Problem description: The growing trend of utilizing solutions featuring Wireless Sensor Networks (WSN) for various applications in industrial, medical and commercial domains introduces a set of challenges for the underlying protocols used to enable these networks. Sensor nodes in a WSN have a limited amount of energy available and are often deployed in unpredictable environments which makes energy efficiency and effective sharing of the wireless medium a very important concern. The IEEE 802.15.4e amendment to the IEEE 802.15.4 Standard for Low-Rate Wireless Networks aims to address the issues related to WSN for devices running the 802.15.4 stack, by introducing several general enhancements at the MAC layer and a new set of MAC “behavior modes”. These are different access schemes for the MAC layer that enable support for various applications with stringent requirements in terms of latency, reliability and timeliness (such as process automation and control, smart utility, and infrastructure monitoring networks). Time Slotted Channel Hopping (TSCH) is among the new MAC modes introduced in the 4e amendment. It is considered one of the more interesting additions of the amendment and is meant to satiate the requirements of various WSN applications such as those found in healthcare and industry, as well as in commercial domains. TSCH combines time slotted access with multi-channel and channel hopping capabilities, which allows for networks with higher throughput, deterministic latency and low energy usage, as well as increased network capacity with reduced impact of interference and multipath fading [2]. According to [3], TSCH is currently considered the de-facto technology for highly reliable, low-power wireless sensor networking technology, and is also found in commercial solutions like WirelessHART and ISA100.11a
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
