After description of the deployment of forces on a theatre of operation, the paper addresses the organisation of the sub-networks in such a deployment, and the generic network architecture required for bring together the different network capabilities. The paper shows how dynamic control of the architecture can provide an efficient solution for Service Delivery, through a description of three services for ad hoc systems able to adapt rapidly to mobile environments Messaging and Mobile Multimedia Services. The architecture describes the technical solutions for Localisation of mobile entities and propagation of information for routing the service in a mobile environment. Ad hoc Data Dissemination System able to provide an optimised dissemination service for different Communities of Interest CoI. The system handles registration of mobile subscribers and publishers that can join and leave different CoI depending on their rights that can be accessed through the directory system. To cope with the mobility of the Dissemination Nodes on the field, the system dynamically adapts to establish and maintain a Dissemination Overlay Network able to link together the publisher and subscriber for each CoI. As a conclusion, the paper identifies additional challenges under study for dynamic QoS mechanisms in order to provide a deterministic Dissemination Service based on resource reservation mechanisms activated between the Dissemination Overlay Network and the real networks below.
