“…Different types of traffic are considered in multimediabased schemes-real-time versus non real-time [13,23,32,36,46,66,95] narrowband versus wideband [24] and [25], premium service versus assured service [97], voice versus data [49], voice versus data and video [70], voice versus text, audio, and video [34], voice versus interactive video, videophone, www and e-mail [31]. Some schemes dealing with multimedia traffic give higher priority to a specific call based on its class of traffic, for example, real-time over non real-time [13,23,32,46,50,66,95] and voice over data [68].…”

“…In distributed schemes, call admission is either performed in the current and its adjacent (neighbor) cells [12,60,66] or in a cluster of cells [3,34,47,103]. Oliveira et al [66] proposed a scheme that considers both local information and remote information to determine whether to accept or reject a connection.…”

Provision of seamless service to multimedia applications in cellular wireless networks largely depends on the way calls are handled during handoff. Hence, sufficient resources must be provided for handoff (HO) connections when a mobile station (MS) moves from one cell to another. Effective allocation of resources can be achieved when the exact future trajectory of MSs is known in advance. However, such a scenario is unrealistic. The next best possibility is to employ user mobility prediction to determine the cell(s) a MS will likely visit in the near future. In this paper, we present an extensive survey and classification of channel (bandwidth) reservation schemes which employ user mobility prediction in the resource reservation process. We also present a survey and classification of call admission control (CAC) schemes, including discussion of prioritized and non-prioritized handoff schemes, which can be useful for researches both in academia and industry.

“…C r c need to be reserved in each cell to ensure the continuity of ongoing services. Computing C r c is challenging and highly depends on road network configurations and geographical environments in addition to mobility parameters such as the MU's current position, direction, and speed as presented in [10,11,17]. However, in [6,7], it is investigated that the results with fixed reservation is similar to the adaptive reservation when only the fair bandwidth distribution and CAC scheme is considered.…”

SUMMARYDepending on the flexibility in controlling the transmission rate and the differences between on-line (real time) and off-line transmission modes, multimedia applications can potentially include a wide range of services, with the traditional stringent quality-of-service (QoS) requirement at the extreme to the highly adaptive ones that can tolerate or smartly adapt to the transient fluctuations in the QoS parameters. Keeping the cellular multimedia networks efficient with low call dropping and blocking rates and high bandwidth utilisation while maintaining a fair distribution of bandwidth by synergistically addressing the differences among these services remains a significant challenge. This paper addresses this issue by developing a novel min-max fairness scheme where bandwidth is distributed with equal share only after ensuring the minimum requirements. Besides borrowing in-use bandwidth through redistribution, this scheme also allows for using the reserved bandwidth for the offline services. Simulation results confirm the superiority of this scheme against the rate-based borrowing and the max-min fairness schemes, the two most recent works addressing similar issues.

“…Therefore, these kinds of approaches are not suitable for mobile environment because the mobility of the user in wireless networks is one of the most important features. Prediction of movements has been used to enhance the performance of the resource reservation, location management and handover management in mobile networks [17][18][19][20][21][22][23][24][25].
