Hi, I have read that two paper however that was exactly what I have said in my previous email, the paper mean nothing if you do not show how you implement it and how you measure it. The 2 paper said they have done something, but how they did it, does they do the right way? There are no explanation and public work (code, analysis script, validation ...) after they public their paper and therefore they can not guanranty that the result is correct (it could be 1+1 =3). I'm finding a resource that give a hint of how to extract the metric regarding energy consumtion in wireless network from new trace format. There are not much information about is so far. Please share it or post here if you know how to locate it from somewhere or someone. Thank you.

Everything going further is implementation and protocol specific. If you want some hints and an example implementation take a look at the wpan folder for the zigbee protocol. The university washington had also made some improvements - google for washington university zigbee... The thing to do is in general simple and straight forward: get the time spent in different states, like sending, receiving, idle, sleeping(...) and hand them over to the energymodel with the corresponding energyconsumption. The problem is to find each of the values and the right parts of the code to insert the statements... I don't know any papers that explain the implementation for ns2, only some with specific sleep models or sleep schedulings for specific protocols... But if you receive some useful answers it would be very kind, if you'd forward them to me :) Greets, Matthias pipi VN schrieb: > I'm studying about the energy saving strategies in wireless network.
