The rapid spread of IP-based Access technologies and the move towards Core Network Convergence with IMS has led to an explosion in multimedia content delivery across packet networks. IMS provides mobile and multimedia services to the customer along with fixed networks support leading to mobile and fixed convergence. The use of open standard IP protocols,(More)
The mobile industry is evolving rapidly and new mobile devices with sophisticated capabilities are released almost every day. The hacking technologies and/or methodologies have also evolved and a single security solution cannot address all the security threats and vulnerabilities. To provide a strong security mechanism a combination of solutions need to be(More)
Grid is already being successfully used in many scientific applications where huge amounts of data have to be processed. The popularity of grid has almost increased exponentially with wide spread adoption of cloud computing. However mobile grid still is in its infancy and considerable research is going towards developing a framework that can reap the full(More)
The rapid spread of IP-based access technologies as well as the move towards core network convergence with IMS has led to an explosion in multimedia content delivery across packet networks. Although this transition has led to a much wider and richer service experience, there is also increased concern related to media protection and secure delivery of(More)
Convergence is a hot topic in the communication industry. The wide spread popularity of IP Multimedia Subsystem (IMS) is a clear indication that independent networks will be integrated into a single IP-based infrastructure referred to as Next Generation Networks (NGN) in the near future. The services, network architectures and traffic pattern in NGN will(More)
To help you address contemporary challenges, the text details a conceptual framework that provides modeling facilities for context-aware, multi-channel Web applications. It compares various platforms for developing mobile services—from the developer and user perspectives—and explains how to use high-level modeling constructs to drive the application(More)
Traditionally SNMP has been the preferred protocol for Management in older generation packet networks like Ethernet, Token-ring etc. Efficient, low-bandwidth transport mechanisms (UDP over IP) as well an optimized, but limited, data model were the 2 main reasons for its popularity. The simplistic data model architecture used by SNMP (a flat MIB definition)(More)
Most service and content providers are opening up their services by publishing the interfaces for using the service. This promotes usage of the service and the development of new services by meshing up services from multiple service and content providers. In a competitive market scenario, there are two approaches that can be adopted in providing a service(More)
