In this paper an efficient fuzzy logic based solution for the specification and performance evaluation depending on generation of fuzzy rules is presented. A new property matching mechanism is defined; in general, a requirement with attributes is chandelled in the following manner: the basic functionality is ensured, matching properties names according to the classical reading/writing strategy. Usually several solutions result from this first step. Second, the preliminary solutions are selected and hierarchies according to the degree of attribute matching. This is done by fuzzy logic. . I will describe the basic principles of the proposed solutions and illustrate them for implementing atomic read write shared memory in mobile ad hoc network.
