Abstract

Bandwidth allocation configuration and fully decentralized adaptive medium access control (AMAC) systems and methods with support for time critical applications, spectrum efficiency, scalability enhancements, and fair allocation of bandwidth among nodes sharing a common channel. The methods fully integrate TDMA and CSMA/CA channel access approaches and incorporate adaptive congestion and collisions avoidance scheme to reduce bandwidth wastage and diminish adverse cross layers interactions. AMAC improves support for multi-media traffic while allowing higher transmission incidents from large number of transmitting devices sharing a common channel, with fair distribution of the available bandwidth, to enable improved multi-level-security connectivity over a common multi-hop wireless network, provide end-to-end performance enhancement for constant bit rate traffic, variable bit rate traffic, and distribute bandwidth fairly amongst competing TCP traffic flows that traverse varying length paths in multi-hop ad-hoc wireless networks.
