The burstiness of multimedia traffic and the long propagation delays in Geosynchronous (GEO) satellite systems call for an efficient Medium Access Control (MAC) protocol and an equally efficient Call Admission Control (CAC) scheme, in order to provide acceptable Quality of Service (QoS) to multimedia users. This paper proposes a fair and dynamic CAC and MAC framework, named Fair Predictive Resource...
In this paper we explore, via an extensive simulation study, the performance of a medium access control (MAC) protocol when integrating high-quality video, Web and MP3 data packet traffic over a wireless picocellular system of very high capacity, with errors and capture. Mobile terminals are considered to be high performance devices with extended storage capabilities which can act like cache memories...
The provision of acceptable Quality-of-Service (QoS) for multimedia traffic over a geosynchronous earth orbit (GEO) satellite network demands the existence of a well-designed Medium Access Control (MAC) protocol. This paper proposes a new dynamic satellite bandwidth allocation technique which is based on accurate MPEG-4 videoconference traffic prediction. The use of the prediction in our protocol...
Powerline communications (PLC) are currently being considered as an alternative for high-speed data communications and Internet access. With multiple outlets in almost every room, power lines are already the most pervasive network in the home or small office. This work presents a new medium access control (MAC) protocol for the "last mile" access PLC networks. Via an extensive simulation...

The provision of acceptable quality-of-service (QoS) for integrated multimedia traffic over a geosynchronous earth orbit (GEO) satellite network demands the existence of a well-designed medium access control (MAC) protocol. This paper proposes a new dynamic satellite bandwidth allocation technique (predictive resource reservation access, PRRA) which is based on accurate videoconference traffic prediction...

An efficient Medium Access Control (MAC) protocol is critical for the performance of a Wireless Sensor Network (WSN), especially in terms of energy consumption. In this short paper which presents our work-in-progress we discuss the efficiency of S-MAC, a well-known MAC protocol for WSNs, and propose an improvement on the protocol. Via an extensive simulation study considering the cases of both a simple...
