Wireless sensor networks are widely deployed and implicitly characterized by stringent energy and computation constraints. Sensor nodes are vulnerable to false positive and false negative attacks that inject false data through compromised nodes. Such attacks cause false alarms with energy drain and information loss. Although several en-route filtering schemes have been designed to detect the attacks,...
The number of applications available since the late 2010's, and the number of smartphone user sharply increasing. However, not all applications are not useful or helpful. In other words, to obtain satisfactory results in the search can be difficult means. Users to find what they want to search for a many times. To solve this problem, previous studies have proposed the use of recommender systems. Most...
Nowadays health concerns are effectively becoming ubiquitous. Most people have the need to effectively control their nutritional consumptions, mostly due to health issues. Personal computational devices may assist this control with a solution that allows an efficient management of each individual nutritional profile.
Recent rapid advancement in both pervasive mobile computing and cloud service has been driving numerous new applications in the ubiquitous media consumption. To provide mobile user with richer experiences, it is desired for the service providers to offer highly relevant recommendations of media content to the users by exploring user-user, user-media and user-context relationships. Furthermore, contemporary...
This paper introduces a hybrid recommendation platform providing information about tourist resources depending on the user profile, location, schedule and the amount of time for visiting interest points isolated or combined in a route.
With the emergence of pervasive environment, mobile recommender needs to make use of user in-time contextual information to provide personalized recommendation. In this paper, a proactive context-aware news recommender in mobile hybrid P2P network is designed and implemented. We develop a general Analytic Hierarchy Process (AHP) model through empirical studies. We discuss how the relative weight of...
Collaborative filtering technology is the key technology of recommendation system. However, collaborative filtering technology has been suffering from sparsity that it needs mass ratings from users to improve precision. In traditional e-commerce, asking users to rate on their own initiative will degrade experience of users, let alone the mobile business environment. So, both in e-commerce and m-commerce,...
Ubiquitous computing has gained momentum over the last years with the expansion of mobile devices. One area of pervasive computing is context-aware systems which are applications designed to react to the constant changes in the environment. This project presents a context aware platform that handles context acquiring and processing and manages the service provisioning. The platform alleviates the...

Interval training is a well known exercise protocol which helps strengthen and improve one's cardiovascular fitness. It interleaves high intensity exercises with rest periods. Despite the known benefits, proper scheduling and completion of interval training routines are not easy to perform. For example, without expensive equipment such as a treadmill, there is almost no way to figure out one's speed...
Mobile navigation service is one of the most important location based services. With the rapid advances in enabling technologies for ubiquitous computing, more and more active or passive devices/sensors are augmented in the indoor environment, indoor environment has become smarter. This paper proposes that by introducing the notions of smart environment and ambient intelligent, a ubiquitous indoor...
Mobile and ubiquitous computing have increased the need for mobile users to expect accessing preferred services, whenever they want and wherever they are. Users do not have to explicitly specify and configure their working environment each time they move from one location to another. The necessary adaptation to cope with the changing environment should be initiated by services rather than by users...
