Error when the OnOffAplication datarate is increased [WiMAX]

Created attachment 1699 [details] Simulation script of wimax network Simulating a WiMAX network with several SS, results seem be ok if you choose a low datarate in the OnOffAplication (such as 128kbps). However, if you choose a higher value, (ej: 1280kbps) the simulator crashes like: assert failed. cond="m_buffer.GetSize () >= start + length", file=../src/network/model/packet.cc, line=232 terminate called without an active exception The attached script works fine with the 128kbps value, but crashes with the value 1280kbps, without change anything more. Seems like a bug. Any idea?
This is in Packet::CreateFragment
Due to the impossibility to work with the WiMAX module I have applied a patch which allows increase the throughput without this error. The problem was in the fragmentation procedure, so I have disabled it. For this reason is not really a "patch", since do not fix anything but avoid it. Aditionally corrects mistakes in time units in wimax/model/simple-ofdm-wimax-phy.cc I upload it in case anyone is interested.
