We are the team of developers from System Platforms Research Labs., NEC Corporation.
At this time, we added an implementation of WLAN power save functions to ns-2.33. We would like you to look at our changes and give us your opinion about them. A patch file and a patched package for power save functions are avalable at http://nspme.sourceforge.net/. Best regards. Yoshinori Miyamoto, Makoto Fujinami, Takuya Murakami
