Stability Analysis for Communication of Voice Terminals with Packet Reservation Multiple Access Protocol with High Propagation Delays using State Estimation
This paper addresses stability, bifurcation properties, and performance improvement of the packet reservation multiple access with hindering states (PRMA-HS) protocol, a medium access control scheme suitable for application in low earth orbit mobile satellite systems. The bistable behavior and bifurcation properties of the PRMA-HS protocol for a traffic with voice sources is investigated. A bifurcation control scheme using state estimation is proposed to increase the capacity of the PRMA-HS protocol, defined as the number of simultaneous users sharing the same communication medium. Finally, a brief discussion concerning the extension of the proposed bifurcation control to PRMA-HS protocol over a random packet error channel is also provided.
