Appeared in 2nd ACM International Workshop on Wireless Sensor Networks and Applications (WSNA) 2003 MANTIS: System Support for M ultimod A l N e T works of I n-situ S ensors H. Abrach, S. Bhatti, J. Carlson, H. Dai, J. Rose, A. Sheth, B. Shucker, J. Deng, R. Han University of Colorado at Boulder Department of Computer Science Contact author: [email protected] ABSTRACT The MANTIS M ultimod A l system for N e T works of In-situ wireless S ensors provides a new multithreaded embedded operating system integrated with a general-purpose single-board hardware platform to enable flexible and rapid prototyping of wireless sensor networks. The key design goals of MANTIS are ease of use, i.e. a small learning curve that encourages novice programmers to rapidly prototype novel sensor networking applications in software and hardware, as well as flexibility, so that expert researchers can leverage or develop advanced software features and hardware extensions to suit the needs of advanced research in wireless sensor networks. Categories and Subject Descriptors D.4.7 [ Operating Systems ]: Organization and Design - real-time systems and embedded systems, interactive systems . C.3 [ Computer Systems Organization ] Special-purpose and Application-based Systems - real-time and embedded systems . General Terms Design, Experimentation, Performance, Security, Human Factors. Keywords Wireless sensor networks, operating systems, lightweight, multimodal prototyping, dynamic reprogramming, GPS. 1. INTRODUCTION The growing popularity of wireless sensor networks (WSNs) has placed increasing demands upon the infrastructure of today's general-purpose hardware/software sensor systems [1,2,3,4] to support improved flexibility, ease of use, and lower cost. The MANTIS MultimodAl system for NeTworks of In-situ wireless Sensors provides a new multithreaded embedded operating system integrated with a general-purpose single-board hardware platform to enable flexible and rapid prototyping of wireless sensor networks. The key design goals of MANTIS are ease of use, i.e. a small learning curve that encourages novice programmers to rapidly prototype novel sensor networking applications, as well as flexibility, so that expert researchers can continue to adapt and extend the hardware/software system to suit the needs of advanced research. The first goal in the design of the MANTIS OS (MOS) was to meet the objective of ease of use or convenience while also adapting MOS to the resource constraints of wireless sensor networks, namely limited memory and power. To lower the barrier to entry into the field of sensor networks and encourage novice application developers, early design choices of MOS adhered to familiar themes in programming languages and operating systems design. For these reasons, MOS selected as its model the classical structure of layered multithreaded operating systems, which includes multithreading, pre-emptive scheduling with time slicing, I/O synchronization via mutual exclusion, a standard network stack, and device drivers. Familiarity with these
