We consider the problem of joint routing, scheduling and power control in a multihop wireless network ensuring Quality of Service (QoS) to different users. The QoS to a user may be the stability of its queues in the network or a minimum rate guarantee. Transmission channels may experience fading. Power is consumed only for transmission of data. We consider the case when the power required is a linear...
We propose and evaluate the performance of communication algorithms for the transmission time minimization problem on multihop wireless networks modelled by directed graphs with multiple channels. We derive a lower bound for the minimum transmission time so that our heuristic solutions can be compared with optimal schedules. We present one randomized routing algorithm and nine heuristic transmission...
There is growing interest in employing ultra-wideband (UWB) communication systems at the physical layer for multihop wireless networks. Recent efforts show that networking problems involving UWB systems should follow a cross-layer approach with consideration at multiple layers. Due to the nonlinear nature of the optimization problem, there are very limited theoretical results for this important problem...
