Abstract

In this paper we present a new approach to test the conformance of a wireless ad hoc routing protocol. This approach is based on a formal specification of the DSR protocol described by using the SDL language. Test scenarios are automatically generated by a tool developed in our laboratory. A method enabling to execute them on an implementation into a real network is illustrated. Indeed, an important issue is to execute some generated test scenarios on a dynamic network in which the links are routinely modified. Therefore, the concept of selfsimilarity is presented to reduce the number of nodes by collapsing them in a real network. This enables to execute the test scenarios in defining a relationship between the network and specification topologies.
