Integrating sensor measurements through CM cards as an OMF service

Several OMF-based testbeds are using Chassis Manager (CM) cards for autonomously controlling and monitoring the status of nodes. CM cards are typically microcontroller boards and can be connected to different kinds of modules, including sensor modules. The NITOS testbed, which has recently adopted the use of CM cards, features various types of sensors connected to them. Measurements can be easily obtained through dedicated web services running on the microcontroller, through a network interface. This demo describes the implementation of an OMF service on top of these CM card measurement web services. This service can either be requested directly by an experimenter who wishes to obtain a specific sensor measurement, or it can be utilized in OMF experiment scripts. © 2012 ICST Institute for Computer Science, Social Informatics and Telecommunications Engineering
