The number of devices connected to the Internet is growing substantially as a result of increased realization of the Internet of Things (IoT) concept. As cellular networks can already be perceived almost as ubiquitous, they can potentially provide IoT systems access to the Internet regardless of their location. However, increased use of commercial cellular networks to provide connectivity for IoT systems would also change the traffic mix of these networks. It has been measured earlier that a large number of small packets are challenging for different wireless access networks to provide high performance. Currently, small packets are transmitted, for example, with Voice over IP (VoIP) services. Many IoT applications, being based on constrained sensor devices and Machine-to-Machine (M2M) type of communications, can increase the number of small packets significantly. In this paper, we measure the performance of Long …
