Abstract

Routing is a very challenging task in opportunistic networks due to the lack of continuous end-to-end path between nodes. To improve the routing performance, a type of community-based routing protocol is presented. This routing generally turns to the social attributes of nodes to construct the community, and utilizes community characteristics (nodes within the same community come in contact with each other more frequently) to select the relay nodes and make the forwarding decisions. Unfortunately, this routing has a problem of transmission bottleneck between communities. To address this issue, we propose an enhanced community-based routing assisted by ferry in opportunistic networks. This routing resorts to some super-nodes as ferry nodes to ferry messages between communities in order to overcome the network division. The simulation results demonstrate the efficiency and effectiveness of the proposed scheme by comparing it with existing routing schemes.
机会网络中基于社区的轮渡改进路由
在机会网络中,由于节点之间缺乏连续的端到端路径,路由是一项非常具有挑战性的任务。为了提高路由性能,提出了一种基于社区的路由协议。这种路由一般利用节点的社会属性来构建社区,并利用社区特征(同一社区内的节点相互接触更频繁)来选择中继节点并做出转发决策。不幸的是,这种路由存在社团间传输瓶颈的问题。为了解决这一问题,我们建议在机会主义网络中增加渡轮辅助的社区路线。这种路由利用一些超级节点作为传递节点在社区之间传递消息,以克服网络划分。仿真结果与现有的路由算法进行了比较,验证了该算法的有效性和有效性。
