Abstract:
In recent years, many research trends have been arisen in the current state-of-the-art in Wireless Sensor Networks (WSNs). One of new research trends is to design a Wi-Fi sensor device that provide better data exchange rate. In this paper we introduce new Wifi mote platform that is capable of large data exchange and fulfills the requirement of the low cost which is ported the core of Contiki Operating System inside; the simulation�s solution is also provided to measure the power consumption for this mote in advance.Wi-Fi mote platform is a new researching in WSNs which name is UITmote with many advantages as: using Wi-Fi IEEE 802.11 technology to transfer data with high data rate, low-cost hardware and using Contiki operating system to optimize and manage the power consumption efficiency. UITmode proved extremely effective for WSNs whenever large data-rate exchange is required (anti-thief system, record the habits of the wild animals or supervision of construction works). Besides that, simulation UITmode in Cooja can demonstrate the efficiencies of it and also predict the context can be happened in real life to design the WNSs when use it by simulation.

Keywords: wireless sensor network, low power consumption, Contiki OS, UITmote.
