The use of the triple-play services is growing up very quick in the recent years. This has come by the hand of the higher bandwidth offered in broadband access by the service providers. IPTV is the service that has been experienced more request, although it was the least developed. One of its biggest problems is to meet enough quality of experience (QoE) for the customers. This paper presents a QoE management system to guaranty enough IPTV QoE to the customer independently of its type of connection (wired or wireless). The User’s QoE depends, among others, on the video quality, the zapping time and the synchronization time. The system calculates the user’s QoE and notifies him which networks are available for him and have higher QoE. Then, the user decides to roam to that network. The system allows providing ubiquity to multi-network devices.

The increasing demand for services for mobile customers has resulted in the need to develop Web services clients that could be used from mobile devices as well as from PCs, which to date has been the main focus for developers. In this paper we propose an aspect-oriented approach which allows services to be invoked ubiquitously from different type of devices without modifying the structure and encapsulation of the offered service. The paper will show how this can be provided both at compile and at runtime.

Wireless Sensor Networks (WSNs) have a very large growth in research in recent years. They are essentially ad-hoc networks, capable of processing, sensing and transmitting wireless information. These are networks where the specificity of applications becomes something common, due to various types of restrictions (e.g., processing, bandwidth, etc), and energy consumption is the most important restriction. Trying to solve this problem, we present a new approach to saving energy in WSN, based on automatic sensors reconfiguration. Our approach consists of three components: a middleware to handle the heterogeneity of data and applications, an ontology to give a formal semantics to data and a reconfiguration module to communicate with ontology and middleware, and process queries. Some assessments were made in order to show its feasibility, using a case study based on energy consumption. Finally, we argue that its use is feasible and attractive.

Overlay networks are becoming widely used for content delivery and file sharing services because they provide effective and reliable services by creating a virtual topology on top of existing networks. However, the management of overlay networks meet new challenges in the structure, security, services and deployment. This paper presents a survey of the overlay networks and correlated management. The management issues of two typical overlay networks: peer-to-peer and Virtual Private Network are investigated. As a conclusion, the management of overlay networks must import self-management (self-*) and intelligent strategies to deal with the complex management tasks, which are to deal with the dynamic, salability, resilient and security challenges on overlay networks.

This paper presents a novel agent system which provides a user with useful recommendations of behavior and information based on behavior prediction. The agent understands user’s context from a GPS sensor and a mobile phone, and predicts user’s future behavior based on user’s context. And the prediction of user’s future behavior can be used to provide the user with the suggestion of performing behavior and/or the recommendation of information which are relevant to the predicted user’s behavior. Here, behavior prediction is performed by Dynamic Bayesian Network, which can handle time-series data. The experimental results showed that the proposed agent system was enough to provide convenient recommendation services to users.

The number of wireless LAN capable cellular phone models is rapidly increasing. This article studies the possibility to use WLAN capable cellular phone as driving aid in a highway environment. In this scenario the traffic signs are equipped with wireless transmitters to send traffic sign information, which is received and displayed by the WLAN capable mobile devices. Received information acts as a reminder for the current road signs for the driver. This work defines a way to represent and store traffic signs digitally and specifies the form in which the information is transmitted. Capabilities of the proposed system are analyzed and a series of tests on a road environment is presented.

In wireless mesh networks based on IEEE 802.16 WiMAX, each mesh node has its own service area that provides wireless Internet access service to client terminals. The network performance degrades due to radio interference when multiple service areas overlap with each other. To avoid this problem, information of the exact location and size of the service area of neighboring mesh nodes is useful for each mesh node to determine its own service area size. However, the availability of the information depends on the topology construction procedure. In this paper, we discuss a method to determine the size of service areas using the information obtained in topology construction based on IEEE 802.16 WiMAX. Specifically, each mesh node estimates the distance to the nearest neighboring node, and sets the service area size based on this distance. Through performance evaluation, we confirm that our method can increase the size of a single covered area by an average of 32% compared with the existing method, which is the constant service radius, and can reduce the maximum number of overlapped service areas by approximately 50%.

Biological research in agriculture needs a lot of specialized electronic sensors in order to fulfill different goals, like as: climate monitoring, soil and fruit assessment, control of insects and diseases, chemical pollutants, identification and control of weeds, crop tracking, and so on. That research must be supported by consistent biological models able to simulate diverse environmental conditions, in order to predict the right human actions before risky biological damage could be irreversible. In this paper an experimental distributed network based on climatic and biological wireless sensors is described, for providing real measurements in order to validate different biological models used for viticulture applications.

Based on an extensive examining of different industrial and research resources we have recognized that SOA is one of the most progressive IT concepts in the enterprise management. Besides, the rise of social networking in the enterprise, the adoption of Enterprise 2.0, and the use of mobile applications in business are influencing the enterprise SOA development. Thus, in this paper, we focus onto the evaluating the role and place of SOA in new generation of enterprise management paradigm, which highly relies onto the social collaboration tools. Namely, we investigate here integration challenges of main services delivery strategies. Also, we perform an analysis of SOA role in the enterprise social collaboration platform. Next, we define impact factors of social networking and social SOA onto corporate world including placement of a social collaboration layer in new enterprise architecture. And finally, additionally to SOA strategy, we introduce a syndication-oriented architecture concept, defined as a middleware for connecting applications to users, and explore its importance for enterprise collaboration platform.
