The complexity (in terms of services and multimedia streaming) and dynamicity of telecommunication networks are continually growing, making network management and control more and more difficult. Such a management must be adaptive, dynamic and smart. In order to be sure of getting the best management mechanisms’ choice, a monitoring operation becomes fundamental. This paper presents a new adaptive monitoring approach based on a multi-agent system, taking into consideration the features of the networks namely flexibility, dynamicity, heterogeneity of users generated traffic, etc. A two-layers monitoring architecture is proposed in this paper. The first layer is responsible for dealing with monitoring of some local parameters, which are useful for the second layer. Indeed, this latter is adaptive, autonomous and able to make new decisions- about the data to monitor and the management mechanisms to activate- based on the current node’s state.
