Reaserch On The Applications Of Software Agent Ubiquitous Method Based On DFL

The ubiquitous computing has a dramatic development over the last decades,which appears increasingly obious since the"ubiquitous computing"concept put forward in 1990s.The main characteristics of ubiquitous computing are invisible and pervasive.In particular, we focus the discussion on topics related to dynamic and fuzzy characteristics in software Agent and ubiquitous computing based on dynamic fuzzy logic.This thesis is organized as follows.(1) Proposes the the software Agent ubiquitous evaluation model based on dynamic fuzzy logic, then gives the ubiquitous evaluation algorithm.(2) Introduces the software Agent context-aware infrastructure based on dynamic fuzzy logic.In the proccese of software Agent context-aware performance, each Agent constructs a self-model to update it only with context information by itself, and a share-model to update with context information by all other Agents. Trust factor is attributed to each Agent, allowing the increase or decrease of the influence of cooperating to the context informationg credibility. Reinforcement methanism is attributed to each Agent in order to find optimal policy that maximizes the reinforcements.(3) Gives the context task allocation algorithm based on the dynamic fuzzy logic according to the main characteristics of task which is the users need.This paper studys the environment of ubiquitous computing and proposes the software Agent context-aware infrastructure and its application based on dynamic fuzzy logic. There is resource constrain of mobile decices and wireless network, we should propose the inter-domain and intra-domain interactive communication protocol to frequent each software Agent and improve the usage of the resource constrain of mobile decices and wireless network. However, all the work is preliminary and much of them need advanced research. So we pay more attention to them in the future work.
