Overview and Measurement of Mobility in DASH7

Abstract : Recently, the evolution of low-power wide area networks (LPWANs) provides Internet of Things (IoT) with an approach between the short range multi-hop technology and the long-range single-hop cellular network technology. LPWANs provide connectivity by using long-range communication with low data rate in unlicensed bands. They are developed to satisfy the requirements of IoT communication needs, but less attention is given to the mobility of the End-Devices (EDs). In this paper, we consider DASH7 which is a well-defined LPWAN standard provided by DASH7 Alliance. After a brief overview of this technology, we focus on EDs mobility to show how the mobility can be achieved while transmitting data. An appropriate testbed is setup for testing. Experimental results show the mobility delay time for an ED to switch between two gateways (GWs).
