A better solution to the problem seems to utilize the data forwarding functionality of mobile stations under the multihop cellular network architecture. In this paper, we propose a base-driven bridging protocol for the wirless multihop cellular network. Comparing to the traditional cellular netowrk, mobile stations in the multihop cellular environment can forward data for other stations, and less transmission range of both mobile stations and base stations reduces battery consumption. As long as there is no interference or over- lapping, there can be several data connections in one cell at the same time. Therefore, we will have a higher throughput and solve the bandwidth problem. In our proposed bridging protocol, the mobile station must broadcast Hello message which contains its IP address, Mac address and other information periodically. Base stations calculate the shortest paths among mobile staitons and transmits the results to mobile stations. Data frames will then be transmitted following these paths.
