Contract-less wireless plans, in which customers are not locked into terms with providers, are becoming prevalent. The next step in this evolution is a contract-less competitive mobile wireless market in which a customer can, quite fluidly and seamlessly, choose to switch amongst wireless providers based on competitive terms at almost any time or place. This paper explores the concept and design of...
The fourth generation of mobile wireless networks (4G) is expected to be the most promising architecture for QoS provision due to its scalability, convenience for mobility support and capability of interworking heterogeneous radio access networks which ensure both session continuity and QoS support. One major design issue of the 4G is the support of optimized handoff functionalities. More specifically,...
One of the vision of next generation networks is an all-IP network supporting heterogeneous access technologies for the purpose of providing the mobile user with roaming capability across different networks. To enable this type of mobility known as vertical handover (VHO), an intelligent technique is needed in order to perform the service continuity. This paper presents a multi-agent based approach...
The scenario that different RATs are used to satisfy mobile user's two or more application requirements simultaneously in heterogeneous network is called multi-service environment. Recently, powerful multi-mode wireless terminal, which is suitable for multi-service situation, has become the test product. The mobility management (MM) issues, especially handover, of different interfaces in the test...
In Wireless Access in Vehicular Environment (WAVE), the WAVE Short Messages (WSMs) are broadcasted from the Roadside Unit (RSU) to the Onboard Units (OBUs). On the other hand, WAVE does not specify how to provide WSM-based unicast service to an OBU. In this paper, we devise location tracking procedure so that an OBU can be tracked and receive unicast messages. We also investigate the effect of vehicle...
This paper proposes a general architecture for the Next Mobile Network (NMN). NMN is composed of four planes: Advanced Mobile Access (AMA), Optical Mobile Network (OMN), Virtual Mobile Network (VMN), and Service Delivery Network (SDN). AMA, OMN, and VMN are revolutionary additions while SDN is an enhancement of that found in the All-IP network as SDP (Service Delivery Platform). NMN aims at offering...
With the penetration of broadband wireless access network and devices, interactive multimedia streaming to handhelds has become a reality. However, it is still challenging to offer such services to a large number of users in a cost-effective manner. With the increase of battery lifetime, memory capacity and processing capability, and the fact that many mobile devices nowadays are equipped with multiple...
Enhancements of transmission speed and mobile node capability in wireless access networks enable people to watch movies and share large files with friends via their personal mobile devices. Considering the increased demand for such services in the next five to ten years, we will need to introduce P2P architectures to mobile networks to handle the large number of requests from mobile nodes. However,...
3GPP has standardized the use of forward error correction for the provision of reliable data transmission in the mobile multicast framework. In this paper we present a study of the impact of application layer forward error correction on power control during mobile multicast transmission. The evaluation is performed with the aid of a novel scheme that allows the simulation of FEC impact on both streaming...
Roaming across different access technologies permit people to access Internet via heterogeneous wireless networks such as WLAN, WiMAX, GPRS, 3G and Beyond 3G networks. The convergence of heterogeneous wireless access networks with handoff support enable mobile nodes to freely move in and out of any available networks without breaking the connection to the Internet. In this paper, an Adaptive Cross...
Current 3GPP Release-8 is addressing Evolved-UTRAN or LTE as a new access network and SAE / EPC as an improved version of 3,5G core based on All-IP infrastructure. This paper describes the objectives of the actual LTE / SAE standard related to its deployment in Bosnia and Herzegovina and suggests how to implement it smoothly in a mid-size network.
Mobile position-aware systems combined with modern wireless technologies are getting more and more important and everyone seems to realize that the market is a high potential industry. For mobile network it is a way to differentiate many mobile applications and services from PC (Personal Computer) applications and wired Internet services. Using mobile devices, LBSs (Location-Based Service) leverage...
In the Internet, nodes are identified using IP addresses that depend on their topological location. IPv4/IPv6 translation technology involves address mapping between IPv6 and IPv4 nodes and the methods used to translate protocols, where nodes are in their respective IP version of network. The various IPv4 addressing mechanisms and addressing architectures are studied. The detailed study reveals that...
This paper proposes a radio resource management framework for integrated network selection mechanism control in multi- network environment as an interaction between the service providers and users in competitive manner to admit high priority users or the services that maximize their rewards. The proposed scheme comprises of three steps namely as user profile, service profile and access network selection...
Many military research efforts have concentrated on how to allow war-fighters to take advantage of all available information within the battlefield in a rapid and flexible manner. As a result, the development of the Global Information Grid (GIG) was the key enabler for this process; hence, adding to the development of the mobile networking part of the GIG, the concept of the Mobile Ad hoc Network...
GPRS offers the user can always on connection to Internet and Intranet. Some of the services may require high level of security. This can be financial transaction over the Internet, or exchange of confidential documents from a company's Intranet to an employee. It is important to have strong focus on the security, so companies and persons that demand high level of security can take advantage of the...
The overall goal of the EARTH project is to identify concepts that will further improve the energy efficiency of wireless access networks. This paper elaborates on radio node level issues addressed by the project. The focus is on radio base station components and radio link concepts to adopt the potential for energy efficiency offered by holistic joint optimisations. A new class of power efficient...
In the future, most mobile nodes will have multiple radio interfaces, and this feature can be exploited to reduce the transmission cost in wireless data access applications. In this work, we propose cooperative wireless data access algorithms with strong consistency in multi-radio wireless networks. It can be shown that cooperation with neighbor nodes can reduce the expensive transmission cost over...
There are several radio access technologies providing connectivity for mobile devices. In the future, more and more mobile devices will be capable of supporting more than one access technology. For being able to use these technologies simultaneously, there is a need for multihoming capabilities. Due to the variety of access technologies and the ability to use them simultaneously, new concepts for...
Given limited network resources, applications, particularly those that support real-time services, must deliver an ambient quality-guaranteed service. Different applications are associated with different Quality of Service (QoS) concerns, as well as different QoS control parameters. This work discusses the QoS specifications of three wireless access technologies, 3G, WiMAX and WiFi, in the design...
