Abstract
The Internet Engineering Task Force (IETF) has standardized a new framework, called Static Context Header Compression and fragmentation (SCHC), which offers adaptation layer functionality designed to support IPv6 over Low Power Wide Area Networks (LPWANs). The IETF is currently profiling SCHC, and in particular its packet fragmentation and reassembly functionality, for its optimal use over certain LPWAN technologies. Considering the energy constraints of LPWAN devices, it is crucial to determine the energy performance of SCHC packet transfer. In this paper, we present a current and energy consumption model of SCHC packet transfer over Sigfox, a flagship LPWAN technology. The model, which is based on real hardware measurements, allows to determine the impact of several parameters and fragment transmission strategies on the energy performance of SCHC packet transfer over Sigfox. Among other results, we have found that the lifetime of a device powered by a 2000 mAh battery, transmitting packets every 5 days, is 168 days for 2250-byte packets, while it increases to 1464 days for 77-byte packets.
Highlights
In the last years, Low Power Wide Area Network (LPWAN) technologies have gained significant momentum as solutions for providing connectivity to Internet of Things (IoT)devices
We model and evaluate the energy performance of Static Context Header Compression and fragmentation (SCHC) packet fragmentation over Sigfox, a flagship LPWAN technology that supports a severely constrained maximum payload size (i.e., 12 bytes) for IoT device packet transmission
For our model by measuring the current consumption and duration of the states involved the 77-byte SCHC Packet size, such difference ranges from 4 days (Tp_min = 70 min) toin42a transfer on a real Sigfox device
Summary
Low Power Wide Area Network (LPWAN) technologies have gained significant momentum as solutions for providing connectivity to Internet of Things (IoT). Fragmentation and Reassembly (F/R) functionality, such as Sigfox or LoRaWAN, an adaptation layer including F/R support is needed between IPv6 and the underlying LPWAN technology. To this end, the IETF has recently developed a standard called Static Context. Considering the energy constraints of IoT devices (many of which are not mains-powered), it is fundamental to evaluate the energy performance of SCHC fragmented packet transmission. We model and evaluate the energy performance of SCHC packet fragmentation over Sigfox, a flagship LPWAN technology that supports a severely constrained maximum payload size (i.e., 12 bytes) for IoT device packet transmission.
