Desynchronization-based weighted scheduling adaptive to traffic load for wireless networks

Abstract

Under regular or heavy traffic conditions, contention-free mechanisms such as time division multiple access (TDMA) are considered as under layer mechanisms in wireless networks. In TDMA mechanisms, links are scheduled by assigning different time slots for links that interfere each other. In this paper, we propose a self-organizing link scheduling mechanism for single-hop wireless networks considering traffic load of each wireless link. The proposed mechanism is based on a conventional desynchronization-based TDMA mechanism. Through simulation evaluations, it is shown that our proposed mechanism can schedule links in a self-organizing manner in accordance with traffic load of each link.
