Dynamic Frame Control for TDD Based Wireless LAN

초록

In wireless LAN, radio frequency is an essential resource. But, because this radio frequency is a restricted resource that is shared worldwide, its efficient usage is required. In this paper, a frame and control structure is proposed to manage unbalanced traffic between uplink and downlink and fluctuations of stations traffic efficiently. And, the prototype for a wireless LAN with 1.5Mbits/sec is suggested. It allocates slots to stations dynamically depending on the traffics. And thus, the idle slots of the idle stations are shared with the heavy traffic stations, so the throughput is increased. As a result of analysis, dynamic transmission speed of 1Kbits/sec to 1.47Mbits/sec for each station, with the transmission delay of 0.5 seconds is possible.
