Cross-Layer Optimization for Wireless Sensor Network With Multi-Packet Reception

Free registration required

Executive Summary

In this paper, the authors consider how to exploit Multi-Packet Reception (MPR) to increase the capacity for a wireless sensor network. Since MPR behavior at the physical layer affects link layer scheduling, it is necessary to follow a cross-layer approach to obtain an optimal solution. Due to the complexity of crosslayer optimization, although MPR has great potential to increase capacity, optimal solutions are yet to be developed. The authors build constraints for the signal-to-noise-ratio requirement under MPR at the physical layer such that they can check the feasibility for a set of concurrent transmissions.
