An undesirable side-effect of network densification is a reduced quality of service due to increased contention. One interesting solution to address this issue is full-duplex medium access control (MAC) with collision detection. By detecting collisions early on, a considerable amount of energy can be saved in dense networks. However, when traffic demand and, as a result, the collision rate decrease,...
Low power wide area networks are gaining interest to connect thousands of nodes to the internet of things. However, because the link budget in these networks is huge, nodes suffer from a near-far effect. Nodes far from the base station cannot send to the base station succesfully when closer nodes are transmitting, causing destructive collisions. LoRa, the considered technology in this paper, is a...
Long range low power is a family of technologies promising to connect thousands of sensors to the future internet of things. Within this family of possible technology choices, two different branches have emerged: the standards based on spreaded wideband communication and the standards based on narrowband communication, both promising to reach long range connectivity at very low power. More specifically,...
A broad range of emerging applications require very low power, very long range yet low throughput communication. Different standards are being proposed to meet these novel requirements. In this paper, the technical differences between a wideband spread spectrum (LoRa-like) and an ultra narrowband (Sigfox-like) network will be explained and evaluated. On the physical layer, simulation results show...
