We analyze the problem of buffer sizing for TCP flows in 802.11-based Wireless Mesh Networks. Our objective is to maintain high network utilization while providing low queueing delays. The problem is complicated by the time-varying capacity of the wireless channel as well as the random access mechanism of 802.11 MAC protocol. While arbitrarily large buffers can maintain high network utilization, this...
Future wireless networks are expected to provide quality of service (QoS) guarantees. QoS requirements at the networking layers include data rate, delay bound, and packet error probability. However, these QoS requirements pose significant challenges since wireless fading channels may cause severe QoS violations. To mitigate fading effects, adaptive schemes such as transmission rate control and power...
