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...
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 multimedia traffic over a geosynchronous earth orbit (GEO) satellite network demands the existence of a well-designed Medium Access Control (MAC) protocol. In this short paper which presents our work-in-progress, we propose a new dynamic satellite bandwidth allocation technique which is based on accurate videoconference traffic prediction, and...
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 work 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 simple and complicated topologies, the enhanced...
A new scheme, combining medium access control (MAC) with traffic policing for next generation wireless networks, is proposed in this work, in order to provide a flexible solution for the integration of multimedia traffic over noisy high capacity links. The most attractive features of our scheme are: a) its flexibility, which allows it to adapt easily to wireless channel of various capacities, and...
