Etude et conception d'algorithmes pour les réseaux mobiles et ad-hoc

Abstract : Advances in mobile and wireless networks have made fourth generation networks development possible. 4G networks promote the concept of the always best connected and served (ABC&S) paradigm. The ABC&S paradigm envisages that mobile terminals will stay connected: anywhere & anytime. Our work consists on conception of a wireless overlay network structure and scheme for handoffs. The primary technical challenges in the design of a seamless handoff are: low latency and packet loss. The ad hoc networks are considered as a generalization of the wireless networks because the role of the fixed infrastructure is limited. Recently, significant progress to study QoS in the mobile ad hoc networks has been made. This thesis presents a critical vision of interesting work in this field. The strong and weak points of each proposal are exploited to carry out a complete QoS model. This model uses a QoS routing protocol to find the best paths for each flow according to its QoS requirements an admission control and reservation are used to prevent the network overload without mobility.
