Non-uniform node densities occur and intermittent links exist in highly dynamic ad hoc networks. To fit these networks, researchers usually combine delay tolerant network (DTN) routing protocols and mobile ad hoc network (MANET) routing protocols. The DTN protocol separates end-to-end links into multiple DTN links, which consist of multi-hop MANET links. Determining how to arrange DTN links and MANET...
Performance of safety applications of vehicular networks largely depends on the reliability of the communication channel. However the IEEE 802.11p channel is unreliable according to the previous measurement-based work, which reported that the whole communication range is a “gray-zone” and the packet inter-reception time suffered from blackouts with a relatively high probability. Besides the 5.9 GHz...
Most of the existing DTN routing algorithms have been studied in the simulation environment. They are not sufficiently used to the historical location and historical neighbor's information. So AAaS(Area Approaching and Spray-and-Wait) routing algorithm is proposed, which considers the practicability of the algorithm and the rules of the node's movement and the law of the meeting. AAaS divides the...
The popular method for MANET to access the Internet is choosing some gateways through which MANET can act as a subnet of the Internet. In these solutions, gateways will be the bottleneck of the whole network. Meanwhile, gateway selection and handoff are also the problems. Since aforesaid problems, a new protocol was implemented on embedded devices based on iAODV, and route optimization and link failure...
