Distributed processing using resources of intelligent lighting elements of a lighting system
An exemplary lighting system utilizes intelligent system elements, such as lighting devices, user interfaces for lighting control or the like and possibly sensors, and utilizes network communication amongst such intelligent system elements. Some processing functions performed within the system are implemented on a distributed processing basis, by two or more of the intelligent elements of the lighting system. Distributed processing, for example, may enable use of available processor and/or memory resources of a number of intelligent system elements to process a particular job. Another distributed processing approach might entail programming to configure two or more of the intelligent system elements to implement multiple instances of a server functionality with respect to client functionalities implemented on intelligent system elements.

implementing, in at least two of a group of intelligent system elements forming a lighting system, a server function with respect to an overall processing function of the lighting system and related server communications via a data communication network;
operating the server function in at least two server intelligent system elements in a distributed processing fashion, at least two server intelligent system elements each including a respective server instance by:
obtaining a processing job to be performed on a distributed processing basis using resources of the group of intelligent system elements;
querying, via the respective server instance, a respective sub-group of intelligent system elements and receiving responses from the respective sub-group of intelligent system elements as to whether or not the respective sub-group of intelligent system elements have processing or memory resources available for the processing job,
based on the responses, via the respective server instance, allocating portions of the processing job to the respective sub-group of intelligent system elements,
sending, via the respective server instance, data and instructions to the respective sub-group of intelligent system elements, for performing an allocated portion of the processing job, and
receiving, via the respective server instance, from the respective sub-group of intelligent system elements results of the performance of the allocated portions of the processing job;
processing the received results to determine an overall result of the processing job, and

9. The method of claim 1 , further comprising:
analyzing, via the respective server instance, the responses and/or aspects of the received results, to determine distributed processing metrics of performance of the respective sub-group of intelligent system elements, with respect to handling of the processing job;
