Quality of Service (QoS) is defined as the capability of network elements (e.g. application, host and router) to provide some sort of assurance and service differentiation for consistent network data delivery. Recently, Internet Engineering Task Force (IETF) has introduced Network Mobility Basic Support (NEMO BS) protocol (RFC 3963) to address the challenges of the entire network mobility (such as...
Call Detail Records (CDR) is a valuable source of information; it opens new opportunities for telecom industry and maximize its revenues as well as it helps the community to raise its standard of living in many different ways. However, we need to analyze CDRs in order to extract its big value. But CDRs has a huge volume, variety of data and high data rate, while current telecom systems are designed...
Registration delay is a significant issue for mobile network due to increase traffic load with handoff latency at the time of frequent movement from one subnet to another of Mobile Router (MR) in NEMO Basic Support protocol (NEMO BSP). Hence, a network-based localized protocol (i.e. PMIPv6) is integrated with NEMO in order to solve these matters. Yet, combining this network-based localized protocol...
Recently, wireless devices have been used significantly due to the continuous and enormous Services that they provide. One of the major challenges that faces is how to achieve high network performance. The Internet Engineering Task Force (IETF) has developed Mobile IP, which allows Mobile node to be connected while it is moving as well as functioning in foreign mobile network zone using its original...
Recently wireless mesh networks (WMNs) gained significant roles in the current communication technologies and have been used in numerous applications such as transportation systems, rescue systems, Surveillance systems, community and neighborhood networking and etc. Therefore, many researchers pay their attention to the wireless mesh network issues especially the gateway placement optimization problems...
The provision for addressing multiple destinations in group multimedia application delivery over Wireless Mesh Networks (WMN) can be achieved efficiently via multicasting while considering the mobility of Mesh Clients (MC). One of the prominent components of WMN is the Internet Gateway (IGW) which provides wired bridge connection between the backbone network and the Internet. In addition, its cost...
Recently, the necessity of applications where many users have to interact in a close manner over mobile Ad-Hoc networks gains high popularity. Multicast communication is essential in this type of applications to reduce the overhead of group communication. For group-oriented multimedia applications Quality of Service (QoS) provision is a basic requirement, which makes an efficient QoS multicast routing...
The increasing privacy risks associated with the recent growth of multimedia streaming applications raised a big industry demand for secure and efficient stream cipher. The fact that stream ciphers do not expand messages, and tolerant to bit-errors, make it highly desirable for many communication applications. During the last one and half decade several cryptosystems have been put forward, many of...
