Summary: | 碩士 === 國立交通大學 === 資訊科學學系 === 86 === As we require more bandwidth for wireless communication, the
transmission range will decrease in order not to violate the
safety limit of radio power. 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.
