Abstract |
|
|
| In this paper, a new approach using self-organizing Smart Grid systems is proposed to solve wireless sensor network dynamic channel-assignment. It concerns distribution among Grids whose task is to assign personal station to frequencies with respect to well known constraints. Grids only know their variables and the constraints affecting them, and have to negotiate to find a collective solution. The approach is based on a macro-level management taking the form of a hierarchical group of Grids in the network and handling all RACNs (Regional Radio Access Control Network) in a localized region regardless of the operating band. The approach defines cooperative self-organization as the process leading the collective to the solution: Grids can change the organization by their own decision to improve the state of the system. Our approach has been tested on Shanghai benchmarks of Channel Access Problem. The results obtained are equivalent to those of current existing methods with the benefits that our approach shows more efficiency in terms of flexibility and autonomy. |
