Multihop routing Tinyos
I have a a sensor node that able to send temperature data.
Code:
#include "PacketMsg.h"
module ADC_rawM {
uses interface Boot;
uses interface Leds;
uses interface GeneralIO as Pin1;
uses interface Timer<TMilli> as Timer1;
uses interface Timer<TMilli> as Timer2;
uses interface SplitControl as AMControl;
uses interface Packet;
uses interface AMPacket;
uses interface AMSend;
uses interface Receive;
uses interface Read<uint16_t>;
uses interface Atm128AdcSingle as Adc;
}
implementation {
uint32_t cnt;
uint8_t turn;
uint16_t adc1, adc2, adc3, adc4, adc5, adc6;
uint16_t batt_val;
message_t pkt;
bool busy;
task void SendData() {
PacketMsg* btrpkt = (PacketMsg*)(call Packet.getPayload(&pkt, NULL));
atomic {
btrpkt->nodeid = TOS_NODE_ID;
btrpkt->pktid = ++cnt;
btrpkt->adc1 = adc1;
btrpkt->adc2 = adc2;
btrpkt->adc3 = adc3;
btrpkt->adc4 = adc4;
btrpkt->adc5 = adc5;
btrpkt->adc6 = adc6;
btrpkt->batt_val = batt_val;
}
if(!busy) {
if(call AMSend.send(AM_BROADCAST_ADDR, &pkt, sizeof(PacketMsg)) == SUCCESS) {
busy = TRUE;
}
}
else call Leds.led2Toggle();
}
task void Get_ADC() {
atomic turn++;
call Timer2.startPeriodic(10);
}
event void Boot.booted() {
atomic {
cnt = 0;
turn = 0;
busy = FALSE;
}
call Pin1.makeOutput();
call Pin1.set();
call AMControl.start();
}
event void AMControl.startDone(error_t err) {
if(err==SUCCESS) {
call Timer1.startPeriodic(256);
}
else {
call Leds.led0On();
}
}
event void AMControl.stopDone(error_t err) {
}
event void Timer1.fired() {
call Read.read();
}
event void Timer2.fired() {
atomic {
if(turn==1) call Adc.getData(ATM128_ADC_SNGL_ADC1, ATM128_ADC_VREF_OFF, FALSE, ATM128_ADC_PRESCALE);
if(turn==2) call Adc.getData(ATM128_ADC_SNGL_ADC2, ATM128_ADC_VREF_OFF, FALSE, ATM128_ADC_PRESCALE);
if(turn==3) call Adc.getData(ATM128_ADC_SNGL_ADC3, ATM128_ADC_VREF_OFF, FALSE, ATM128_ADC_PRESCALE);
if(turn==4) call Adc.getData(ATM128_ADC_SNGL_ADC4, ATM128_ADC_VREF_OFF, FALSE, ATM128_ADC_PRESCALE);
if(turn==5) call Adc.getData(ATM128_ADC_SNGL_ADC5, ATM128_ADC_VREF_OFF, FALSE, ATM128_ADC_PRESCALE);
if(turn==6) call Adc.getData(ATM128_ADC_SNGL_ADC6, ATM128_ADC_VREF_OFF, FALSE, ATM128_ADC_PRESCALE);
}
}
event void AMSend.sendDone(message_t* msg, error_t err) {
if(&pkt==msg) {
busy = FALSE;
call Leds.led1Toggle();
}
}
event message_t* Receive.receive(message_t* msg, void* payload, uint8_t len) {
return msg;
}
event void Read.readDone(error_t result, uint16_t data) {
atomic {
if(result==SUCCESS) batt_val = data;
else batt_val = 0;
}
post Get_ADC();
}
async event void Adc.dataReady(uint16_t data, bool precise) {
atomic {
if(turn==1) {
adc1 = data;
post Get_ADC();
}
if(turn==2) {
adc2 = data;
post Get_ADC();
}
if(turn==3) {
adc3 = data;
post Get_ADC();
}
if(turn==4) {
adc4 = data;
post Get_ADC();
}
if(turn==5) {
adc5 = data;
post Get_ADC();
}
if(turn==6) {
adc6 = data;
turn = 0;
post SendData();
}
}
}
}
May I know what code should I add in so that the sensor node able to become the router for another node and at the same time also produce data and send it to the base station? |
