In Long Term Evolution (LTE) Networks, several call admission control mechanisms were proposed. They take into account some network constraints such as service diversity and availability of radio resources. However, the shortcomings of the existing mechanisms led us to propose a new approach called Efficient Bandwidth Call Admission Control (EB_CAC). Our proposition considers the quality of service...
This paper introduces a new call admission control (CAC) mechanism for Long Term Evolution (LTE) networks supporting multimedia services with different classes of traffic. Our CAC mechanism classifies calls into real time and non-real time users, then estimates the channel quality based upon the received signal strength (RSS) value, and finally identifies the call as either new call (NC) or handoff...
Due to recent advances in wireless technologies, wireless mesh networks (WMNs) are expected in the near future to fully handle content-rich multimedia services with various quality of services (QoS) guarantee. Unlike traditional data applications, multimedia applications require QoS support in order to satisfy the user's service requirements. Admission control has been advocated as a promising approach...
