A Novel Colored Time Petri Net Model For Policy Management And Context Awareness Procedure In Manet

Because the phases of policy management in Mobile ad hoc network (MANET) and the procedure of context awareness in cognitive wireless network are very unclear and complicated. We aim to provide a useful description way to analyze the mechanism of policy-based network management (PBNM) in MANET, the structure of cross-layer components of a context-aware distributed PBM system and the context awareness procedure distinctly. In this paper, we propose a novel Colored Time Petri Net (CTPN) Model to describe the procedure of policy management and context awareness. According to the definition of CTPN and the self-management policies of MANET, the procedure of policy management is divided into 3 phases, and a corresponding CTPN model is designed. Based on the 4 phases of distributed context-aware model, a whole CTPN model of context awareness procedure is presented. And a simplified support graph of context awareness procedure is proposed in order to illustrate the effectiveness of the method.
