NS2 Energy Model

在 ns2 中套用有 energy 限制的環境方法如下

使用舊的 trace format 則可以看到

[energy 979.917000 ei 20.074 es 0.000 et 0.003 er 0.006]

這種 trace log

分別代表

energy: total remaining energy
ei: energy consumption in IDLE state
es: energy consumption in SLEEP state
et: energy consumed in transmitting packets
er: energy consumed in receiving packets
