Achieving Congestion Diversity in Multi-Hop Wireless Mesh Networks
This paper reports on the first systematic study of congestion-aware routing algorithms for wireless mesh networks to achieve an improved end-end delay performance. In particular, the authors compare 802.11 compatible implementations of a set of congestion-aware routing protocols against their implementation of state of the art shortest path routing protocol (SRCR). They implement congestion-aware routing algorithms BackPressure (BP), Enhanced-BackPressure (E-BP) adapted from, suitably adjusted for 802.11 implementation. They, then propose and implement Congestion Diversity Protocol (CDP) adapted from recognizing the limitations of BP and E-BP for 802.11-based wireless networks.
