Hello I have to simulate TCP over UMTS. My topology consists of only two base stations and 100 mobile terminals. My difficulties are: MAC : I want to use CDMA for the MAC type. There doesn't seem to be an object for it yet. Now this is for a WAN so I can't really use 805.11. On the other hand, TCP doesn't care what lies bellow it as long as it gets the packet. Do you think it matters? Routing:- The only routing i want to implement will at the base Stations(BS) since mobile phone nodes do not communicate directly to each other.Can I get away with this? Traffic generation: Is there any program I can use to generate random traffic between the mobile terminals and the BS.Those available in the ns down load generate traffic between mobile nodes. Hand off: Is it possible to implement the handoff object in the satellite module into this? Edward |
