“…In general, end nodes now have to spend more time awake, listening to transmissions from other nodes and forwarding packets towards their destination. Some of the surveyed proposals consider this issue and develop strategies to minimize energy consumption (e.g., synchronized, daisy-chain-like wake/sleep cycles) [11], [12], [15]. However, others simply assume devices will be constantly awake and powered, impeding maintenance-less, long-term battery operation [17], [14], [13].…”

LoRa has emerged in recent years as a wireless technology providing long-range communication for-low power Internet of Things (IoT) devices. The LoRaWAN architecture adds the Medium Access Control (MAC) and application layers and defines a star of stars topology suitable for many and diverse IoT applications. However, in a number of scenarios, a more flexible network topology than LoRaWAN's is needed. We review the state of the art of the design and implementation of multihop and mesh solutions for LoRa and LoRaWAN. We discuss the remaining challenges for multi-hop and mesh solutions to overcome in order to unlock the opportunities that decentralized, self-organizing and infrastructure-less LoRa networks can bring to IoT applications.

LoRa technology enables long range, low power consumption and secure data transmission features. By multi-hop communication, we argue that LoRa is potentially very useful for the monitoring system for wide area with long distance. In this paper, we propose a protocol with reliable multi-hop communication for linear network including network constructing period and data operating period using LoRa. Also, we analyze and show the tradeoffs among synchronization time interval, clock drift rate and configurations in LoRa. Our experimentation using five nodes can form a linear network and delivery reliability achieves above 95% in case of adapting one-time retransmission.

“…While most implementations built with these technologies are single-hop networks used to connect only end-devices to gateways and relying on the Internet for the remaining part, there are examples of multi-hop networks based on LoRa. In [23], a multi-hop linear network is deployed, with nodes forming a line topology and packets travelling from a node to the next in the line. In [24], the focus is on the effects of concurrent transmission in a multi-hop network, in order to ensure network reliability.…”

LoRa (Long Range) is a proprietary radio communication technology exploiting license-free frequency bands, allowing low-rate information exchange over long distances with very low power consumption. Conventional environmental monitoring sensors have the disadvantage of being in fixed positions and distributed over wide areas, thus providing measurements with a spatially insufficient level of detail. Since public transport vehicles travel continuously within cities, they are ideal to house portable monitoring systems for environmental pollution and meteorological parameters. The paper presents a feasibility analysis of a Wireless Sensor Network (WSN) to collect this information from the vehicles conveying it to a central node for processing. The communication system is realized by deploying a layer-structured, fault-resistant, multi-hop Low Power Wide Area Network (LPWAN) based on the LoRa technology. Both a theoretical study about electromagnetic propagation and network architecture are addressed with consideration of potential practical network realization.
