Long-Range Wide-Area Network (LoRaWAN) enables flexible long-range service communications with low power consumption which is suitable for many IoT applications. The densification of LoRaWAN, needed to meet a wide range networking requirements, poses further challenges. For instance, the deployment gateways and devices are widely deployed in urban areas, leads interference caused by concurrent ...

The Internet of Things (IoT) is a concept in which everyday objects and devices are equipped with connectivity, allowing them to exchange information. In recent years, interest this has increased led the creation numerous applications interested customers. Long Range (LoRa) technology part technologies that support IoT equipment LoRa popularity due its ability work low power consumption, very i...

In recent years a new type of wireless networks named wireless mesh networks has drawn the attention of researchers. In order to increase the capacity of mesh network, nodes are equipped with multiple radios tuned on multiple channels emerging multi radio multi channel wireless mesh networks. Therefore, the main challenge of these networks is how to properly assign the channels to the radios. O...

New innovations, technologies, ideas and businesses are driving the realisation of the Internet of Things (IoT) vision. As with many other fields in technology comes competing protocols and standards, ranging from modulation schema used for transmitting data to security standards used to ensure safe operation and the privacy needs for all involved entities. This thesis looks into one of the com...

in recent years mobile networks have expanded dramatically, compared with other wireless networks. routing protocols in these networks are designed with the assumption that there is no attacker node, so routing protocols are vulnerable to various attacks in these networks. in this paper, we review the network layer attacks and then we simulate the impact of black hole attack on ad hoc on demand...

LoRaWAN deployments follow an ad-hoc deployment model that has organically led to overlapping communication networks, sharing the wireless spectrum, and completely unaware of each other. uses ALOHA-style where it is almost impossible schedule transmission between networks belonging different owners properly. The inability will cause inter-network interference, which increase node-to-gateway mes...

In this study, we present an application-dependent heterogeneous LoRa network. Previous studies on LoRaWAN and particularly that rely the use of adaptive data rate to optimize performance network are based purely path loss nodes in with assumption all have similar requirements terms latency. a real-life full-scale deployment, is unlikely be case as current deployment trend shows practical imple...

Many appealing multicast services such as on-demand TV, teleconference, online games and etc. can benefit from high available bandwidth in multi-radio multi-channel wireless mesh networks. When multiple simultaneous transmissions use a similar channel to transmit data packets, network performance degrades to a large extant. Designing a good multicast tree to route data packets could enhance the...
