Proportionally fair allocation of end-to-end bandwidth in STDMA wireless networks
We consider the problem of designing distributed mechanisms for joint congestion control and resource allocation in spatial-reuse TDMA wireless networks. The design problem is pos...

Bandwidth Balancing in Multi-Channel IEEE 802.16 Wireless Mesh Networks
Abstract— In wireless mesh networks, the end-to-end throughput of traffic flows depends on the path length, i.e. the higher the number of hops, the lower becomes the throughput...

Self-Organizing Dynamic Fractional Frequency Reuse in OFDMA Systems
—We describe an algorithm for sub-carrier and power allocation that achieves out-of-cell interference avoidance through dynamic fractional frequency reuse (FFR) in downlink of ce...
