Radio Frequency IDentification (RFID) is a rapidly developing wireless technology with key features which anticipate its outstanding position in the upcoming era of pervasive computing. Even though object identification is its primary objective, it is generally accepted that RFID systems can revolutionize various commercial applications. Despite its(More)
Location awareness of a user or a device has always been considered as a key element for enhancing network performance and improving user experience by enabling efficient mobility and innovative location-based services. In this paper, we present our proposal named WIFE (Wireless Indoor positioning based on Fingerprint Evaluation), a user-based location(More)
Indoor positioning has gained more and more interest lately since it offers the possibility of using the location information in several network functionalities improvement or user services deployment. In this paper, we consider the case of WLAN-based indoor positioning for its simplicity and ease of deployment. With our focus on scene analysis methods, we(More)
Handoff management is one of the main research challenges for the realization of the envisioned mobile and wireless Internet. This is mainly due to the latency delay and energy consumption introduced during handoff, which are of major concern for real-time applications and battery-constrained mobile terminals. In this paper, we explore whether handoff(More)
Handoff management is the main research challenge encountered for providing mobility support over the wireless Internet. Actually, during the migration of a mobile node (MN) among different network domains, its IP traffic is interrupted due to the latency delay introduced by the handoff process. The main source of such latency is attributed to the(More)
Indoor positioning techniques based on radio fingerprints outstand over other localization methods because of their independence from radio propagation models and cost-effectiveness in terms of hardware and deployment requirements. However, their reported best achieved accuracy is bounded due to the random environmental changes which cause the inconsistency(More)
