Coordinated scheduling/beamforming (CS/CB) is regarded as a promising technique with non-ideal backhaul (NIB). However, due to the high latency of the NIB, the channel state information (CSI) and coordinated scheduling decisions will be severely delayed or even lost, resulting in serious system performance deterioration. To address this issue, an adaptive CS/CB scheme consisting of a semi-static coordinated...
We formulate the problem of robots ferrying messages between statically-placed source and sink pairs that they can communicate with wirelessly. We first analyze the capacity region for this problem under both ideal (arbitrarily high velocity, long scheduling periods) and realistic conditions. We indicate how robots could be scheduled optimally to satisfy any arrival rate in the capacity region given...
With K-hop interference model, especially when K ≥ 2, the throughput-optimal centralized scheduler needs to solve a NP-Hard problem. It leads to the desire of a distributed, low-complexity but throughput-optimal scheduling algorithm. We generalize a randomized scheduling framework for a K-hop interference model and develop two randomized distributed scheduling algorithms which can be integrated into...
