COCKTAIL PARTY: SIDE CONVERSATIONS AND TALKING OVER IN WIRELESS MESH NETWORKS

摘要

The present disclosure proposes a method for minor modifications to the Distributed Coordination Function (DCF) channel access mechanism in order to enable a greater number of concurrent communications in a unit area in compliance with the current protocol design. The method comprises equipping nodes with wider neighborhood information than what is obtained with IEEE 802.11, and with a device calibration that equips the device with the knowledge of its performance in the presence of interference. The present disclosure medium access mechanism increases the aggregate throughput with every additional concurrent communication that is enabled in the shared medium. Cocktail Party-capable devices can fairly coexist with 802.11 legacy DCF devices, and co-operate with these devices in the same network without changes to those devices or to the standard. The same or similar mechanisms can be applied to other systems and standards in order to enable concurrent communications in the same contention area.
