This paper studies two problems in secondary spectrum access with minimum signal to interference noise ratio (quality of service (QoS) guarantee under an interference temperature constraint and proposes a centralized reduced complexity search algorithm to find the optimal solution.
Reliable Multimedia Transmission Over Cognitive Radio Networks Using Fountain Codes
This paper proposes a technique for distributed multimedia transmission over the secondary user network, which makes use of opportunistic spectrum access with the help of cognitive radios and uses digital fountain codes to distribute the multimedia content over unused spectrum.
Standardization and research in cognitive and dynamic spectrum access networks: IEEE SCC41 efforts and other activities
Possible future standardization topics for IEEE SCC41 are outlined, in the framework of other related standardization activities, and open research issues that present future challenges for the standardization community are discussed.

The proposed framework takes into account communication, computation, and compilation energies to decide where to compile and execute a method, and how to execute it, and it is revealed that the proposed techniques are very effective in conserving the energy of the mobile client.
Image Steganography and Steganalysis: Concepts and Practice
It is shown how conventional definitions do not really adequately cover image steganography and an alternate definition is provided to provide alternate definition.
