Service-oriented Multi-devices Dynamic Cooperation Mechanism

It is hard to supply high quality service constantly because of the dynamic characteristics of MANET and the limit of devices capacity in ubiquitous environment. In this paper, personal ubiquitous service model is defined and Multi-Devices Cooperation Problem (MDCP) is imported based on service context. And personal multi-devices cooperation mechanism is proposed to support three processes of service requiring, multi-devices cooperation building and quality monitoring. Finally, the simulation is implemented with OPNET and MATLAB. The result shows this mechanism could support personalized services, improve 3%～17% about packet loss rate, save 0%～20% in energy consumption and cut short in the time of service re-start than Dynamic Task-embedding Anycasting (DTA) and Service-oriented Device Anycasting (SDA).
