Abstract:
This paper demonstrates the usage of novel cognitive methods that improve the throughput of a WIMAX network by minimizing packet loss. The effects of the ant colony and fastest path routing algorithms on the throughput are investigated. A combination of Time Division Multiple Access (TDMA) and Orthogonal Frequency Division Multiple Access (OFDMA) spectrum sharing techniques is used. Data packet loss rate is minimized for real-time voice and video packet transmissions. A unicast mobile multimedia network with improved system throughput is provided with both routing methods, even for a small node count. © 2010 IEEE.
