A position-based routing protocol for metropolitan bus networks

A network connecting all the public service buses as nodes in an ad hoc network can provide a wide range of services for operators and commuters. This paper proposes a new position-based routing protocol for such metropolitan bus networks, which makes use of street information like street map and bus route information to identify a stable geographic route with high connectivity for data delivery. Furthermore, the proposed protocol can cope with partitioned networks and route messages across partition boundaries. Preliminary simulation result shows that it achieves significant performance improvement compared to other similar routing approaches.
