Improving Redundancy in LoRaWAN for Mixed-Criticality Scenarios

CAPL: Criticality-Aware Adaptive Path Learning for Industrial Wireless Sensor–Actuator Networks

“…A key to the solution of the exploration-exploitation trade-off in CAPL is the criticality for control. There exist substantial studies to improve industrial system performance by applying the conventional concept of criticality in the IWSAN [10], [11], [12], [13]. The existing studies on the so-called mixed-criticality IWSAN assign the type-dependent criticality to each flow or traffic that occurs in an environment, where several types of applications coexist.…”

“…For example, system mode change schemes based on network conditions are proposed in [10] and [11] to guarantee the requirements of high-criticality traffic or flow. Moreover, the criticality-based MAC protocols are proposed in [12] and [13], which classify traffic in the IWSAN into three categories: safety, control, and monitoring. However, these studies determined the level of criticality considering the characteristics of the traffic type.…”

“…To properly consider the exploration-exploitation trade-off in the IWSAN path selection, the concept of criticality for control is incorporated into our formulation, and an appropriate algorithm is developed for CAPL. It should be noted that the packet criticality for control dynamically changes with respect to the state of the physical system, which is fundamentally different from the conventional concept of criticality with respect to the type of information [10], [11], [12], [13]. To minimize QoC degradation caused by exploration, CAPL performs exploration depending on the level of criticality of the control packets, where the criticality of a packet is determined by the degree of QoC degradation caused by the loss of the corresponding packet.…”

Resilient Edge: Building an Adaptive and Resilient Multi-Communication Network for IoT Edge Using LPWAN and WiFi

“…They utilized message replay and checkpoint-based mechanisms to make client-edge-server systems more tolerant to edge failures and client mobility. Carvalho et al [66] implement a replication mechanism LoRa-REP for replicating critical messages on LoraWAN by sending them at different SF and improving redundancy in LoRaWAN for mixed-criticality scenarios.…”

A Complete Key Management Scheme for LoRaWAN v1.1

“…Also, the current key updating scheme is not clearly defined [ 7 ]. Key back-up, recovery, revocation, and handling of backward compatibility issues [ 21 , 22 , 23 , 24 ] are existed in the current version. Those issues make the key management security framework vulnerable.…”
