摘要
提出一种基于合作性的机会网络高效路由算法(CEER算法)。首先,通过将待发送的Request控制分组中这些节点所产生的数据分组对应的各比特位置零,从而避免对这类冗余数据分组的发送。此外,优先发送目的地址为对方节点的数据分组,提高投递效率。理论分析和仿真结果表明,所提算法可以有效提高投递率,缩短投递时延,减少资源消耗等。
To address the problem, an efficient routing algorithm based on cooperation （Cooperation based Efficient Epi- demic Routing, CEER） is proposed. Firstly, through setting the bits in the Request control packet to be sent, which are corresponding to these data packets mentioned above to zeros, avoiding the send of redundant data packets. Moreover, the data packets destined to the opposite nodes obtain the priority to be transmitted, so as to improve the delivery efficiency. Theoretical analysis and extensive simulation results showed that the proposed algorithm can effectively increase the de- livery rate, shorten delivery delay and cut down the resource overhead and so on.
