Function Documentation

◆ trickle_callback()

void trickle_callback ( trickle_t * trickle )

is called after the interval is over and executes callback function

Parameters

[in] trickle trickle timer

◆ trickle_increment_counter()

void trickle_increment_counter ( trickle_t * trickle )

increments the counter by one

Parameters

[in] trickle trickle timer

◆ trickle_interval()

void trickle_interval ( trickle_t * trickle )

is called after the interval is over and calculates the next interval

Precondition: (trickle->I > 0) required for trickle algorithm to work

Parameters

[in] trickle trickle timer

◆ trickle_reset_timer()

void trickle_reset_timer ( trickle_t * trickle )

resets the trickle timer

Precondition: trickle->I > trickle->Imin

See also: https://tools.ietf.org/html/rfc6206#section-4.2, number 6

Parameters

[in] trickle the trickle timer

◆ trickle_start()

void trickle_start	(	kernel_pid_t	pid,
		trickle_t *	trickle,
		uint16_t	msg_type,
		uint32_t	Imin,
		uint8_t	Imax,
		uint8_t	k
	)

start the trickle timer

Precondition: Imin > 0; (Imin << Imax) < (UINT32_MAX / 2) to avoid overflow of uint32_t

Parameters

[in]	pid	target thread
[in]	trickle	trickle timer
[in]	msg_type	msg_t.type for messages
[in]	Imin	minimum interval in ms
[in]	Imax	maximum interval in ms
[in]	k	redundancy constant

◆ trickle_stop()

void trickle_stop ( trickle_t * trickle )

stops the trickle timer

Parameters

[in] trickle trickle timer
