The adoption of LoRaWAN as a technology for wireless deployments in many applications, such smart cities or industry 4.0, still presents challenges energy consumption, robustness, reduced throughput harsh, noisy scenarios. Class B is MAC mode that allows better performance downlink traffic but has difficulties regarding scalability and its response to channel interference. This article introduc...

One such development is fourth generation networks. Also called future or Next Generation Networks. The introduction of 4G has widened the scope mobile communication. Now not only a device used for talking but its more less portable computer that can serve different purposes. offers higher data rates with seamless roaming. user communicate without any disturbance while switching his coverage ne...

The introduction of low-power wide-area networks (LPWANs) has changed the image smart systems, due to their wide coverage and characteristics. This category communication technologies is perfect candidate be integrated into inverter control architectures for remote microgrid (MG) applications. LoRaWAN one leading LPWAN technologies, with some appealing features such as ease implementation possi...

In wireless sensor networks, optimal consumptionof energy and having maximum life time are important factors. In this article attempt has been made to send the data packets with particular reliability from the beginning based on AODV protocol. In this way two new fields add to the routing packets and during routing and discovering of new routes, the lowest remained energy of nodes and route tra...

Due to the increasing use of wireless communications, infrastructure-less networks such as Delay Tolerant Networks (DTNs) should be highly considered. DTN is most suitable where there is an intermittent connection between communicating nodes such as wireless mobile ad hoc network nodes. In general, a message sending node in DTN copies the message and transmits it to nodes which it encounters. A...

Low Power Wide Area Network (LPWAN) technologies have been exponentially growing because of the tremendous growth Internet Things (IoT) devices across globe. Several LPWAN utilized by researchers to address certain issues like increased number collisions, retransmissions, delay, and energy consumption. However, Long Range (LoRaWAN) is most suitable attractive technology in terms delay optimizat...

mobile-ad-hoc-networks (manets) are self-configuring networks of mobile nodes, which communicate through wireless links. the infrastructure of a mobile ad hoc network (manet) has no routers for routing, and all nodes must share the same routing protocol to assist each other when transmitting messages. the main issues in manets include the mobility of the network nodes, the scarcity of computati...
