摘要
针对机会网络主流路由协议没有考虑到节点的社区特性,提出了一种基于社区的冗余效用混合转发机制。该算法从合理降低洪泛度和准确预测效用值方面出发,通过消息筛选、消息优先级和活跃节点机制对消息进行有效处理和转发。与经典的Epidemic和Prophet算法相比,该算法具有消息传达率较高、传输延时小和网络开销低的特点。
Since the mainstream routing algorithm of opportunistic network does not take into account the community characteristics, a hybrid routing algorithm based on community was proposed. In order to reasonably reduce the flooding and accurately predict the utility value, three mechanisms were introduced to effectively process and transfer the message including message filtering, message priority and active nodes. Compared with the classic Epidemic and Prophet algorithms, it shows that the algorithm can ensure a higher delivery ratio, less delivery delay and lower network cost.
