Mica2 sensors run the TinyOS [Levis:04] operating system. TinyOS is an open-source operating system especially designed for wireless sensor networks. It is a component-based operating system, hence programmers can integrate only the needed components to keep the code size small. Thus it is suitable for resource-constrained sensor networks. TinyOS models an event-driven execution, and includes power management and flexible scheduling to support unpredictable wireless communications and physical world interfaces. The component library includes “network protocols, distributed services, sensor drivers, and data acquisition tools”. The components and the modules can be used as it is or can be modified to fit into the custom applications requirements. [details]

SOS is designed for "mote-class wireless sensor networks". SOS kernel implements "messaging, dynamic memory, module loading and unloading, and other services". SOS uses a dynamic model that allows program changes on the fly and supports concurrent applications. SOS allows dynamic loading of software modules to create a system "supporting dynamic addition, modification, and removal of network services".</a></p> <p><a href='http://nesl.ee.ucla.edu/projects/SOS/'>DETAILS about SOS</a></p> <ul> <li> <a href='http://www.cs.ucla.edu/~kohler/pubs/han05dynamic.pdf'>A paper discussing the design of SOS and comparison between TinyOS and SOS</a> </li></ul> From: http://sitestree.com/?p=5145<br /> Categories:111<br />Tags:<br /> Post Data:2010-05-12 12:28:59<br />
