Learning Objectives

  • Peer to peer and wireless networks

    Knowledge and understanding: the aim of the course is to acquire advanced knowledge that allow the student to understand theoretical mechanisms which constite the base for a distributed communication protocol; in detail, the student will acquire knowledge of main P2P and wireless networks protocols.

    Applying knowledge and understanding: student will acquire knowledge usefull to design a distributed coordination protocols specific for an Overlay Network, defining suitable feature to promote collaboration, optimizing , at the same time, the exploitation of the shared resources. For this reason, a part of the course will be held in laboratory, with lessons dedicated to the study of the NS2 simulator, in order to allow performance evaluation of a network protocol.

    Making judgements: the study cases presented, based on real network protocols, will allow the student to discover limits and errors of their design; this will be the basis for autonomously developing of new solutions, going beyond restrictions due to scalability in distributed systems.

    Communication skills: student will acquire advanced communication skills using technical language in the field of network protocols and distributed systems.

    Learning skills: the course provides, to the student, teoretical and practical methodologies in order to deal with new problems that can rise during designing activity.
