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...
JamLab: augmenting sensornet testbeds with realistic and controlled interferenc...
Boano, Carlo Alberto; Voigt, Thiemo; Noda, Claro; Römer, Kay; Zúñiga, MarcoRadio interference drastically affects the performance of sensor-net communications, leading to packet loss and reduced energy-efficiency. As an increasing number of wireless devices operates on the same ISM frequencies, there is a strong need for understanding and debugging the performance of existing sensornet protocols under interference. Doing so requires a low-cost flexible testbed infrastructure that allo...

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.
