A Preamble Sampling Scheme Based MAC Protocol for Energy Harvesting Wireless Sensor Networks

Relay node selection scheme and deep sleep period for power management in energy‐harvesting wireless sensor networks

“…The major concern of the EEMEHWSN is that it cannot ensure communication in the EH‐WSN in the event that there are not enough awake forwarding nodes, either because the density of the nodes in service is too low or that the average energy harvesting period is too long. Therefore, our objective in this work is to expose another new dedicated scheme for mobile EH‐WSN and which represents a prelude to the invention of another protocol of the Delay Tolerant Network (DTN) type [31] in order to mitigate intermittent communication in the network. In Bengheni et al [18], a Preamble sampling Scheme based MAC protocol for Energy Harvesting WSNs (PS‐EHWSN) is proposed. The PS‐EHWSN scheme allows each sensor node within the WSN to determine its incoming sleep interval by using its remaining energy, which can increase over time, enabling it to be able to regulate between its energy consumption and its harvest.…”

“…In this paper, we present a Relay node selection scheme and Deep sleep period for power management in Energy Harvesting Wireless Sensor Networks (RD‐EHWSN) that represents an improvement of PS‐EHWSN [18], where a new unit has been added to each sensor node to help it collect energy; in addition, the transmission amid these sensor nodes is carried out through transmitting numerous short preamble after examination of the channel where the transmitter node has an essential function of transmission. The motivator gets advanced functionalities of the transmitter‐initiated systems from the preceding workings [11, 12].…”

ETI-MAC: An Energy-Harvested Transmitter-Initiated MAC Protocol for Wireless Sensor Networks

“…A MAC protocol for Energy Harvesting WSNs (PS-EHWSN) based on a Preamble sampling Scheme is described in [26]. The PS-EHWSN system enables each sensor node inside the WSN to decide on its approaching sleep interval by utilizing its residual energy, which can rise with time, allowing it to be able to balance between its energy collection and consumption.…”

“…The ETI-MAC protocol is compared to the PS-EHWSN [26] protocol, which uses a dynamic duty-cycle like ETI-MAC and also to a static duty-cycle scheduling scheme BMAC [12], which is the basis of all protocols based on communication through preamble sampling using extensive simulations utilizing the OMNeT++ simulator with the MiXiM framework. To compare the two protocols, the performance measures listed below were used.…”

“…Section III explains the functioning of ETI-MAC protocol, while Section IV discusses the simulation-related material, including the tools and parameters. In Section V, the performance of the ETI-MAC protocol is assessed and contrasted with the PS-EHWSN scheme [26]. In Section VI, conclusions and future research areas are presented.…”
