Smart-HOP: a reliable handoff mechanism for mobile wireless sensor networks
Fotouhi, Hossein; Zúñiga, Marco; Alves, Mário; Koubâa, Anis; Marrón, PedroHandoff processes, the events where mobile nodes select the best access point available to transfer data, have been well studied in cellular and WiFi networks. However, wireless sensor networks (WSN) pose a new set of challenges due to their simple low-power radio transceivers and constrained resources. This paper proposes smart-HOP, a handoff mechanism tailored for mobile WSN applications. This work provides t...

Fotouhi, Hossein; Alves, Mário; Koubâa, Anis; Zúñiga, MarcoThis poster abstract presents smart-HOP, a reliable handoff mechanism for mobility support in Wireless Sensor Networks (WSNs). This technique relies on a fuzzy logic approach applied at two levels: the link quality estimation level and the access point selection level. We present the conceptual design of smart-HOP and then we discuss implementation requirements and challenges.

Fotouhi, Hossein; Alves, Mário; Koubâa, Anis; Baccour, NouhaWireless sensor network (WSN) applications such as patients’ health monitoring in hospitals, location-aware ambient intelligence, industrial monitoring /maintenance or homeland security require the support of mobile nodes or node groups. In many of these applications, the lack of network connectivity is not admissible or should at least be time bounded, i.e. mobile nodes cannot be disconnected from the rest of ...
Demo abstract: RadiaLE: a framework for benchmarking link quality estimators
Baccour, Nouha; Jamâa, Maissa Ben; Rosário, Denis do; Koubâa, Anis; Alves, Mário; Becker, Leandro B.; Youssef, Habib; Fotouhi, HosseinLink quality estimation is a fundamental building block for the design of several different mechanisms and protocols in wireless sensor networks (WSN). A thorough experimental evaluation of link quality estimators (LQEs) is thus mandatory. Several WSN experimental testbeds have been designed ([1–4]) but only [3] and [2] targeted link quality measurements. However, these were exploited for analyzing low-power li...
