The mobile ad hoc networks (MANET) technology is a self organized wireless interconnection of communication devices without the use of any fixed network infrastructure/backbone. The performance of Ad-hoc On-demand Distance Vector (AODV) and Dynamic Source Routing (DSR) protocol are two MANET protocol. This paper presents the performance analysis comparison of ad-hoc on-demand routing protocol (AODV)...
In the recent years Cognitive Radio (CR) technology imposed itself like a very good solution to the increasing spectrum utilization. This technology proposes the development of a new radio type - a cognitive radio - endowed with intelligence that shall sense, share, and use the spectrum opportunities (SOP) of the preexisting wireless networks, that is the channels that are not used by the licensed...
The cognitive radio (CR) technology was proposed as a solution for the lack of wireless resources in an environment with a rapidly growing number of users. The CR advances the dynamic utilization of the licensed users' unused spectrum channels by secondary users. The paper looks into large CR networks by proposing two improved variants of IPSAG (IP Spectrum Aware Geographic routing algorithm). The...
There has been a rapid growth of services based on session control. Session-based services comprise multimedia conferences, Internet telephone calls, instant messaging, and similar applications consisting of one or more media types such as audio and video. Deployment examples include session control services as part of the IP multimedia subsystem (IMS), in the third-generation mobile networks. High...
