Problem description: A wireless sensor network or WSN has three main components, the sensor node, the access point and a console. These components exist for the purpose of making the WSN function as we want to, collecting sensor values, monitoring shipments or tracking animals. Many articles concern themselves with the topic of energy consumption in sensor nodes or wireless sensor networks, which can be logical because the sensor node is in many cases only powered by a coin cell battery, and that replacement of the battery once deployed can in many scenarios be difficult.

This thesis will include a theoretical part concerning the technology behind a WSN such as the IEEE, the OSI model, Internet Protocol and routing in general. Furthermore, the focus will be on differentiating factors for the energy consumption in the wireless sensor nodes.

The protocols researched are WirelessHart and RPL. WirelessHart seem to be the choice when dealing with industrial wireless sensor networks where the nodes are fixed to a certain point where it is supposed to measure a value. RPL must be more flexible as thought to be applied in many different systems and aspects and the nodes running RPL can be dropped in for example terrain and be expected to form a network.

Methods and Tools: The tools and methods in this thesis are based on
  • A set of scenario, describing the challenges
  • A list of requirements being extracted from the scenarios
  • A description and evaluation of technologies and tools being candidates for solutions
  • A functional architecture/description of the envisaged system
  • An implementation of the core concepts
  • A demonstration of the solution
  • An evaluation of the solution, including a critical review of the descisions taken earlier
  • Conclusions
  • References
Time schedule The envisaged time schedule (for a long thesis/60 ECTS) is:
T0 0 starting month, T0+m denotes the month where the contribution to a certain chapter shalle be finalized
T0+2 months: create an initial page describing the scenario
T0+3: Provide a list of technologies which you think are necessary for the thesis
T0+4: Establish the table of content (TOC) of the envisaged thesis. Each section shall contain 3-10 keywords describing the content of that section
T0+7: Provide a draft of section 2 (scenario) and 3 (technologies)
T0+10: Establish a draft on what to implement/architecture
T0+11: Set-up an implementation, testing and evaluation plan
T0+15: Evaluate your solution based on a set of parameters, keep in mind there is no such thing as a free lunch
T0+17: Deliver the thesis
Pre-Knowledge This thesis includes a reasonable amount of programming. The envisaged thesis is based on radio communications, thus expects the user to have followed at least two radio-related courses
