Nowadays the widespread use of variety of smart phones and tablets with wide range of multimedia application support is driving more data service users towards full mobility causing a rapid increase in demand for mobile data rates. These new devices and multimedia applications require high data rates and reduced latency to provide better Quality of Service (QoS). To address these requirements 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...
LTE (Long Term Evolution) is becoming the fastest growing mobile communications technology ever. IEEE 802.11 and IEEE 802.15 standards is also developing on the other side. IEEE 802.11 standards (WLAN-Wireless Local area Network) provides higher data rates and less coverage. In the next generation networks, it is very important to increase the coverage area and efficiency of WLAN standards. Hence...
As we know in Mobile Ad hoc network our Nodes are highly mobile. They move around the Network. Due to this network topology and number of neighboring nodes in each node frequently change. Movement of nodes from one to another network also affect to the communication between them. As we know if nodes are within the range of each other they will work properly. But any of one node is not in the range...
The numbers of MVNOs (Mobile Virtual Network Operator) are growing globally, but so do their operational and business issues. This paper identifies these issues and looks for remedies via the new 4G architecture and interfaces. The paper examines the ‘Full’ MVNO model as a ‘Home’ network in a pseudo roaming scenario (National Roaming), allowing MVNO to connect to multiple MNOs through the discovery...
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...
Radio frequency identification (RFID) is a kind of electronic identification technology that is becoming widely deployed. Compared to traditional RFID system, tags in the proposed smart RFID system would store not only the fixed ID information but also some information which is “active” and encoded in the form of mobile codes indicating the up-to-date situation and associated services' directives...
User mobility management is one of the important components of mobile multimedia systems. In an IP-based mobility case, a mobile node should be able to seamlessly obtain reserved resources after handover to a new access router. This is essential for both service continuity and quality of service assurance. In this paper, we introduce a hybrid architecture which allows a mobile node to seamlessly obtain...
For seamless mobility in networks that use Proxy Mobile IPv6, Proxy Fast Mobile IPv6 (PFMIPv6) is being standardized. The predictive handover mode of PFMIPv6 can minimize packet loss by forwarding user data from the old mobile access gateway (MAG) to the new MAG to which the mobile terminal (MT) makes a handover and by buffering the forwarded data at the new MAG until the MT is attached to the new...
The mean number of handoffs is a fundamental performance measure in any mobile system, as it directly relates to the signaling load in the network as well as to the delivered QoS. As the mobile services are evolving from simple cellular voice calls towards media and data sessions, and as cellular providers are reinventing their businesses by incorporating third party services, the handoff rate will...
We propose in this paper, to replace the two layer 3 Handover mechanisms defined for the situation of macro mobility with IP address change in IEEE 802.16e: ldquoClient-MIP and Proxy-MIPrdquo, by the new protocol created specially for the mobility without services interruptions: ldquoMSCTPrdquo, which has the peculiarity to support several IP sessions at the same time.The purpose of this proposal...
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...
The capabilities of the wireless networks are continuously being enhanced to meet ever growing demand of the higher data rates for accessing wide range of Internet services in the mobile node. The IEEE 802.16e mobile worldwide interoperability for Microwave Access (WiMAX), 3GPP long term evolution (LTE) and 3GPP2 ultra mobile broadband (UMB) wireless technologies are identified as next generation...
Mobile grid combines mobile computing and grid computing and develops rapidly. This paper aimed at designing a general architecture of mobile grid, illustrated mobile grid architecture design principle, presented a novel architecture, analyzed the mobile grid constitutes and logical structure. After that we discussed mobile grid resource and service management and allocation mechanism from description,...
