摘要：

针对延迟容忍网络(DTN)中喷雾等待(SaW)路由协议在转发消息时选择中继节点的盲目性,提出一种基于节点效用的路由协议SaW-Utility.此路由协议在转发消息时,将根据节点剩余缓存和节点交付概率等因素选择中继节点,从而减少中继节点选择的盲目性.仿真结果表明,相比于SaW路由协议,SaW-Utility路由协议明显提高了消息转发成功率,降低了网络开销.

Abstract:

Spray and wait (SaW) routing protocols select relay node arbitrarily in message forwarding process. Aiming at the arbitrariness, a new routing protocol, SaW-Utility, is proposed based on the utility of nodes. When messages are forwarded, SaW-Utility selects relay nodes according to the utility of nodes, such as the sizes of remaining buffer, success rate of message delivery, and etc., so that the arbitrariness can be overcome. The simulation results show that the proposed routing protocol significantly improves the success rate of message forwarding and reduces network overhead compared with SaW routing protocols.

Key words: delay tolerant network, spray and wait routing protocol, utility of node
