Abstrcrct-When designing the call admission control algorithm for multi-traffic mobile communication system, two priorities must be taken into account: one is the priority between the traffics; other is the priority for handoff call. I n this paper, an analytical model, a two-dimension Markov chain is proposed to investigate the performance of the call admission control scheme, which is based o...

In this paper, a call admission control scheme based on user position information is proposed in the context of CDMA2000 and WLAN heterogeneous networks with voice and data traffic. The user position based call admission (UPBAC) scheme is composed of a parameter measurer, an admission controller and a decision executer. When a new call or a handoff call arrives, the parameter measurer first obt...

We formulate the call admission control problem for a single link in an integrated service environment as a Markov Decision Problem. In principle , an optimal admission control policy can be computed using methods of Dynamic Programming. However, as the number of possible states of the underlying Markov Chain grows exponentially in the number of customer classes, Dynamic Programming algorithms ...

In this paper, we derive stochastic performance bounds under the assumption of exponentially bounded burstiness (EBB) traffic model and exponentially bounded fluctuation (EBF) channel model. Then we propose a measurement-based call admission algorithm providing statistical service level agreement (SLA) guarantee for accepted flows based on the QoS prediction equations for both single and multip...

A Multi-agent System can be defined as a set of agents that interact with each other and with the environment to solve a particular problem in a coordinated (behaviorally coherent) manner. Our paper models Call Admission Control in Cellular networks as Multi Agent resource provisioning problem to provide Service Level Agreement (SLA) in wireless cellular network. For which we modify SHUFFLE mod...

Call admission control in a wireless cell in a personal communication system (PCS) can be modeled as an M/M/C/C queuing system with m classes of users. Semi-Markov Decision Process (SMDP) can be used to optimize channel utilization with upper bounds on handoff blocking probabilities as Quality of Service constraints. However, this method is too time-consuming and therefore it fails when state s...
