Energy conservation is a critical issue regarding wireless mobile ad hoc networks, since the nodes are battery restrained and the depletion of their power defines the lifetime of the network. In this… (More)
Admission Control (AC) algorithms in mobile cellular networks support continuity of active communication sessions by guaranteeing availability of free resources. In this paper, we first describe the… (More)
The adaptive modulation and coding AMC technique, which has been adopted by advanced mobile telecommunication systems, supports a flexible response to the random radio behaviour. As a result, the… (More)
The Call Admission Control (CAC) method presented in this paper is based on the statistical properties of the network’s traffic variables. It probabilistically estimates the time until the release of… (More)
Advanced mobile communication systems have adopted the adaptive modulation and coding technique because it enables efficient use of the scarce radio resources. The resultant time-varying resource… (More)
In this paper we consider call admission control in cellular environment for data sessions and voice calls of high priority. A cell is divided into two zones with different average signal to noise… (More)
