There is wide consensus that properly taking into account wireless interference is necessary to design high performance link scheduling algorithms for multi-hop networks. However, most approaches in the literature use simplified models, which significantly abstract from the physical behavior of wireless links. Indeed, the main problem in representing the wireless propagation conditions with a proper...
We consider the problem of exchanging packets from the individual queues at multiple wireless terminals with the assistance of a single relay node. In an earlier paper, we studied this for a backlogged traffic model, where each node always had packets to transmit. Here, we consider stochastically varying packet traffic and compare the stable operation under plain routing, and digital and analog network...
The Department of Electronic Engineering of Beijing Institute of Technology is integrating emerging interconnect technologies with other high-performance technologies to meet the demanding requirement of future, real-time signal processing applications. For next-generation, scalable, modular and adaptable signal-processing system, a universal, flexible and high-performance signal processing module...
Three applications in wireless networks where model-free stochastic learning is applicable, are discussed. The learning based optimization problems are formulated and simulation results are presented. Some open issues are also discussed.
In this paper, we propose an adaptive pacing scheme at the link layer for IEEE 802.11 based multihop wireless networks. Our objective is to improve the performance of higher layer protocols without any modifications to them. Our adaptive pacing scheme estimates the four-hop transmission delay in the network path without incurring any additional overheads, and accordingly paces the packets to reduce...
