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 off-the-shelf components. UTMOST offers a number of improved functionalities over previously designed platforms, e.g., energy consumption, wireless reprogramming, processing frequency, and 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.
