A hybrid offloading network system for offloading computational tasks, comprises a server cloud that is adapted, when receiving an offloading task, to execute the offloading task; an ambient cloud comprising a plurality of smart devices, wherein each smart device is adapted to deliver, as an offloader, its offloading task and attributes of the offloading task, and/or is adapted, when receiving an offloading task, to execute, as an offloadee, the offloading task. A smart router manages information on currently available computational resources both in the server cloud and the ambient cloud. The smart router receives offloading tasks from the ambient cloud, decides which candidate among the server cloud and the offloadee(s) of the ambient cloud, each received offloading task is to be forwarded to, based on the resource information of each candidate, the attributes of the offloading task and/or network bandwidth, and forwards the offloading task to the decided candidate.
