The following topics are dealt with: quality of service; overlay and peer-to-peer networks; data centers and energy saving; scheduling, resource management, queue management, admission control; wireless ad hoc, mesh, and sensor networks; measurement, evaluation, adaptation and verification; and energy saving and quality evaluation metrics and methodologies.
Topology control and energy saving is one of the most important challenges in wireless ad hoc sensor networks. There are two approaches for conserve energy in topology control algorithms. First by adjusting a node??s transmission power and second manipulating a node??s state. In this paper, multi-state k-fault tolerant topology control algorithm is presented using clustering technique to manage k...
Supporting multimedia quality of service (QoS) is a necessary and critical requirement for next generation wireless networks. Wireless Mesh Networking is envisioned as an economically viable paradigm and a promising technology for supporting multimedia QoS. The non-mobile mesh routers with the capability of having less-constrained transmission power are the distinct characteristics for this type of...
The following topics were dealt with: wireless sensor networks; MANET; WLAN; IEEE 802.11; MIMO; OFDMA; scheduling; mobility and resource management; Internet; localization; WiMax; coding; OFDM; media streaming; QoS; security; WiMob; cryptographic protocols; ad hoc networks security; broadband wireless access; wireless and mobile computing.
Traffic and channel-data rate combined with the stream oriented methodology can provide a scheme for offering optimized and guaranteed QoS. In this work a stream oriented modeled scheme is proposed based on each nodepsilas self-scheduling energy management. This scheme is taking into account the overall packet loss in order to form the optimal effective -for the end-to-end connection- throughput response...

The design of an efficient medium access control (MAC) for wireless ad hoc networks or wireless sensor networks is challenging. These kinds of network can benefit from communication protocols that avoid frame collision: time division multiple access (TDMA). However, ad hoc networking and sensor networks enable novel communication paradigms which require the definition of new quality-of-service (QoS)...
This paper explores the attributes, layering models and objective functions in cross layer designs for mobile ad hoc wireless networks by taking all the statistical characteristics and constraints from the physical (PHY) layer, media access control (MAC) layer and network (NET) layer into consideration. This paper reviews the entire network optimization across all the PHY/MAC/NET layers. At the PHY...

Scheduling plays an important role in providing quality of service (QoS) support to multimedia communications in various kinds of wireless networks, including cellular networks, mobile ad hoc networks, and wireless sensor networks. The authors propose a scheduling algorithm at the medium access control (MAC) layer for multiple connections with diverse QoS requirements, where each connection employs...
