System for spatial backoff contention resolution for wireless networks

摘要

Spatial backoff methods allow source stations to search for appropriate carrier sense threshold and transmission rate operating points to improve network aggregate throughput. In one method, each source station performs a search process to find the best carrier sense threshold and transmission rate, based on a defined utility function. In a second method, each source station dynamically adjusts its carrier sense threshold and transmission rate upon successful transmissions or failures, based on some heuristic measures. Spatial backoff methods may lead to gains in performance.
