Thanks to their flexibility and their simplicity of installation, Wireless Mesh Networks (WMNs) allow a low cost deployment of network infrastructure. They can be used to extend wired networks coverage allowing connectivity anytime and anywhere. However, WMNs may suffer from drastic performance degradation (e.g., increased packet loss ratio and delay) because of interferences and congestion. Generally,...
In this correspondence, we consider the problem of delay optimal rate allocation in a (potentially asymmetric) multiaccess channel. The rate feasibility region of such a network is well studied and is shown to be of a polymatroid structure. We consider this problem with unsaturated sources, i.e., jobs arrive at sources at random times and the source has the possibility of being empty. In such a setting,...
Internet Relay Chat (IRC) is a critical application in military networks for maintaining situational awareness and conducting battle management at all echelons. But these networks are often subject to frequent disconnections, limited bandwidth, and long delays, especially when using satellite services and field radios. Such conditions are inhospitable to TCP, and thus the standard IRC protocol, which...
