Johnson,
I did an implementation of Haar transform joint-encoders using a similar architecture
you have in mind.
I used (for sensor nodes) address 1,2 with 2 (tx->) 1 using its address in the sendmessage command as 1. Then 1 would combine the data with its own &
generate LP & HP coefficients and send them out to the BS via broadcast.
I dont think its much of an issue. Our team is in process of releasing the code.
Cheers
Muthu

Now I know it gives problems... anyway I couldn't do anything because it
takes mi user name from my windows instalation and now I can't change it...
the thing is, what can I do?

In selectParent() function of MultihopLQIM.nc, is the following line a bug?
if (parents[i].cost + parents[i].estimate < newparent) {
Should "newparent" be "parentestimate" ??
=======================
void selectParent() {
int i;
int newparent = m_parent;
uint16_t parentestimate = parents[m_parent].cost +
parents[m_parent].estimate;
// if our parent is invalid, pick the best parent
if (parents[m_parent].addr == MHOP_INVALID_PARENT) {
for (i = 0; i < MHOP_PARENT_SIZE; i++) {
if (parents[i].cost + parents[i].estimate < newparent) {
newparent = i;
parentestimate = parents[i].cost + parents[i].estimate;
}
}
}
// if we have a parent, don't switch unless they're worthwhile
else {
for (i = 0; i < MHOP_PARENT_SIZE; i++) {
if (((uint32_t) parents[i].cost + (uint32_t) parents[i].estimate)
<
((uint32_t) parentestimate) -
(((uint32_t) parentestimate) >> 2)) {
newparent = i;
parentestimate = parents[i].cost + parents[i].estimate;

m_parent = newparent;

About 100us across the network.

No. It is a very simple process to use the GlobalTime interface to
acquire the current time and then set an Alarm or Timer by translating
from GlobalTime to LocalTime and using the t0 and dt parameters of the
Alarm and Timer interfaces.

You are correct, thank you for pointing it out.

Hi
I would like to ask if its possible to do multihop without using broadcasting. For example I have 2 remote motes both responsible for collecting datas and sending it to a base station. Mote 1 can do a direct communciation with the base station while mote 2 needs to relay the data thru mote 1 to reach the base station. How should i go about to do it?
Regards
Johnson

Subject: [Tinyos-help] question on simple_transmit from Rfm_model.c
To: tinyos-help at millennium.berkeley.edu
Message-ID:
Content-Type: text/plain; charset="iso-8859-1"
Hi,
I have a question about the following code from Rfm_model.c. The parameter
bit can be 1 or 0. When simple_trasmit is transmitting bit 1,
transmitting[modeID] is set to 1, meaning it's transmitting. However, when
simple_transmit is transmitting bit 0, transmitting[modeID] is set to 0,
meaning it's not transmitting (actually it's transmitting bit 0). Why is it
so? I must have the concept wrong. Could any help me on this?
void simple_transmit(int moteID, char bit) {
int i;
transmitting[moteID] = bit;
for (i = 0; i < tos_state.num_nodes; i++) {
radio_active[i] += bit;
}
}
Regards,
Haibin

There is a link failure on the http://www.moteiv.com/community/Boomerang_UART0_Sample page. I can´t download the Moteiv Boomerang Uart0 Sample.tar.gz. I think I can use the UART as a simple debuger. Does anyone used the UART as a trace?
