If the transmission rate of transmission control protocol (TCP) does not match that of the medium access control (MAC) protocol in wireless ad hoc networks, it causes network congestion and network performance degradation. This letter proposes a new mechanism to feed back the real channel efficiency of MAC protocol to TCP. Comparing the real channel efficiency in MAC protocol with the virtual channel...
TCP unfairness is a widely existent problem over wireless mesh networks. The characters of shared wireless medium and location dependency conduce to the phenomenon. A Markov-based analytical model is proposed to analyze the influence factors of this problem in this paper. The unfairness issue over typical IEEE 802.11 based wireless mesh network was analyzed. Markov technique is adopted in analyzing...
