Multiple-input-multiple-output (MIMO) technology, which is a recent breakthrough in wireless communications, has been shown to significantly improve channel capacity in single-user systems. However, obtaining a rigorous understanding of the possible MIMO gains in multihop networks is still an open topic. One grand challenge is that multihop wireless networks are interference limited and that the interference...
We study the throughput capacity of wireless networks which employ (asynchronous) random-access scheduling as opposed to deterministic scheduling. The central question we answer is: how should we set the channel-access probability for each link in the network so that the network operates close to its optimal throughput capacity? We design simple and distributed channel-access strategies for random-access...
In this paper, we analytically analyze the performance of a path selection diversity scheme for downlink packet delivery. In the scheme, the scheduled user, where scheduling is based on First In First Out (FIFO) queueing systems, tries to select the best end-to-end path quality among L possible relays including his downlink channel for packet delivery. In this system communication between users is...
