Energy efficient transmission in a network
First Claim
1. A method for data packet transmissions between a source node and a destination node in a network, the method comprising:
- configuring the nodes with an initial sleeping time period duration SPinit and an initial wake-up time period duration LPinit,sending, by the source node, a preamble, segmented in micro-preambles, for indicating the beginning of a transmission, the micro-preambles being separated by listening slots,sending, by the destination node, upon receipt of at least one of the micro-preamble, a packet indicating its presence, called “
Ready-To-Receive”
, or RTR, packet, andsending, by the source node, in response to the RTR packet, a data packet intended for the destination node,wherein the sending of the preamble comprises;
determining, by the source node, based on said SPinit and on said LPinit, an optimal size of the preamble as segmented into the micro-preambles that minimizes the overall energy consumption in the network for sending and receiving packets related to this preamble transmission, andwherein the method further comprises;
determining for the source node, before transmitting the micro-preambles, a random size offset and modifying the size of the micro-preambles by applying the offset to the optimal value.

Abstract
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 SPinit and an initial wake-up time period duration LPinit, —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 SPinit and on LPinit, 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.

-
configuring the nodes with an initial sleeping time period duration SPinit and an initial wake-up time period duration LPinit, sending, by the source node, a preamble, segmented in micro-preambles, for indicating the beginning of a transmission, the micro-preambles being separated by listening slots, sending, by the destination node, upon receipt of at least one of the micro-preamble, a packet indicating its presence, called “
