Inhoud: The extension of the ATM infrastructure with wireless access and mobility offer a great service advantages and high traffic performances. Allowing the Wireless ATM network in order to maintain the already QoS of ATM networks, some protocols of wireline architecture should be updated. The adaptation of the existing protocols to wireless requires integrating radio access functionalities and terminal mobility management. This last is an important factor in provisioning multimedia applications over wireless link. It adds the advantages of guarantying resource availability to the mobile terminals with QoS requirements. Mobility management needs several tasks as paging, location updating, routing, and handover. Particularly, handover has an important role to improve the services of WATM system. It is one of the major tasks that are used to support continuous transmission for a mobile terminal into different radio coverage areas. This research focuses on presenting an optimized handover algorithm. We propose a flexible architecture for implementing handover procedure based on intelligent decision strategy. This architecture is able to actively deploy different handover type. It can manage different network situations and allow mobile terminal to be connected to the most suitable base station.
