An Adaptive Routing Protocol for Bus Networks

Providing Internet access on buses allow people to read news, check emails, watch sport games, and hence can greatly improve the quality of people´s life. This paper proposes an adaptive routing protocol, called R-BUS for a bus network. R-BUS selects a route based on the link´s lifetime and its communication signal quality. The protocol takes the bus mobility and the radio propagation model into account. A real map scenario is employed to evaluate the performance through simulation. The simulations show that R-BUS can guarantee the communication quality and also increase the route reliability. Compared to the existing routing protocols, R-BUS can achieve higher packet delivery ratio, lower average packet delay and lower control overhead.
