The absence of any fixed infrastructure and mobility of Mobile Ad-hoc Networks (MANETs) make them attractive for usage in time-critical applications and collaborative computing. Recently MANETs are also used in real-time communications such as audio phone calls. In this paper, we investigate the performance of an outdoor stairs MANET test bed for different scenarios considering throughput and packet loss. We analyze the behavior of Optimized Link State Routing (OLSR) protocol. We design and implement two experimental scenarios: static scenario and moving scenario and draw conclusions regarding mobile communications with different number of hops.

Nowadays Augmented Reality (AR) is an emerging technology that promises significant results in a variety of applications. Despite the great advances in computer graphics and multimedia technologies, there is still a lack in the definition and building of a complete 3D object management system, in order to efficiently store, manage and retrieve such objects. In this paper a novel data model and a building and querying language for 3D objects are presented. This preliminary environment has been properly designed to be sufficiently powerful for including the functionalities and characteristics of modern 3D description languages, such as X3D and Collada, and at same time provides a formalism for optimization aims. Several examples from real Italian Cultural Heritage sites are provided and preliminary results are commented and discussed, showing the main advantages of the proposed system for both creation and information retrieval goals.

File replication in distributed environment has been discussed by many researchers, but the issues like transparency and their impact on the overall system performance, are rarely focused, when deployed in the cloud environment. Distributed computing started with the cluster followed by the grid and is now in the era of cloud computing, where most of the services are accessed, by few clicks. In cloud, services are invoked on demand and there is no need of dedicated resources. It demands the availability of resources(i.e. logical resources), in order to fulfill the user requirements. To make this feasible, on-demand availability of logical resources (LR) is preferred. This work proposes an "OndemandLogical Resource Replication Scheme" (OLRRS) for file replication. OLRRS approach provides migration, access and performance transparency to the system, thereby ensuring the migration decisions about the files. It is also responsible for replicating the file, from one peer server to the other peer server, when the total number of request, on a peer server, for transferring a file reaches the threshold value. The scheme is simulated on JAVA platform and tested on a private cloud. A comparative study of the proposed approach with the Request Reply and Request Reply (RR) Acknowledgement (RRA)protocol is presented, showing the significant reduction by 37.5% to 58%, in terms of total number of messages exchanged for replication.

Recently, there are many problems caused by global environment warming. The limited natural resources require efficient methods and systems for recycling and processing of the wastes for a better environment. One of the problems today is the processing of the kitchen garbage, because when they become in large amounts in small areas, the natural capacity of the environment can not assimilate them. Therefore, construction of the recycling systems is needed to save the resources and minimize the wastes. For this reason, in this paper, we have proposed and implemented waste management robots, which can change the kitchen garbage to compost. Then, the compost can be mixed with the ground and used for growing of vegetables and other plants. The proposed system uses the information network, sensor technology and robot technology. We present in this paper, the implementation of the proposed system and evaluate its performance by experimental results.

The enrichment of Computer Supported Collaborative (CSCL) Systems with emotion awareness features (detect emotion patterns and respond effectively) opens a window to the future of learner-to-computer interaction. In the current paper we present a system's design that attempts to evaluate the learner's affective state while he/she is taking part into collaborative tasks, in three different time-points: (i) before the task, (ii) in real-time (while collaborating) and (iii) retrospective (after the task). For the emotion assessment process, self-reporting and sentiment analysis are explored. Based on effective production rules that correlate emotions or emotion sequences to affective feedback techniques, the system will provide emotion scaffolds corresponding to user needs and feelings.

However today collusion attack such as average attack is appeared. Collusion attack is efficient method for breaking copyright protection scheme of image fingerprint. This paper presented an image fingerprint scheme to resistant collusion attack which is average attack especially. Proposed image fingerprint scheme is applied seam carving technique. Experimental results show that proposed image fingerprint scheme was good performance.

More specific, the paper presents a use case scenario and requirements related to the semantic registration, coordination and retrieval of smart entities. Motivated by these, the paper accentuates the need for, and emphasizes, a framework of Semantic Smart Gateways (SSGF) in the Semantic Web of Things (SWoT), proposing an ontology learning and an ontology alignment method respectively.

The immersive panoramas are widely used to provide virtual tours of real scene. Their use covers a wide field of applications: art, industry, space research, topography, forensic investigation and all those systems requiring the exploration of a virtual environment which simulates a real one. Often sophisticated devices are used to perform the panorama acquisition. In this paper, we present an image based immersive panorama requiring low cost devices for the acquisition task and provides an innovative human-computer interaction approach. Many panoramic images of the same location are captured. The visualization system changes the panorama in a transparent way with respect to the user interaction in function of the position of the virtual point of view. Indeed, the new and more detailed panorama is loaded each time the current point of view position corresponds to a point of acquisition. Our solution is particularly suited to tele-immersive software environments, because it is lighter than a full 3D scene, but the user can lives a full exploration experience of a scene.

In this paper, we propose a system to collect human behavior in detail with higher-level tags such as attitude, accompanying-person, expenditure, tasks and so on. The system makes it possible to construct database to model higher-level human behaviors that are utilized in context-aware services. The system has two input methods, i.e., on-the-fly by a smart phone and post-processing by a PC browser. On the PC, users can interactively know where and when they were, which results in easily and accurately constructing human behavior database. To decrease numbers of operations, users' repetitions and similarity of among users are used. According to experiment results, the system successfully decreases operation time, higher-level tags are properly collected and behavior tendencies of the users are clearly captured.

Photonic crystal or electromagnetic band gap structure are expected to play important roles in optical signal processing and optical fiber communications, because of its unique and sensitive characteristics for wavelength based on photonic band gap theory. In such signal transmission and processing, high density multiplexing in wavelength domain is expected due to its sensitiveness with respect to optical wavelength. This is important to improve capacity of information transmission in the future photonic network. In this paper, experiments based on X-shaped branching wave guide reported by using scale models in microwave frequency. Comparisons of the parameters which could be indicated as Q factor and extinction ratio were summarized. Filtering characteristics of each structure were measured to be certified that X-shaped wave guide can be operated as filter components with good separation in wavelength division multiplexing (WDM) systems.
