In this paper, we describe FairMesh, which is the first attempt at mitigating the unfairness arising from physical layer capture (PLC) in 802.11 mesh networks. In the presence of PLC, which is surprisingly common in practical mesh networks, existing state-of-art solutions either fail to correctly identify the sender that needs to be throttled or are too aggressive in reducing the sending rate. FairMesh...
The network resource competition of today' data enters is extremely intense between long-lived elephant flows and latency-sensitive mice flows. Achieving both goals of high throughput and low latency respectively for the two types of flows requires compromise, which recent research has not successfully solved mainly due to the transfer of elephant and mice flows on shared links without any differentiation...
It is well known that the pervasive IEEE 802.11 MAC is intrinsically unfair [1, 3]. In particular, in the topology shown in Fig. 1(a), when links AB and CD both carry backlogged transmissions, the packets from sender A experience persistent collisions at node B while sender C enjoys collision-free transmission to D. Node A can transmit successfully only if it is able to “insert” its packets into the...
