Taschenbuch. Condition: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book presents extensive research on two main problems in robotics: the path planning problem and the multi-robot task allocation problem. It is the first book to provide a comprehensive solution for using these techniques in large-scale environments containing randomly scattered obstacles. The research conducted resulted in tangible results both in theory and in practice. For path planning, new algorithms for large-scale problems are devised and implemented and integrated into the Robot Operating System (ROS). The book also discusses the parallelism advantage of cloud computing techniques to solve the path planning problem, and, for multi-robot task allocation, it addresses the task assignment problem and the multiple traveling salesman problem for mobile robots applications. In addition, four new algorithms have been devised to investigate the cooperation issues with extensive simulations and comparative performance evaluation. The algorithms are implemented and simulated in MATLAB and Webots.…

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Résumé: Les réseaux mesh sans fil représentent la technologie sans fil la plus récente. Cependant, la sécurité reste un véritable défi pour cette technologie. Dans ce rapport, nous proposons des solutions pour la sécurité des réseaux mesh sans fil multi-sauts. D'abord, nous avons proposé une extension du mécanisme d'authentification du protocole 802.1x afin de l'adapter à un environnement multi-sauts et en particulier les réseaux mesh. Ensuite, nous avons défini des architectures de réseaux mesh sans fil utilisant le protocole PANA comme mécanisme d authentification et de contrôle d accès. Enfin, nous avons proposé une nouvelle méthode d'authentification EAP particulièrement adaptée à l'environnement des mobiles. Cette méthode a été formellement validée. 68 pp. Französisch.…

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A wireless sensor network designates a wireless network composed of numerous sensor nodes spatially distributed over an area in order to collect information. The sensor nodes communicate wirelessly with each other in order to self-organize into a multi-hop network, collaborate in the sensing activity and forward the acquired information towards a collector node called base station or sink. Due to the collaborative characteristic of such networks, sensor nodes may self-organize into groups to cooperatively monitor environmental conditions or perform tasks. In some critical applications (such as military, healthcare, etc.), information exchanged between group members (sensor nodes) needs to be secured. Therefore, a Secure Group Communication (SGC) scheme must be applied to protect the communication inside the group from potential attacks (such as eavesdropping, injecting, modifying messages, etc.). Moreover, the secure group communication scheme must address the group membership operations (new sensor nodes may join the group, and current sensor nodes can leave the group) to avoid potential attacks such as impersonation, denial-of-service, unauthorized access, etc. 160 pp. Englisch.…
