Hi I've the algorithm for ETX fo a link to calculate{from the book ,ALGORITHM
AND PROTOCOLS FOR WIRELESs ADHOC NETWORK}
Require: Node X receives an ETX probe packet from Node Y
{ // W = Number of probe packets sent by a node in 1 second }
{ // n xy = number of probe packets heard by Y that was sent by X in the last w
seconds }
{ // n yx = Number of probe packets heard by X that was sent by Y in the last w
seconds }
Extract n xy from the received packet
r xy ←
nxy
wW { // Rating of XY }
Update n y
r yx ←
ny
wW { //Rating of YX }
etx xy ←
1
rxyryx { //ETX for the link XY }
can anybody help me to calculate it in ns2 for routing protocols like aodv and
olsr etc,I"ve postedd the question before ,but no answer.
