Abstract

Extensive work has been done in wireless multihop routing with several ideas based on shortest path or load balancing routing algorithms, that aim at minimizing end-to-end delay or maximizing throughput respectively. Backpressure is a throughput-optimal scheme for multihop routing and scheduling, while Enhanced-Backpressure is an incremental work that reduces end-to-end delay without sacrificing throughput optimality. However, the implementation of both theoretical schemes is not straightforward in the presence of 802.11 MAC, mainly because of their requirement for centralized scheduling decisions that is not aligned with the aspects of CSMA/CA.
