Gateway Placement under the Consideration of the Starvation of TCP Flows in Wireless Mesh Networks
Chuan Gang Liu, Chi Hui Chiang, Ya Wen Liao · Applied Mechanics and Materials · 2013
Wireless mesh networks are expected to provide wireless broadband access to Internet. In such networks, gateway placement is an important topic, which usually dominates the overall wireless performance, and hence there have been lots of the related works. However, recent paper even discovers that the starvation of TCP flows usually occurs near wireless gateways. Some TCP flows will starve just due to TCP flows of the node next to the gateway. Hence, possible ways to improve this critical issue should be developed urgently. However, until now, there have not been the feasible ways without modifying MAC and TCP mechanisms. Hence, in this paper, we plan the gateways placement under the consideration of this issue. To the best of our knowledge, this paper is the first work to plan gateway placement under considering the starvation of TCP flows. Our work also provides a new view in the field of planning wireless mesh networks.
