以前的延迟/中断容忍网络(DTN)中的地理路由方案只考虑节点移动性相同的同构场景。受这一差距的启发,我们转向设计一种基于DTN的异构场景下的地理路由方案。系统地,我们的目标是通过两个步骤来实现的:1)我们首先提出了在同构场景下,通过有限数量的副本来传递消息的“最佳地理中继(TBGR)”路由方案。在网络密度稀疏的情况下,我们进一步克服了TBGR的局部极大值问题,这与分簇无线传感器网络等密集网络中的努力不同。2)在此基础上,对TBGR进行了扩展,提出了考虑个体节点访问偏好(称为非相同节点移动性)的“最佳异质地理中继(TBHGR)”路由方案。在一个真实的异质场景下的大量实验结果表明,在可靠的消息传递和较低的路由开销方面,TBHGR比文献工作更具优势。
Previous geographic routing schemes in delay/disruption tolerant networks (DTNs) only consider the homogeneous scenario where nodal mobility is identical. Motivated by this gap, we turn to design a DTN based geographic routing scheme in heterogeneous scenario. Systematically, our target is achieved via two steps: 1) We first propose, “The-best-geographic-relay (TBGR)” routing scheme to relay messages via a limited number of copies, under the homogeneous scenario. We further overcome the local maximum problem of TBGR given a sparse network density, different from those efforts in dense networks like clustered wireless sensor networks. 2) We next extend TBGR for heterogeneous scenario, and propose “the-best-heterogeneity-geographic-relay (TBHGR)” routing scheme considering individual nodal visiting preference (referred to nonidentical nodal mobility). Extensive results under a realistic heterogeneous scenario show the advantage of TBHGR over literature works in terms of reliable message delivery, while with low routing overhead.
