Functions | |
void | collect_link_estimate_new (struct collect_link_estimate *le) |
Initialize a new link estimate. | |
void | collect_link_estimate_update_tx (struct collect_link_estimate *le, uint8_t tx) |
Update a link estimate when a packet has been sent. | |
void | collect_link_estimate_update_tx_fail (struct collect_link_estimate *le, uint8_t tx) |
Update a link estimate when a packet has failed to be sent. | |
void | collect_link_estimate_update_rx (struct collect_link_estimate *n) |
Update a link estimate when a packet has been received. | |
uint16_t | collect_link_estimate (struct collect_link_estimate *le) |
Compute the link estimate metric for a link estimate. |
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 | ) |
Compute the link estimate metric for a link estimate.
le | A pointer to a link estimate structure |
Definition at line 109 of file collect-link-estimate.c.
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.
Definition at line 64 of file collect-link-estimate.c.
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 103 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.
