this website you offer is release 1.1 ,and this release do not include ZBR(zigbee routing),and these messages in Zheng's website: *** NS2 simulator for 802.15.4 (release v1.1) *** ZigBee routing is now maintained by ZigBee NWK WG and no longer included in this release. >>> Platforms supported ns2 version: 2.26 or above OS: Linux, Sun Solaris and FreeBSD Note: The code has been included in the core release of ns 2.28. I am confusing !
