Tutorial PM2 12.30-15.30:
Wireless Sensor Networks (WSN)

Wireless Sensor Networks (WSN) provide a fundamentally new set of research challenges – involving the development of self-configuration protocols that are energy-efficient, fault-tolerant and scalable. This tutorial aims to synthesize the diverse literature concerning various aspects of sensor networks such as coding, channel access, routing, and self-organization, with emphasis on energy efficient strategies. The tutorial has three major components:

  • Introduction and discussion of physical, coding, medium access control, routing, and transport layer issues as applied to WSNs,
  • Overview of several algorithms and protocols proposed in recent years which address elements of the WSN paradigm such as data centrality, data aggregation, and asymmetric flow of information,
  • A detailed discussion of energy efficient strategies aimed to extend the useful life of WSN. Particular emphasis given to the use of coding and of energy aware MAC and routing protocols.
