In this paper, we present a new look at the sensing-throughput tradeoff problem. Distinguishing with the previous work, the throughput in our paper is defined as the number of data bits per second received correctly rather than the achievable rate. This choice facilitates the investigation on optimizing throughput for a frame based wireless data transmission scheme from a general point of view. Our...
Based on the analysis of TCP performance of over the two ways of IEEE 802.11 DCF (RTS/CTS and CSMA/CA), TCP flows becomes unstable when WLAN is in high load. In this paper, we propose a novel backoff algorithm for IEEE 802.11 DCF named as ACWB (adaptive contention window backoff) with cross-layer optimization. Its basic idea is to dynamically adjust the size of the contention window by the estimation...
