Abstract:
In order to save energy consumption, improve network performance and prolong the life cycle of communication network, a reasonable relay selection algorithm for energy collection wireless sensor networks is proposed. Firstly, taking solar wireless sensor network as an example, the energy consumption and solar energy state of sensor nodes are mathematically analyzed. Then, the cooperation probability is optimized with the interruption probability threshold as the constraint, and the relay nodes participating in the cooperative transmission are controlled to save the energy of cooperative transmission in the system. According to the solar energy status, network energy balance, signal-to-noise ratio and outage probability of the relay node, a multi criteria relay selection strategy is adopted to select the optimal node. Compared with the comparison algorithm, this algorithm can save at least 47.1% power consumption and prolong the network lifetime by 25.9%.
