IEEE 802.15.4e Time Slotted Channel Hopping (TSCH) standard has gained a lot of attention within the Industrial Internet of Things research community due to its effectiveness in improving reliability and providing ultra-low power consumption for industrial applications, and in which its communication is orchestrated by a schedule. Despite its relevance, the standard leaves out of its scope in defining...
In Wireless Sensor Network (WSN) applications such as environment monitoring, building monitoring, etc., sensor nodes collect data and send it to the base stations or sinks for analysis. As the networks grow in scale, it necessitates using multiple sinks in the network. In here, throughput capacity and the average delay of WSN with multiple sinks, which are two main quantity of interest, has been...
A system using frequency offset based transmit-reference (TR) modulation allows multiple nodes to transmit simultaneously and asynchronously without any mutual timing coordination. Thus, such a system provides inherent capabilities for a multiple access in the medium access control (MAC) layer to coordinate the shared use of the common wireless medium among the nodes of the wireless sensor network...
This paper proposes QoS-constrained energy-efficiency (EE) maximization scheme in a multi-antenna wireless powered network.
