ns3wimax.py - This script demonstrates using CORE with the ns-3 Wimax model.
|
|
*** Note that this script is not currently functional, see notes below. ***
|
|
Current issues:
|
|
- large amount of base station chatter; huge trace files, 70% CPU usage
|
|
- PCAP files unreadable
|
|
- base station causes segfault if it sends packet; due to missing service flows
|
|
(but AddFlow() is not available for bs devices)
|
|
- no packets are sent between nodes - no connection?
|
