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].

Comments
Red line
Your thesis should have a "red line", which is visible throughout the whole thesis. This means you should mention in the beginning of each chapter how the chapter contributes to the "goals of the thesis".
Use of scientific methods
A thesis follows a standard method:
- describe the problem (problemstilling)
- extract the challenges. These challenges should be measurable, e.g. method is too slow to be useful to voice handover.
- Analyse technology with respect to challenges. Don't write & repeat "everything" from a certain technology, concentrate on those parts (e.g. protocols) which are of importance for your problem
References
- Wikipedia is good to use to get an overview on what is happening. But there is not scientific verification of Wikipedia, thus you should use wikipedia only in the introduction of a chapter (if you use text from wikipedia). Use scientific literature for your thesis.
- Scientific library is "at your hand", you can get there directly from UiO: [[How to get access to IEEE, Springer and other scientific literature -> Unik/UiOLibrary]]
- I suggest that references to web pages, e.g. OASIS, W3C standards, are given in a footnote. Only if you find white papers or other .pdf documents on a web page then you refer to them in the reference section.
Evaluation of own work
Perform an evaluation of your own work. Revisit the challenges and discuss in how you fulfilled them. Provide alternative solution and discuss what should be done (or what could have been done).
