An effective cooperation mechanism among multi-devices in ubiquitous network

The aim of MANET is to supply ubiquitous services through communications among a set of devices deployed in ubiquitous stub environment. Due to the dynamic characteristics of MANET and the limit of devices' capacity, it is a critical challenge to select an optimal set of device to supply high quality service constantly. In this paper, the Multi-Devices Cooperation problem is imported with ubiquitous service model and network model. And a dynamic multi-devices cooperation approach is proposed to support three processes of service requiring, multi-devices cooperation selecting and quality maintenance. At last, the simulation is implemented with OPNET and MATLAB and the result shows this approach is better applied to support ubiquitous services.
