Inter-Cell Interference Coordination (ICIC) techniques are proposed as solutions to alleviate the negative impact of interference on system performance, while enhancing the provided Quality of Service (QoS). Typically, the available bandwidth is divided into inner and edge sub-bands. Users are also classified into interior and edge users. The available resources in each zone are exclusively allocated...
In this work, we propose an auction-based resource negotiation for flexible video traffic offloading over heterogeneous wireless networks. The goal of the proposed system is to alleviate long term evolution (LTE) traffic congestion by offloading video traffic through WiFi network in a flexible scale while providing stable video streaming services to users with the minimum monetary cost. The fountain...
Resource allocation is an important topic with a wide range of applications. In many practical cases, users and resource suppliers are players in the market. As a result, much effort has been made in applying market mechanisms (such as auction and game-theoretic results) to resource allocation. The conventional approach in such studies is to consider cases where users' resource demands are fixed....
When sharing the unlicensed band with Wi-Fi users in unliened LTE (U-LTE) systems, the most critical issue is how to guarantee the harmonious coexistence between the two systems. On the other hand, when sharing the licensed band with the micro base station (MBS) in the small cell base station (SBSs), the co-channel interference needs to be properly coordinated. To address these two issues, power control,...
This paper presents an approach for solving the resource allocation problem in heterogeneous networks (HETnets). An optimization model is formulated; its main objective is to achieve the best Quality of Service (QoS) measured by the Carrier to Interference Noise Ratio (CINR). This model is a quadratically constrained optimization problem with continuous and boolean variables. It is solved by an approximation...
In this paper, we study an emerging type of wireless network - Hybrid Wireless Networks (HWNs). A HWN consists of an infrastructure wireless network (e.g., a cellular network) and several ad hoc nodes (such as a Mobile ad hoc network). Forming a HWN is a very cost-effective way to improve wireless coverage and the available bandwidth to users. Specifically, in this work we investigate the issue of...
Mobile users want to be connected to a network at any time for mobile computing applications, such as thin-client communications and network games, even while they are moving toward their destinations. They could take an alternate route (called a “longcut” route) if the route is geographically longer than a shortcut route to their destinations but gives more wireless network resources, such as bandwidth...
The following topics are dealt with: parallel processing; distributed processing; operating systems; middleware; scheduling; load balancing; computer networks; multiprocessing systems; mobile computing; pervasive computing; software development; Web services; wireless networks; data security; and cloud computing.
In this paper, a resource management approach based on IEEE1900.4 architecture for heterogeneous wireless network is given. The rest of the paper is organized as follows. In Section II, the radio resource management approach consisting inter-network resource allocation, RAN resource reservation and access network selection in heterogeneous network is present.
In wireless ad-hoc networks, there are several characteristics different with wired networks. The differences are changing of network topology, limited resources like bandwidth and energy and so on. In these days as the energy issue becomes more important, it is required to research about the efficient resource allocation methods optimized in wireless networks. In the paper, we improve LAR (Location-Aided...
There is a problem of unfairness in allocation of radio resources among heterogeneous mobile terminals in heterogeneous wireless networks. Low-capability mobile terminals (such as single-mode terminals) suffer high call blocking probability whereas high-capability mobile terminals (such as quad-mode terminals) experience very low call blocking probability, in the same heterogeneous wireless network...
Service delivery in a heterogeneous wireless network environment requires the selection of an optimal access network. Indeed, the selection of a non-optimal network can result in undesirable effects such as higher costs in terms of new call blocking and handoff call dropping rates or poor service experience. Network selection in such an environment is influenced by several factors related to network...
This paper proposes a predictive controller based on adaptive resource management techniques for multi-service wireless cellular networks to keep the handoff failure rate (HFR) below a target value regardless of the traffic dynamics and bandwidth requirements of the service types. In this paper, we propose a neural nod feedback algorithm to control the reserved resource. Simulations results indicate...
Mobile appliances are getting used in many areas. The explosive growth of the mobile appliance markets and requests of a lot of demands in mobile-related services lead many researches to apply for wired network environment services to mobile appliances. However, there are too many restrictions like connection failures to apply service that requires large scales of multimedia data, or services that...
The increasing use of wireless networks and the popularity of multimedia applications, leads to the need of QoS (quality of service) support in a mobile IP-based environment. This paper considers the reservation of resources in the micromobility scenario. The reasons for path changes in the access network are investigated. Based upon this, we present the functionality that should be present in the...
