Mote is a low-cost battery-powered sensor network node that integrates the multiple sensors, onboard processing and wireless communication [1]. This paper proposes the architecture for a new generation mote that is needed in wireless sensor & actuator networks (WSAN), with emphasis on semantically meaningful flexibility in operation. The first version of the mote coming out around May 07 would be fabricated by integrating off-the-shelf commercial components into a mote in order to test the functionality of the mote & the SW. The second version expected around Dec 07, would be built around FPGA and RF transceiver chip. The functionality of the mote presented in this paper is derived from the concept and the features of Mote presented in the paper on DOMA by the authors [19]. Specifically it exhibits the capability of exploiting multiple protocols for communication, the capability to use semantic web, capability to self organize in the “ad-hoc” network environment, process considerable information in the mote itself based on the semantic needs, use specially designed real time operating system to suit the requirements of size and functionality, and much longer life time of the battery power. In order to meet the above processing requirements, the motes under development have, more processing power and address larger memory than the currently available motes and support the use of general-purpose sensors instead of the custom built sensors.
