Limited battery life has become a critical issue, particularly when mobile devices run multimedia applications, for which users have high quality expectations. In this paper, we propose a cross-layer quality-oriented energy-efficient multimedia delivery scheme (Q-PASTE), which balances the need for the following: increased energy efficiency/battery lifetime and high user quality of experience. The...
The LTE “Long Term Evolution” technology was introduced to reduces the DATA network latency, in addition to provide higher data throughput. But the nature of LTE prohibits the transmission of voice related services. VoLTE “Voice over LTE” is a solution to transfer voice packets with special treatment over the LTE network, and get benefits from its low latency and quality of services capabilities to...
Long Term Evolution (LTE) as an evolution of fourth generation (4G) technology offers high data rate of upto 100 Mbps for data applications. But it lacks native support for Circuit Switched (CS) voice service which has been the main revenue generator for operators. This introduces the problem of how to provide voice call when a user is in LTE and how to ensure voice call continuity when it moves out...
Telecom based service providers are relentlessly trying to accelerate their service offerings to match the pace at which the users are embracing the Web. In reality IMS based Telecom and Internet based Web 2.0 networks have their own advantages and need to co-exist to create an enriched user experience. The convergence of IP Multimedia subsystem (IMS) based Telecom and Web 2.0 based networks is slowly...
The objective of the work is to propose a Quality of Service (QoS) aware heterogeneous networking model for emergency management system using network virtualization. An emergency management information system is made up of heterogeneous communication and computing networks to address the crisis situation and adopt the network according to the service parameters. To meet the unpredictable demands and...
Inter-enterprise collaborative environments and applications enable users to utilize and manage voice, data and video services on a common IP-based network. As voice moves from its traditional separate network to having both user and trunk connections traverse the corporate IP network, the demands for uptime and quality of experience increase dramatically. When video-over-IP is layered onto the same...
Existing solutions for building wireless mesh networks suffer from reduced efficiency. This is due to lack of reliable self-configuration procedures that can dynamically adapt to varying network conditions, lack of efficient and scalable end-to-end quality of service (QoS) support, and lack of generalized and seamless mobility support. Therefore, ensuring a certain level of QoS to mobile users is...
Applications on network need not only enough quality of service (QoS) but also enough quality of security service (QoSS) because the security is essential for most of applications on network. The purpose of QoSS is to organize various security services together to achieve enough security for applications. As security requirements vary dramatically for different applications, differentiated security...
