One or more mobile nodes with mobile router(s) form a mobile network. Mobile router acts as the single point of attachment to the internet. As the configuration of mobile network changes, mobile router keeps track of its registered mobile nodes. Presently, a scheme has been designed for group registration of mobile nodes under a single home agent. In this paper, a communication scheme is proposed...
A new remote server based gaming approach, where the responsibility of executing the gaming engines is put on remote servers instead of the mobile devices, has the potential for enabling mobile users to play the same rich Internet games available to PC users. However, the mobile gaming user experience may be limited by risks of unacceptably high response time, and low gaming video quality, as gaming...
With its comprehensive QoS support and ubiquitous coverage, the mobile WiMAX network offers promising opportunities for unwiring the last mile connectivity to Internet. However, stringent QoS demands of multimedia applications entail studies on service-oriented radio resource management. This article systematically examines the design issues and the state of the art of multimedia downlink scheduling...
The next generation broadband wireless access networks are expected to support a variety of multimedia rich applications which can lead to very high traffic demand. With the development of high speed radio access technologies the backhaul network can become the bottleneck if not upgraded and configured optimally to support the expected increase in date rates and traffic demands. To deliver high data...
Network mobility (NEMO) basic support protocol is an extension mobile IPv6. NEMO signaling is performed with extended mobile IPv6 messages. NEMO basic support protocol is concerned with managing the mobility of an entire network, it provides for devices or vehicles which move to another point of attachment to the Internet. NEMO can maintain sessions established nodes between the mobile network and...
Numbat is a new simulation environment, developed with IPv6 mobile stations supporting WiMAX in mind. To provide near real-time capabilities (required for VoIP or video streaming) in a mobile environment, full handover procedure has to be as fast as possible. Both investigated components - IEEE 802.16 based networks and IPv6 capable nodes - are rapidly gaining acceptance. Therefore it appears essential...
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...
