A Channel Allocation Based WiMax Topology

Free registration required

Executive Summary

Along with information technology of flourishing, the popularization rate of the wireless communication equipment is higher and higher. However, WiMax is the one of new broadband wireless technologies. It can provide high data rate, large network coverage, and different application services. When large amount of users use these applications, the network may occur transmission collision and broadcast storm. The most important factor to cause this problem is the competition of communication bandwidth by different service requests. However, due to the limitation of communication channel, the OFDMA is used in this research to divide the channel into several sub-channels and those sub-channels can be provided for different users.
