Algorithme de routage coopératif à qualité de service pour des réseaux ad hoc agri-environnementaux

Abstract : To have an agriculture guaranteeing its good practices and thus, contributing to the environmental protection is a major issue of the sustainable development of rural areas. For that, it is necessary to be able to supervise the environment and to record the agricultural interventions. This monitoring requires to collect space-time data to supply the agrienvironmental information systems enable to build indicators allowing to take decisions, to provide controls... Data acquisition can be effective only if it is carried out in an automatic way through communication networks. Thus, within the framework of this work, the concept of agrienvironmental networks is presented. The characteristics and the constraints related to these kind of networks show that only the ad hoc wireless networks can be implemented to meet the needs. A state of the art of the ad hoc networks and the associated routings protocols shows that the creation of a new cooperative routing protocol is necessary in order to satisfy the agri-environmental network needs. This cooperative routing protocol is the principal contribution of this work. Then, the question of the Quality of Service in this kind of wireless networks is very important, in particular in a context of environment monitoring. Within the routing protocol suggested, the Quality of Service is approached according to several principles : estimate of the available bandwidth, improve of the network connectivity... The Quality of Service in the agri-environmental networks is thus another important point of this thesis work. The implementation of these principles is illustrated through various examples of agrienvironmental networks. This aspect is approached on the whole by the implementation of original modules as well on the hardware level as software. The proposed solutions allow to deploy fixed or mobile sensors, able to supervise the environment and thus, to understand better the man's intervention.
