The service concept is frequently used as an abstraction of software and hardware resources. Service oriented architectures should offer mechanisms of service discovery, advertisement and location. So, it represents a key problem in very dynamic networks like ad hoc networks. Various researches treating the communication in these networks carried an unquestionable interest to use virtual dynamic topologies to get a better network organization. In this paper, we give a classification and discuss the different virtual topologies in ad hoc networks and their advantages in implementing service oriented applications.
