Abstract
In this paper, we introduce the original Mobile Intelligent System (MIS) in embeded FPGA architecture. This node will allow the construction of autonomous mobile network units which can move in unknowns, inaccessible or hostile environnement for human being, in order to collect data by various sensors and transmits them by routing to a unit of distant process.
 In the sake of improving the performance of transmission, we propose a global schema of QoS management using DiffServ/MPLS backbones. We provide an evaluation of several scenarios for combining QoS IP networks with MIS access network. We conclude with a study on interoperability between QoS patterns in access and backbone networks.
Highlights
Sensors become necessary elements in all systems where information resulting from the external environment is necessary to evaluate and act
We present the architecture of Mobile Intelligent System (MIS) and the study of some problems associated with QoS in MIS interconnected with wired QoS IP networks using Diffserv or/and MPLS
The second section focuses on the functional architecture and the experimental MIS platform and its units; Section 3, presents the concept of quality of service, we present the pillars of QoS in IP networks: DiffServ and MPLS
Summary
Sensors become necessary elements in all systems where information resulting from the external environment is necessary to evaluate and act. Each node is composed principally of one or several sensors, a processing unit and a module of communication, etc These nodes communicate between each other according to the network topology and the existence or not of an infrastructure (access points) to forward the information to a control unit outside the zone of measure. All these features enable us to imagine an adaptive complex system built around several sensors in a wireless communication system. To provide flexible services with a guarantee of performance parameters as: delay, jitter, bandwidth rates and packet loss, the IP networks must necessarily incorporate a concept of prioritization and control admission in the network These QoS concepts must be available in all areas and access crossed networks.
