Internet of things and implementation of local wireless sensor network

Abstract [en]

This master’s thesis covers the research and development of a local wireless

sensor network with capabilities for IoT (internet of things) applications and with

the ability to monitor and automatically control a watering system with soil

humidity as input. The goal with this thesis was to develop a system where the

wireless communication within the local network is suited for low power and lossy

networks (LLN). The system was to be controlled and monitored from a user

interface which is available from the internet.

A system was developed with a wireless network with a suited underlying network

stack with protocols that was fitted for the constrained environment. The nodes

send values to a website with a UI (user interface) where values can be monitored

and the user can control the system and send values to specific nodes within the

system. The sensor nodes communicate with protocols developed for low power

networks and an edge router was built for the purpose of routing this network to

the internet.

Research in the internet protocol suite has come a long way and a large variety of

protocols has been developed to fit almost every set of nodes with different

battery lifetime, processing power, and memory size. This thesis shows that the

communication stack can be modelled with suited protocols to be satisfactory for

different internet of things applications with high energy efficiency.
