    • The present invention relates to a method for data packet transmissions between a source node and a destination node in a network, the method comprising: -the nodes being configured with an initial sleeping time period duration SP init and an initial wake-up time period duration LP init , -the source node sending a preamble, segmented in micro-preambles, for indicating the beginning of a transmission, the micro-preambles being separated by listening slots, -the destination node sending, upon receipt of at least one of the micro-preamble, a packet indicating its presence, called "Ready-To-Receive", or RTR, packet, and -the source node sending, in response to the RTR packet, a data packet intended for the destination node, wherein the step of sending a preamble comprises: -the source node determining, based on SP init and on LP init , an optimal size of the micro- preambles that minimizes the overall energy consumption in the network for sending and receiving packets related to this preamble transmission.
    • 本发明涉及一种用于网络中的源节点和目的地节点之间的数据分组传输的方法,所述方法包括: - 节点配置有初始睡眠时间段持续时间SPinit和初始唤醒时间段持续时间LPinit - 源节点发送分段在微前同步码中的前导码,用于指示传输的开始,微前同步码由侦听时隙分离,目的节点发送,在接收到微前同步码中的至少一个时 ,指示其存在的分组,称为“就绪接收”,或RTR,分组,以及 - 源节点响应于RTR分组发送旨在用于目的地节点的数据分组,其中发送步骤 前导码包括:源节点基于SPinit和LPinit确定最小化网络中用于发送和接收与该前导码t相关的分组的总能量消耗的最优大小 ransmission。
