The link estimate module is used for computing estimations of link quality.
It computes a quality index for links, based on information about how many times a packet has been transmitted, as well as information about incoming packets. The link estimate module exposes an interface that provides functions that are called for incoming and outgoing packets.
| uint16_t collect_link_estimate | ( | struct collect_link_estimate * | le | ) |

| void collect_link_estimate_new | ( | struct collect_link_estimate * | le | ) |
Initialize a new link estimate.
| le | A pointer to a link estimate structure This function initializes a link estimate. |

| void collect_link_estimate_update_rx | ( | struct collect_link_estimate * | le | ) |
Update a link estimate when a packet has been received.
| le | A pointer to a link estimate structure This function updates a link estimate. This function is
called when a packet has been received. The function
uses information from the packet buffer and its
attributes. |
Definition at line 112 of file collect-link-estimate.c.
| void collect_link_estimate_update_tx | ( | struct collect_link_estimate * | le, |
| uint8_t | num_tx | ||
| ) |
Update a link estimate when a packet has been sent.
| le | A pointer to a link estimate structure |
| num_tx | The number of times the packet was transmitted before it was ACKed This function updates a link estimate. This function is
called when a packet has been sent. The function may
use information from the packet buffer and the packet
buffer attributes when computing the link estimate. |

| void collect_link_estimate_update_tx_fail | ( | struct collect_link_estimate * | le, |
| uint8_t | num_tx | ||
| ) |
Update a link estimate when a packet has failed to be sent.
| le | A pointer to a link estimate structure |
| num_tx | The number of times the packet was transmitted before it was given up on. This function updates a link estimate. This function is
called when a packet has been sent. The function may
use information from the packet buffer and the packet
buffer attributes when computing the link estimate. |
