Suggested Reference (level of competency expected): current EE506 text


Area III: Communication Networks

Link-level ARQ schemes (Stop-and-wait, go-back-N, selective repeat).

Elementary queueing models for networks (M/M/1, M/G/1, M/M/K/K, etc.). Queueing networks. Random Multiaccess schemes and their performance (e.g. Aloha, CSMA, splitting algorithms).
