UTD Mote System ( UTMOST ) : Improving Functionalities in Wireless Sensor Nodes

The UTD mote system (UTMOST) is a low power all purpose platform for wireless sensor nodes (WSN) based on offthe-shelf components. UTMOST offers a number of improved functionalities over previously designed platforms, e.g., energy consumption, wireless reprogramming, processing frequency, an d storage capability. This paper details how hardware components are selected and integrated to enable such improvements. Experimental measurements demonstrate, among other things, a reduction of 37% in sleep current compared to previous platforms. The proposed design enables extended remote programming and lower maintenance, longer lifetime, and the support of more computational intensive applications.
