【摘要】：根据延迟容忍网络中人类运动体现出的地点偏好特征,提出了一个社会感知路由协议,并采用了点到社区的多播方式。相应地设计了节点分布式地获取社区及其地理位置的方法,其中的分布式社区检测算法独立于路由协议,并具有灵活、准确的特征。协议以文中发掘出的新的社会感知量——地点偏好为中心,将消息不断地向目的社区所在的地理位置推进,在消息抵达社区成员节点之后利用社区结构所蕴含的强社会关系在社区内部继续传送消息,并激活消息复制机制。本协议基于社会网络分析,从地理位置的角度准确预测节点运动从而进行路由。实验结果表明:本协议与两个未采用地点偏好的社会感知路由协议相比,在不增加协议开销的情况下提升了至少10%的发包成功率;在社区及其地理位置已知的场景下具有更好的性能,在保持最高的发包成功率的同时缩减了50%以上的开销。
[Abstract]:According to the location preference characteristics of human movement in delay tolerance networks, a social-aware routing protocol is proposed, and a point-to-community multicast scheme is adopted. The distributed community detection algorithm is independent of routing protocol and has the characteristics of flexibility and accuracy. The protocol centers on the new social perception-location preference found in the text, and pushes the message to the geographic location of the target community. After the message arrives at the community member node, the strong social relations contained in the community structure are used to continue to transmit the message within the community and activate the message replication mechanism. Based on the analysis of social network, this protocol can accurately predict the movement of nodes from the point of view of geographical location. The experimental results show that compared with the two social-aware routing protocols without site preference, the proposed protocol increases the success rate of outputting by at least 10% without increasing the overhead of the protocol. Better performance is achieved in the community and in scenarios where the geographical location is known, reducing the overhead by more than 50% while maintaining the highest success rate of contracting out.
