Cognitive Radio (CR) is an intelligent radio that can dynamically access the radio spectrum. Secondary users in Cognitive Radio Network (CRN) can access the licensed spectrum without causing harmful interference to primary users. The performance of cognitive radio networking functionalities depends on the properties of the spectrum band in use. This necessitates a crosslayer design in the entir...

A Syndicated Show in a Network World: Frederic Ziv’s Favorite Story Christine Becker Journal of Radio Studies (Summer 2001): 160-174. Abstract: Across his career as one of the most successful producers of syndicated radio and television programming, Frederic W. Ziv continually battled against network domination. Forced to operate under constraints which resulted from network monopolistic practi...

Advances in medical sciences with other fields of science and technology is closely casual profound mutations in different branches of science and methods for providing medical services affect the lives of its descriptor. Wireless Body Area Network (WBAN) represents such a leap. Those networks excite new branches in the world of telemedicine. Small wireless sensors, to be quite precise and calc...

In a composite radio environment, different wireless access technologies can be co-operating components of a combined heterogeneous infrastructure. The exploitation of a wireless system, operating in a composite radio context, requires upgraded service and network management capabilities. This paper presents an integrated management system and gives evidence of its capability of optimising serv...

In the paper an original method of the UMTS radio network design was presented. The method is based on simple way of capacitycoverage trade-off estimation for WCDMA/FDD radio interface. This trade-off is estimated by using universal load characteristics and normalized coverage characteristics. The characteristics are useful for any propagation environment as well as for any service performance ...

This chapter describes the functions of a system proposed for the music hit recommendation from social network data base. This system carries out the automatic collection, evaluation and rating of music reviewers, the possibility for listeners to rate musical hits and recommendations deduced from auditor’s profiles in the form of regional internet radio. First, the system searches and retrieves...

The first result is on the separability of the unicast capacity of stationary multi-channel multi-radio wireless networks, i.e., whether the capacity of such a network is equal to the sum of the capacities of the corresponding single-channel singleradio wireless networks. For both the Arbitrary Network model and the Random Network model, given a channel assignment, the separability property doe...

OF THE DISSERTATION Algorithms and LP-Duality Based Lower Bounds in Ad-hoc Radio Networks by Rohan Jude Fernandes Dissertation Director: Mart́ın Farach-Colton An Ad-hoc Radio Network consists of nodes with no knowledge of its neighbors and knowledge of its own ID and n, the size of the network. In this thesis, we present algorithms and lower bounds related to ad-hoc network initialization. Senso...

System aspects of smart antenna (SA) technology in wireless communications such as SA receiver structure and algorithms, wireless network control and network planning are discussed. A classification of SA receivers and their algorithms is given in order to simplify orientation in very large amount of the proposed types. Several radio network planning and upgrading concepts with SA are evaluated...
