چکیده
In this paper, we investigate a relaying wireless sensor network (WSN) with the non-orthogonal multiple access (NOMA) and node selection schemes over Rayleigh fading. Precisely, system consists of two clusters, sink node, an amplify-and-forward (AF) relay. These sensors applying NOMA transmit sensing data from clusters via relay to sink. We derived expressions outage probability throughput for nodes. also provide numerical results examine behavior system. Finally, verify validity our analysis by using Monte-Carlo simulation.

Non-Orthogonal Multiple Access for Ubiquitous Wireless Sensor Networks
Ubiquitous wireless sensor networks (UWSNs) have become a critical technology for enabling smart cities and other ubiquitous monitoring applications. Their deployment, however, can be seriously hampered by the spectrum available to the sheer number of sensors for communication. To support the communication needs of UWSNs without requiring more spectrum resources, the power-domain non-orthogonal...
متن کاملGeographic and Clustering Routing for Energy Saving in Wireless Sensor Network with Pair of Node Groups
Recently, wireless sensor network (WSN) is the popular scope of research. It uses too many applications such as military and non-military. WSN is a base of the Internet of Things (IoT), pervasive computing. It consists of many nodes which are deployed in a specific filed for sense and forward data to the destination node. Routing in WSN is a very important issue because of the limitation of the...
متن کاملTopology Control in Wireless Sensor Network using Fuzzy Logic
Network sensors consist of sensor nodes in which every node covers a limited area. The most common use ofthese networks is in unreachable fields.Sink is a node that collects data from other nodes.One of the main challenges in these networks is the limitation of nodes battery (power supply). Therefore, the use oftopology control is required to decrease power consumption and increase network acce...
متن کاملNon-Orthogonal Multiple Access Schemes with Partial Relay Selection
In this paper, non-orthogonal multiple access (NOMA) in amplify-and-forward relay systems with partial relay selection (PRS) is investigated. More specifically, new exact closed-form expressions for the outage probabilities at two users are derived, based on which an asymptotic analysis at high signalto-noise ratio (SNR) is carried out. Additionally, in order to investigate the performance gap ...
متن کاملWireless sensor network design through genetic algorithm
In this paper, we study WSN design, as a multi-objective optimization problem using GA technique. We study the effects of GA parameters including population size, selection and crossover method and mutation probability on the design. Choosing suitable parameters is a trade-off between different network criteria and characteristics. Type of deployment, effect of network size, radio communication...
