Abstract: As the energy harvesting wireless sensor networks(EH-WSNs) can work forever,they have a lot of promising applications.The available one-hop multicast schemes of EH-WSNs have the shortcomings that they have not taken the feature of dynamic link quality into account and waste the energy due to the overflow of energy storage,ect.This paper presented one energy-efficient one-hop multicast scheme with high packet delivery rate.This scheme integrates the erasure code and considers the node energy,energy harvesting rate and current link quality to analyze the expected number of correctly received packets of the follow data block.This scheme only let the sensor receive the block whose expected number of correctly received packets is greater than or equal to one threshold and the block followed by the occurrence of energy overflow once the sensor does not receive it,effectively reducing the occurrence probabilities of energy overflow and the failure decoding due to non-perfect link quality.Simulation results demonstrate that,compared to the available scheme,the proposed scheme is able to greatly improve the one-hop multicast packet delivery rate of EH-WSNs.
