چکیده
Long-range wide-area network (LoRaWAN) is one of the most promising IoT technologies that are widely adopted in low-power networks (LPWANs). LoRaWAN faces scalability issues due to a large number nodes connected same gateway and sharing channel. Therefore, LoRa seek achieve two main objectives: 1) successful delivery rate 2) efficient energy consumption. This article proposes novel game-theoretic framework for named best equal (BE-LoRa), jointly optimize packet ratio efficiency (bit/Joule). The utility function node defined as throughput transmit power. act rational users (players) which maximize their utility. aim BE-LoRa algorithm while maintaining signal-to-interference-and-noise-ratio (SINR) each spreading factor (SF). power allocation implemented at server, leads an optimum SINR, SFs, transmission settings all nodes. Numerical simulation results show proposed has significant improvement compared adaptive data (ADR) legacy LoRaWAN. For instance, very dense (624 nodes), can improve by 17.44% reduce consumed 46% ADR.

Fair Adaptive Data Rate Allocation and Power Control in LoRaWAN
In this paper, we present results of a study of the data rate fairness among nodes within a LoRaWAN cell. Since LoRa/LoRaWAN supports various data rates, we firstly derive the fairest ratios of deploying each data rate within a cell for a fair collision probability. LoRa/LoRaWAN, like other frequency modulation based radio interfaces, exhibits the capture effect in which only the stronger signa...

متن کاملOptimizing Elastic IoT Application Deployments
Applications in the Internet of Things (IoT) domain need to integrate and manage large numbers of heterogenous devices. Traditionally, such devices are treated as external dependencies that reside at the edge of the infrastructure and mainly transmit sensed data or react to their environment. Recently however, a fundamental shift in the basic nature of these devices is taking place. More and mo...
متن کاملPower Allocation In Cooperative Relay Channels
This paper concerns power allocation in relay-assisted wireless channels for two-hop transmission. First, the transmitter sends the information to both the relay and receiver parts. Next, in the second hop, the transmitter cooperates with the relay to increase the received signal to noise ratio (SNR), assuming the relay makes use of the Amplify and Forward (AF) strategy. Moreover, it is assumed...
