Broadband Forum's CPE Wan Management Protocol (CWMP/TR-069) became, in the last few years, a key industry standard for the management of devices that, despite located in the local network of domestic broadband users, still need to be directly managed by operators due to their relevance to added value services such as VoIP, IPTV, VoD or femtocell(More)
This paper presents a novel approach to the design of globally asymptotically stable (GAS) position and velocity filters for Autonomous Underwater Vehicles (AUVs) based directly on the sensor readings of an Ultra-short Baseline (USBL) acoustic array system and a Doppler Velocity Log (DVL). The proposed methodology is based on an equivalent linear(More)
A new sensor based homing integrated guidance and control law is presented to drive an underactuated autonomous underwater vehicle (AUV) towards a fixed target, in 3D, using the information provided by an ultra-short base line (USBL) positioning system. The guidance and control law is firstly derived for the vehicle's kinematics expressed as the time(More)
In typical video-to-video transmissions, security and confidentiality is becoming an issue of greater importance, but these features come at a cost. In mobile environments, where CPU time is a valuable resource, such features should be thoroughly thought over as they usually require heavy computational resources. In this paper a short analysis on existing(More)
This paper addresses the problem of decentralized state estimation in formations of Autonomous Underwater Vehicles (AUVs) with fixed topologies. In the envisioned scenario, each AUV in the formation estimates its own state relying only on locally available measurements and data communicated by neighboring agents, requiring lower computational and(More)
