Two-Dimensional Downlink Burst Construction in IEEE 802.16 Networks
The characteristics of the IEEE 802.16 wireless communication cause considerable difficulty in burst construction. The proposed BCO algorithm maximizes the throughput during downlink burst construction for each connection. BCO not only complies with the downlink burst structure specified in IEEE 802.16 standards, but also considers the issues of external fragmentation, internal fragmentation, and optimal block exploration. Compared to the authors' previous study, which focused on constructing the uplink burst with a multi-rectangular shape, this paper designs BCO for constructing the rectangular downlink burst, provides verification that BCO maintains united available bandwidth during burst construction, and compares it with other downlink burst construction algorithms in terms of total throughput, IUSR, and EUSR.
