CS345/912 Sensor Networks and Mobile Data Communications


CS345 15 CATS (7.5 ECTS) Term 1


Option - CS, CSE


CS241 Operating Systems and Computer Networks

Academic Aims

The aim of the module is to equip students with a fundamental understanding of sensor networks and mobile ad hoc networks, including the domains in which associated technologies have been applied. The emphasis of the module is on the efficiency and practicality of such protocols in sensor networks and ad hoc mobile networks.

Learning Outcomes

By the end of the module, a student should be able to:

  • Understand the principles of sensor networks and mobile ad hoc networks, and their impact on protocol design
  • Develop MAC and routing protocols for sensor and mobile networks
  • Develop efficient protocols for sensor and mobile networks
  • Understand and develop information dissemination protocols for sensor and mobile networks


  • Motivation and applications
  • System architecture and Sensors
  • Media access control protocols - TDMA, duty cycling, SMAC, XMAC, IEEE802.11/15, CSMA/CA, RTS/CTS
  • Routing: directed diffusion, communication patterns, proactive/reactive/hybrid ad hoc routing, geographic routing
  • Energy efficiency in sensor networks: duty cycling, clustering, topology control
  • Network reprogramming techniques
  • Delay tolerant networks - optimistic routing, social net-based routing
  • Communicaiton protocol security characteristics
  • Mobility models
  • Vehicular networks - routing, broadcast, gossip
