Cognitive Radio-Based Power Adjustment For Wi-Fi.
In this paper the idea of using Cognitive Radio (CR) techniques to optimize the access point (AP) configuration for
IEEE 802.11 WLAN was exploited. In particular, we address the issue of optimizing AP transmission power and channel allocation within the network
Bandwidth Management for Intranets Using Multicast Firewalls
Multimedia applications utilizing multicast transmission techniques are becoming prevalent as the number of users and types of applications proliferate. Nonetheless, the deployment of such applications throughout an Intranet is constrained by the lack of multicast capable routers and the inability to protect the network from being swamped by multicast

A Scalable QoS Scheduling Architecture For WiMAX Multi-Hop Relay Networks.
WiMAX Mobile Multi-hop Relay (MMR) network has been introduced to increase the capacity and extend the
coverage area of a single WiMAX Base Station (BS) by the use of a Relay Station (RS)
Statistical Analysis of Video Frame Size Distribution Originating from Scalable Video Codec (SVC)
Designing an effective and high performance network requires an accurate characterization and modeling of network traffic.The
modeling of video frame sizes is normally applied in simulation studies and mathematical analysis and generating streams for
testing and compliance purposes. Besides, video traffic assumed as a major source of multimedia traffic in future heterogeneous
network. Therefore, the statistical distribution of video data can be used as the inputs for performance modeling of networks. The
finding of this paper comprises the theoretical definition of distribution which seems to be relevant to the video trace in terms of
its statistical properties and finds the best distribution using both the graphical method and the hypothesis test.The data set used
in this article consists of layered video traces generating from Scalable Video Codec (SVC) video compression technique of three
different movies
Survey And New Approach In Service Discovery And Advertisement For Mobile Ad Hoc Networks.
Service advertisement and discovery is an important component for mobile adhoc communications and collaboration in ubiquitous computing environments. The ability to discover services offered in a mobile adhoc network is the major prerequisite for effective usability of these networks. This paper aims to classify and compare existing Service Discovery (SD) protocols for MANETs by grouping them based on their SD strategies and service information accumulation strategies, and to propose an efficient approach for addressing the inherent issues
Control and Media Sessions: lAX with RSW Control Criteria
This paper discusses technical issues related to
delivery and control of IP multimedia services, such as
multimedia conferencing, involving heterogeneous end
terminals. In particular, it proposes the design of an
experimental system for interworking between InterAsterisk
eXchange Protocol and RSW session and call control signaling
protocols
