In this paper we study the interactions of TCP and IEEE 802.11 MAC in Wireless Mesh Networks (WMNs). We use a Markov chain to capture the behavior of TCP sessions, particularly the impact on network throughput performance due to the effect of queue utilization and packet relaying. A closed form solution is derived to numerically determine the throughput. Based on the developed model, we propose a...
In mobile cognitive radio networks, the expected delay for a packet to be delivered to its destination via a singlehop communication (without relaying) is a fundamental metric that can provide a guidance to multi-hop routing protocol design and route planning. In this paper, we characterize the impact of PU activities, spectrum availabilities, channel bandwidth, MAC access, SU mobilities, and interference,...
Recently the Effective Capacity of multi-user wireless scheduling has been analyzed based on large deviation principle. The users' queue length distribution bound of wireless scheduling algorithm such as round robin and rate maximum was discussed based on Effective Capacity analysis. But for Queue Length Based (QLB) Rate Maximum scheduling algorithm, the analysis result is only limited to system bound...
Three-Network Convergence” refers to the way the telecommunications network, the TV broadcasting network, and the Internet converge and develop together, connecting the three networks and sharing their resources in the provisioning of Internet access, TV, and telephone services. A related term “triple play service” refers to the provisioning of the three services over a single broadband connection...
