CBay : Extending auction algorithm for component placement in the Internet of machines

Abstract

International audienceThe Internet of machines is a system composed of interconnected nodes that inter-operate to run applications. Such applications can be implemented by the encapsulation and the cooperation of several software entities called components. These components are distributed on nodes with various resources (memory, computation capacity, bandwidth, battery charge, etc). Placing components on nodes is a crucial step for both the application and the target machines. The choice of placement actually influences their performance. Hence, the deployment has to take into account the needs and the functional/non functional properties along with the system's available resources and its overall performance. Many algorithms have been proposed, including one based on a principle of auction: DecAp, which allows components' dynamic redeployment to better meet the system's evolution. We present in this article an extension of DecAp by adding the management of available resources (memory, bandwidth and computing capacity) to the redeployment strategy
