Maximizing Throughput in Wireless Multi-Access Channel Networks

Free registration required

Executive Summary

Recent advances in the physical layer have enabled the simultaneous reception of multiple packets by a node in wireless networks. In this paper, the authors present a generalized model for the throughput optimization problem in multi-hop wireless networks that support Multi-Packet Reception (MPR) capability. The model incorporates the multi-access channel, which accurately accounts for the achievable capacity of links used by simultaneous packet transmissions. The problem is modeled as a joint routing and scheduling problem. The scheduling subproblem deals with finding the optimal schedulable sets, which are defined as subsets of links that can be scheduled or activated simultaneously.
