Design, implementation and evaluation of an energy efficient RPL routing metric

In this thesis I proposed, developed and tested a new RPL routing metric based on the energy consumption of the nodes of a network. The network has a particular feature, i.e. the sensors are low power. This nodes are realized using the specifications of the new technology arises in the last years: the Internet of Things. The routing protocol is RPL, and 6LowPAN standard is introduced. I developed the routing metric using the operative system Contiki, and i tested it with the low power networks simultator Cooja. I named my routing metric ENTOT, and i compared it with ETX, one of the most efficient routing metric.

The thesis is structured as follows.
In Chapter 1 we provide an overview over Smart Objects networks, particularly describing what are the main features of low power networks, and what are the routing requirements for this type of networks.
In Chapter 2 is explained in detail how RPL protocol is designed, what are the steps to design a RPL routing metric, an example of a routing metric (ETX), and is mention ContikiRPL, the RPL version implemented in this operating system.
In Chapter 3 it is described how the energetic model and the routing metric based on the energy consumption (ENTOT) are implemented in Contiki.
Finally, in Chapter 4 we compare and evaluate the performance of ETX and ENTOT metric in a RPL scenario.
