Abstract

|
|
|
| LoRWAN nodes can be localized using the TDoA (Time Difference of Arrival) approach. A big advantage is that the geo-location does not consume a lot of energy when compared to GPS approaches. Depending on the use case, the accuracy of the geo-localization (200m) might be a disadvantage. Therefore we propose activating an E-compass in the LoRa node and frequently communicating this directional information over the LoRaWAN network. This extra information can then be fused with TDoA in a map matching algorithm to improve the estimations. We show that our sensor fusion technique is 8 times more accurate than raw TDoA at the cost of only embedding a low-cost e-compass. |
