“…In both our proposed scheme and the "ideal" one, in the rare case when the abandoned slots of a video user (user A) are allocated to a user B (video or data), which in turn enters a bad state after a while, the abandoned slots are not further allocated to other users; they are "returned" to user A, in order not to increase system complexity with consequent "loans" of the same slots to multiple users. We also compare the enhanced MI-MAC with an efficient MAC protocol recently proposed in the literature [17]. The authors in [17] design a MAC protocol for wireless cellular networks which is based on PRMA but is focused on the transmission of multimedia traffic (video, voice and data, as in the enhanced MI-MAC).…”

“…The first important difference of our scheme with [17] is that in [17] a fixed number of slots are dedicated in each frame to video traffic; the authors' work focuses in part on finding an "optimal" number of slots for the single video user. It is clear that, due to the burstiness of video traffic, even with a very good choice for the number of slots dedicated to the video user, in many frames this choice will lead to the loss of valuable bandwidth, when video users happen to be transmitting at a lower rate.…”

In recent work (Koutsakis et al., IEEE Trans Veh Technol 54(5):1863-1874, 2005, we have introduced multimedia integration multiple access control protocol (MI-MAC). The protocol was shown to achieve superior performance in comparison to other protocols of the literature when integrating various types of multimedia traffic over wireless cellular networks. In this work we enhance the scheduling scheme of MI-MAC by adding three important parameters into its study. These are: (a) the handling of handoff traffic, (b) per user varying channel conditions in the uplink and downlink channels and (c) video sources' contention for channel resources. These parameters are added in order to evaluate the protocol under a significantly more realistic wireless cellular network scenario. New scheduling ideas are proposed in order to efficiently incorporate the new parameters into the scheme. The evaluation, conducted by comparing the enhanced MI-MAC with another efficient protocol of the literature and with an "ideal" MAC protocol, focuses on the efficient transmission of MPEG-4 video traffic and shows that our scheme achieves excellent performance results.

“…Indicatively, we mention here that the use of either [38] or [39] in the simulations conducted in this paper leads to a 9% and 13.5% lower throughput, respectively, on the average, over all the studied scenarios in which the two schemes can provide the required QoS for telemedicine traffic. These scenarios are the ones in which the telemedicine traffic load and the regular video traffic load are both low.…”

Abstract-Telemedicine traffic carries critical information with regard to a patients' condition; hence, it requires the highest transmission priority compared with all other types of traffic in the cellular network. The need for expedited errorless transmission of multimedia telemedicine traffic calls for a guaranteed bandwidth to telemedicine users. This condition, however, creates a tradeoff between the satisfaction of the very strict quality-of-service (QoS) requirements of telemedicine traffic and the loss of this guaranteed bandwidth in the numerous cases when it is left unused due to the infrequent nature of telemedicine traffic. To resolve this complex problem, in this paper, we propose and combine the following two techniques: 1) an adaptive bandwidth reservation scheme based on road map information and on user mobility and 2) a fair scheduling scheme for telemedicine traffic transmission over wireless cellular networks.

“…In the contention-based scheme [5][6][7][8] reducing the collision probability and the size of control packet is necessary to reduce wastage of bandwidth in case of collision. On the other hand, the contention-free scheme [9][10][11][12] is based on either a piggyback mechanism, which piggybacks the dynamic parameters on the uplink data burst, or polling mechanism, which dynamically assigns an uplink dedicated slot for transferring the dynamic parameters.…”

The major issue related to the realization of wireless multimedia system is the design of suitable medium access control (MAC) protocol. The design challenge is to maximize the utilization of the limited wireless resources while guaranteeing the various quality of service requirements for all traffic classes especially for the stringent real-time constraint of real time variable bit rate (rt-VBR) video service. In this paper a novel resource allocation algorithm for video traffic is proposed. The proposed allocation algorithm aims to provide fair delay for video packets by minimizing the delay difference among transmitted video packets. At the same time it adaptively controls the allocated resources (bandwidth) for video traffic around the corresponding average bit rate, and has the ability of controlling the quality of service (QoS) offered for video traffic in terms of packet loss probability and average delay. A minimized control overhead of only two bits is needed to increase the utilization efficiency. Simulation results show that the proposed algorithm achieves very high utilization and provides nearly fair delay among video packets. Its efficiency is also investigated under traffic integration condition with voice and data traffic to show that the QoS offered to video traffic does not change in the presence of the highest priority voice traffic while data traffic increases the channel utilization to 98% by using the remaining bandwidth after voice and video traffic while a good QoS is offered to voice and data traffic.
