Embodiment Construction

[0042] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0043] refer to figure 1 and figure 2 , a linear transmission scheduling method suitable for energy harvesting wireless sensor networks, the implementation of this method can maximize the long-term average transmission revenue and ensure the transmission reliability in wireless sensor networks. The present invention is based on different system states (such as figure 1 shown), a threshold strategy is proposed to schedule the data transfer and manage the acquired energy by considering the data storage state and the energy storage state separately, and for each case by maximizing a newly introduced conditional expected payoff, obtained by The optimal transmission threshold, furthermore, proposes a low-complexity method to compute the threshold by linear rotation. The invention obtains the optimal transmission threshold by maximizing a newly introduced condi...

Abstract

The invention provides a linear transmission scheduling method suitable for an energy collection type wireless sensor network. The method comprises the following steps: 1) in a time slot energy collection communication system consisting of a pair of transmitters and receivers, defining a system state according to data and energy; 2) calculating a conditional expected revenue of the transmission process when there are i data packets in the data system; 3) calculating the conditional expected revenue of the transmission process when there are j energy packets in the energy system; and 4) calculating an optimal threshold (the formula is described in the specification) of the transmission process when there are i data packets in the data system, and calculating the optimal threshold (the formula is described in the specification) of the transmission process when there are j data packets in the data system. The invention provides a threshold transmission scheduling strategy and a thresholdcalculation algorithm, the energy obtained by arranging the data transmission and management maximizes the long-term average transmission revenue, and the transmission reliability in the wireless sensor network is ensured.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a communication system with energy collection and a threshold-based transmission scheduling method for energy collection sensor nodes. Background technique [0002] With the extensive development of wireless communication technology, wireless communication technology has penetrated into every aspect of human life. Currently, wireless sensor networks have been widely deployed for the Internet of Things, including environmental control, object tracking, health monitoring, etc. However, these ubiquitous cable-less sensor nodes are usually constrained by limited energy due to sensing and wireless communication. To this end, energy harvesting (EH) technology has currently been proposed as a solution to the energy consumption in wireless sensor networks. Specifically, sensor nodes are powered by ambient energy, such as solar energy, wind energy, thermoelectric power, and radio f...
