“…We performed throughput analysis for both cases (A) and (B). The results are exhibited in Table 2, together with those for the 2-Cell Algorithm in [13]. Table 2, we notice that the throughput of the 3-cell algorithm degrades gracefully in the presence of feedback errors.…”

“…The LSRAH class includes protocols which use as a core some Limited Sensing Random Access (LSRA) protocol [13], in hybrid combination with usually some variation of the same protocol. The LSRA class requires that a user be monitoring consecutive channel feedbacks, from the time that he generates a request for signaling to the time that his signaling is successfully transmitted, a requirement feasible in the wireless environment via carrier sensing on the corresponding signaling channel.…”

We present and evaluate a class of signaling protocols for wireless digital networks. The presented signaling protocols are stable, they induce good delay characteristics and they possess resistance to feed back errors. We also evaluate a system deploying the IEEE 802.11 as a signaling protocol, instead. In the presence of relatively tight admission delay constraints in signaling, the latter is significantly inferior to our proposed signaling technique. As the above admission delay constraints diminish, the IEEE 802.11 MAC protocol breaks down, while our proposed signaling technique maintains its high performance characteristics.

“…Video requirements change frequently over time and it is impossible to ensure that their demands will reach the BS successfully if we use techniques similar to the ones described in [13]. The two-cell stack reservation random access algorithm [14] is used to resolve the collisions, among video request packets. After the end of the video contention period, ftp terminals without a reservation and with sessions ready for transmission, begin their contention in order to reserve information slots.…”

“…After the end of the video contention period, ftp terminals without a reservation and with sessions ready for transmission, begin their contention in order to reserve information slots. In the case that two or more ftp request packets collide, the two-cell stack random access algorithm [14] is used to resolve the collision, due to its operational simplicity, stability and high throughput compared to PRMA [15]. Video and data terminals do not exhaust their attempts for a reservation within the request intervals.…”

In this paper we propose and evaluate a Medium Access Control (MAC) protocol for the efficient integration of high quality video traffic with ftp data packet traffic over a wireless cellular channel of very high capacity. We envision a system where the mobile terminals are considered to be high performance devices with extended storage capabilities which can act like cache memories streaming multimedia material. Via an extensive simulation study we evaluate the system's performance under a variety of possible loads which consist of actual MPEG-4 streams and ftp sessions, and we show that our scheme outperforms another, well-known MAC protocol for cellular networks.

In this paper, we present an effective mechanism for scheduling and traffic policing in 4th generation wireless networks. More specifically, we: a) extend our previous work on a Multiple Access Control (MAC) scheme for the multiplexing of voice, video and bursty data traffic over a very high-speed wireless TDMA channel, and we study our scheme's performance when MPEG-4 videoconference users of various traffic characteristics are present in the system, and b) we combine the MAC mechanism with an improved version of an efficient traffic policing mechanism. Our results are derived for cases with and without handoff traffic in the uplink channel, and it is shown that although the burstiness of MPEG-4 traffic and channel errors impedes the maximization of channel throughput, our scheme still achieves high channel throughput for all the combined voice/video/data loads examined.
