It introduces the concept of a communications system and then focusses on specific elements. It covers circuit and switched versus packet switched networks, and the ISO/OSI 7 layer model. Also covered are certain critical network protocols, e.g. TCP/IP and CSMA/CD, key Internet concepts, converged networks, and mobile networks. Introductory Java Programming (BUPT joint programme) ResearchResearch Interests: Improving Quality of Experience (QoE) in LTE networks specifically related to bufferbloat issues Performance evaluation of IP networks specifically related to non-FIFO scheduling and differentiated services Green networking - saving energy in the core and access networks while maintaining QoS Virtual testbeds, e.g. currently working with Juniper Networks on employing their virtual router platform (Junosphere) and supporting SDK in enhancing networking research and teaching at QMUL Click here for more.Publications Ai T, WIJERATNE VA, Wahid A (2015).
