Adaptive Admission Control in Mobile Cellular Networks with Streaming and Elastic Traffic
نویسندگان
چکیده
We propose a novel adaptive reservation scheme that handles, in an integrated way, streaming and elastic traffic. The scheme continuously adjusts the quality of service perceived by users, adapting to any mix of traffic and enforcing a differentiated treatment among services, both in fixed and variable capacity systems. The performance evaluation carried out verifies that the QoS objective is met with an excellent precision and that it converges rapidly to new operating conditions. Other key features of our scheme are its simplicity and its oscillation-free behavior.

Maximizing the capacity of mobile cellular networks with heterogeneous traffic
We propose a novel adaptive reservation scheme that handles, in an integrated way, heterogeneous traffic of two types: streaming and elastic. The scheme adjusts the rates of streaming sessions to meet the QoS objective, adapting to any mix of traffic and enforcing a differentiated treatment among services, in both fixed and variable capacity systems. The resource utilization achieved by streami...
متن کاملAdaptive call admission control and resource allocation in multi server wireless/cellular network
The ever increasing demand of the subscribers has put pressure on the capacity of wireless networks around the world. To utilize the scare resources, in the present paper we propose an optimal allocation scheme for an integrated wireless/cellular model with handoff priority and handoff guarantee services. The suggested algorithm optimally allocates the resources in each cell and dynamically adj...
متن کاملAdmission control for differentiated services in 3G cellular networks
Third generation wireless systems can simultaneously accommodate flow transmissions of users with widely heterogeneous applications. As radio resources are limited, we propose an admission control rule that protects users with stringent capacity requirements (“streaming traffic”) while offering sufficient capacity over longer time intervals to delay-tolerant users (“elastic traffic”). Using tim...
متن کاملAn Adaptive Congestion Control Mechanism for Streaming Multimedia in Mobile Ad-hoc Networks
In mobile ad hoc networks, most of the present routing protocols are designed to have congestion aware, but not congestion adaptive. The way in which the congestion is handled results in longer delay and more packets to be lost for streaming multimedia. When a new route is needed, the routing protocols require a significant overhead in finding it. Mobile Ad hoc Networks shows unexpected behavio...
متن کاملA Two-Threshold Guard Channel Scheme for Minimizing Blocking Probability in Communication Networks
In this paper, we consider the call admission problem in cellular network with two classes of voice users. In the first part of paper, we introduce a two-threshold guard channel policy and study its limiting behavior under the stationary traffic. Then we give an algorithm for finding the optimal number of guard channels. In the second part of this paper, we give an algorithm, which minimizes th...
