Design and Implementation of Bus Net Routing Algorithm

Bus Net is a kind of wireless network which is consist of buses and bus stations. It has the following features: 1) no end-to-end connection between source and destination, 2) intermittent connectivity, 3) high end-to-end delays. However, unlike the other DTNs, the node´s mobility in Bus Net is semi-deterministic, which means the node´s line is determined but the arriving time is undetermined. With these characteristics, some existing routing protocols are no longer fit. In this paper, we proposed a new routing protocol--Bus Net Transmission Routing Protocol (BNTRP) to solve the routing problem. We validate the performance of BNTRP in ONE simulation software, and the result shows that our protocol has a higher performance than other typical DTN routing protocols.
