“…In the literature [14][15][16][17][18], the majority of DiffServ mechanisms are proposed for wireless multimedia sensor networks (WMSN), and can be classified according to various types of criteria, such as drive-mode-aware criteria, QoS-aware criteria, and other criteria. In references [15,16], the services are differentiated based on drive modes,…”

“…From this point of view, NC-NET can also be investigated as a special form of ad hoc network. In previous literature, several effective technologies for MAC protocols of ad hoc network have been studied in depth, and can be used as a reference for our research, i.e., directional antennas [9][10][11], multi-channel diversity [12], differentiated-service mechanisms [13][14][15][16][17][18], and cooperative communication [19][20][21][22][23][24].…”

Abstract:In this paper, a dynamic cooperative MAC protocol (DDC-MAC) based on cluster network topology is proposed, which has the capability of differentiated service mechanisms and long-range communication. In DDC-MAC, heterogeneous communications are classified according to service types and quality of service (QoS) requirements, i.e., periodic communication mode (PC mode) is extracted with a QoS guarantee for high-frequency periodic information exchange based on adapt-TDMA mechanisms, while other services are classified as being in on-demand communication mode (OC mode), which includes channel contention and access mechanisms based on a multiple priority algorithm. OC mode is embedded into the adapt-TDMA process adaptively, and the two communication modes can work in parallel. Furthermore, adaptive array hybrid antenna systems and cooperative communication with optimal relay are presented, to exploit the opportunity for long-range transmission, while an adaptive channel back-off sequence is deduced, to mitigate packet collision and network congestion. Moreover, we developed an analytical framework to quantify the performance of the DDC-MAC protocol and conducted extensive simulation. Simulation results show that the proposed DDC-MAC protocol enhances network performance in diverse scenarios, and significantly improves network throughput and reduces average delay compared with other MAC protocols.

MUSAQ: a multimedia session‐aware QoS provisioning scheme for cellular networks

Networked multimedia applications involve a set of cooperating streams that together form a multimedia session. Existing QoS provisioning schemes for multimedia applications in cellular networks either allow composite streams to compete with one another for resources or else provide QoS to a session as an atomic entity, leaving to the application the task of managing QoS for the individual streams. The main contribution of this work is to propose a novel local QoS provisioning scheme for cellular networks that is aware of the relationships between the streams that compose a session. Our new Multimedia Session‐Aware QoS (MUSAQ) provisioning scheme manages the QoS of the individual streams in a session, and, with the knowledge of their relationships, it prevents destructive competition between the streams. Further, by allowing application‐specified prioritization between streams in a session, MUSAQ features a significant improvement in performance over session‐unaware schemes.
