Abstract:
1. A microcontroller based system for resource constrained environments comprising: a microcontroller used to control a wireless sensor node in a wireless sensor network comprising memory storing program code, wherein execution of said program code by said microcontroller implements a real-time operating system (RTOS) comprising: wherein a single call-return stack is utilized by said scheduler common to said tasks and wherein the task resume addresses of said tasks are maintained on said single call-return stack such that said tasks are resumed in the reverse order in which they are suspended; wherein said wireless sensor node is configured to collect measurements of a plurality of parameters, to log said measurements and to trigger an alarm if said parameters are outside predetermined thresholds; and wherein said wireless sensor node is configured to communicate with a host gateway coupled to a wired network, so that said measurements are available in real-time through a local or wide-area network and wherein communication to said host is secure requiring authorization.
