Wireless Ad hoc networks provide a flexible and adaptable infrastructure to transport data over a great variety of environments.\nRecently, real-time audio and video data transmission has been increased due to the appearance of many multimedia applications.\nOne of themajor challenges is to ensure the quality ofmultimedia streamswhen they have passed through a wireless ad hoc network.\nIt requires adapting the network architecture to the multimedia QoS requirements. In this paper we propose a new architecture\nto organize and manage cluster-based ad hoc networks in order to provide multimedia streams. Proposed architecture adapts the\nnetwork wireless topology in order to improve the quality of audio and video transmissions. In order to achieve this goal, the\narchitecture uses some information such as each node�s capacity and the QoS parameters (bandwidth, delay, jitter, and packet loss).\nThe architecture splits the network into clusters which are specialized in specific multimedia traffic. The real system performance\nstudy provided at the end of the paper will demonstrate the feasibility of the proposal.
