Dynamic sessions control for multimedia distributed systems
Zheng Wu · 2002
A dynamic sessions control algorithm for multimedia distributed systems is presented in this paper. The algorithm is theoretically based on a "demand and supply" economic model and specifically on "Pareto efficient allocation". In this mechanism, users compete for resources selfishly and attempt to get maximal benefit while resources are not only utilised efficiently, but also allocated in a such way that users with diverse Quality of Services (QoS) requirements achieve individual optimality. The algorithm includes a session renegotiation function which is used to reduce the blocking probability of calls significantly. Finally, the simulation results of the algorithm are demonstrated and discussed.
