余副本所带来的影响,还提出了一种与之相匹配的缓存管理机制.仿真结果表明,算法在有效性、可靠性和资源的使用等方面相比SWR算法均有不同程度的改善. Considering the limited network resources, we propose an integrated utility based spray and forward routing algorithm for delay tolerant mobile sensor networks （DTMSN）. To deal with the message redundancy, a buffer management scheme is also proposed for this algorithm. Simulation results show that, compared with spray and wait routing （SWR） algorithm, this proposal could achieve better network performances in efficiency, reliability and resource utilization.
