Reconsidering wireless systems with multiple radios
The tremendous popularity of wireless systems in recent years has led to the commoditization of RF transceivers (radios) whose prices have fallen dramatically. The lower cost allo...

Per User Throughput in Large Wireless Networks
— Previous results show that a node’s throughput scales poorly as the network size increases when every node has traffic. However, in many cases, only a fraction of nodes in l...

A Polynomial-Time Approximation Algorithm for Weighted Sum-Rate Maximization in UWB Networks
— Scheduling in an ad hoc wireless network suffers from the non-convexity of the cost function, caused by the interference between communication links. In previous optimization t...
