As the matter of fact, our experienced technical professionals are well qualified and ready to provide appropriate guidance in Cooja. Without any delay, let’s see the utilization of collect view in Cooja over this article.
The collect view code in Cooja is performed through the simulation code which is highlighted in following.
void
collect_view_construct_message(struct collect_view_data_msg *msg,
const linkaddr_t *parent,
uint16_t parent_etx,
uint16_t current_rtmetric,
uint16_t num_neighbors,
uint16_t beacon_interval)
{
static unsigned long last_cpu, last_lpm,
last_transmit, last_listen;
unsigned long cpu, lpm, transmit, listen;
msg->len = sizeof(struct collect_view_data_msg) / sizeof(uint16_t);
msg->clock = clock_time();
#if TIMESYNCH_CONF_ENABLED
msg->timesynch_time = timesynch_time();
#else /* TIMESYNCH_CONF_ENABLED */
msg->timesynch_time = 0;
#endif /* TIMESYNCH_CONF_ENABLED */
energest_flush();
cpu = energest_type_time(ENERGEST_TYPE_CPU) – last_cpu;
lpm = energest_type_time(ENERGEST_TYPE_LPM) – last_lpm;
transmit = energest_type_time(ENERGEST_TYPE_TRANSMIT) – last_transmit;
listen = energest_type_time(ENERGEST_TYPE_LISTEN) – last_listen;
/* Make sure that the values are within 16 bits. If they are larger,
we scale them down to fit into 16 bits. */
while(cpu >= 65536ul || lpm >= 65536ul ||
transmit >= 65536ul || listen >= 65536ul) {
cpu /= 2;
lpm /= 2;
transmit /= 2;
listen /= 2;
}
msg->cpu = cpu;
msg->lpm = lpm;
msg->transmit = transmit;
msg->listen = listen;
last_cpu = energest_type_time(ENERGEST_TYPE_CPU);
last_lpm = energest_type_time(ENERGEST_TYPE_LPM);
last_transmit = energest_type_time(ENERGEST_TYPE_TRANSMIT);
last_listen = energest_type_time(ENERGEST_TYPE_LISTEN);
memcpy(&msg->parent, &parent->u8[LINKADDR_SIZE – 2], 2);
msg->parent_etx = parent_etx;
msg->current_rtmetric = current_rtmetric;
msg->num_neighbors = num_neighbors;
msg->beacon_interval = beacon_interval;
memset(msg->sensors, 0, sizeof(msg->sensors));
collect_view_arch_read_sensors(msg);
}
Following that, we have implemented the collect view in Cooja through opening the configuration file and starting the simulation process in simulation window and the result is shown in the following image.
