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;
}
