Call admission control for wireless personal communications
Call admission control (CAC) in future wireless personal communication systems is to simultaneously achieve quality-of-service satisfaction and high resource utilization. It poses significant technical challenges due to scarce radio spectrum, user mobility, hostile wireless propagation environment, end-to-end connectivity, and dynamic nature of multimedia traffic. This paper aims at providing a...
متن کاملSoft QoS in Call Admission Control for Wireless Personal Communications
In wireless multimedia communication systems, call admission control (CAC) is critical for simultaneously achieving a high resource utilization efficiency and maintaining quality-of-service (QoS) to mobile users. User mobility, heterogeneous nature of multimedia traffic, and limited radio spectrum pose significant challenges to CAC. QoS provisioning to both new calls and handoff calls comes wit...
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 کاملCall admission control for voice and data traffic in wireless communications
Call admission control (CAC) in multimedia wireless communications is to guarantee quality of service (QoS) to mobile users and to achieve a high resource utilization ef®ciency. It is a challenging issue due to user mobility, limited radio spectrum, heterogeneous nature of multimedia traf®c. This paper proposes a CAC policy for a wireless system supporting both constant-rate voice calls and ava...
متن کاملCall admission control for non - uniform tra c in wireless
A distributed call admission control scheme is proposed for non-uniform traac in wireless networks. The proposed scheme uses the collective movement information of mobile terminals to estimate the handoo probabilities. Mobile terminal handoo history data is used as movement information. The performance of the scheme was evaluated by computer simulation. Introduction: Wireless network systems ar...
