Communications and Networks (Undergraduate)

This compulsory module covers the basic concepts in communications and networks. 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)



Research 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
