Multi-path load balancing routing over a network that combines multi-hop short range and single-hop long-range wireless sensor networks


LoRa is an emerging Low-Power Wide-Area Network (LPWAN) technology. In Belgium, a commercial solution on a national scale is being deployed by Proximus. Private and cooperative LoRa networks also exist, the most popular being The Things Network. Indeed, LoRa is an innovative networking technology with a bright future for lightweight IoT applications, especially for sensors.
Our research group has included the LoRa networking technology into existing wireless sensor networks, which primarily operate on top of IEEE 802.15.4 (ZigBee radio). This has created a lot of new research options such as running an IoT IPv6 protocol stack with RPL routing on top of LoRa instead of the default LoRaWAN protocol stack.
Having a Wireless Sensor Network combination using short-range IEEE 802.15.4 radio technology combined with a long-range LPWAN technology is particularly interesting from a routing perspective. It allows reaching the destination via a single-hop low-bandwidth LPWAN with 1% transmission restriction, via a multi-hop higher-bandwidth IEEE 802.15.4 links, or via a hybrid approach respecting this 1% transmission restriction.

Kind of work

You will work with on the Contiki lightweight IoT operating system on top of the Zolertia Re-Mote platform. The essential code for transmitting/receiving over the IEEE 802.15.4 and a long-range radio (integrated CC1200 radio, or external LoRa radio) and a modified dual-radio RPL IPv6 routing protocol for Low-Power and Lossy networks is provided. It is your task to further modify the RPL objective function to select the “best” while adhering to the 1% long-range restriction.

Framework of the Thesis

This thesis is proposed in the context of the current IoT projects (EU and collaboration with industry) of the smartnets group.
