[ns] Large ad hoc simulation using FreeSpace propagation model is way too slow

2008-05-17 Thread Ricardo Ulisses
Hi all, I've been doing research on large mobile ad hoc network simulation, so far using Two-Ray Ground radio wave propagation model. I suppose I was achieving a reasonable amount of time to fully complete a simulation run with 10k nodes with 3k connections between them during 300 seconds of

[ns] How I distinguish a packet in queue is a multicast packet?

Hi, all: I'm implementing a multicast-related router-protocol. When a packet enques, I need to determine whether it's a multicast packet. how can I do? Best regards. Yuanzheng, Wang

Hi, u can calculate the total energy consumption this way: when u include the energy model in ns2 u must be supplying some initial energy to each node this multiplied by theno. of nodes gives the total energy supplied to the network. then from the trace file pickup the last trace of each

If you can access the packet header, a packet is a multicast packet if #define MULTICAST_ADDRESS 0xE00 p-daddr() = MULTICAST_ADDRESS Take a look in MAODV code for ns2. It uses this definition in recv() function Sidney Doria 2008/5/17 王远征 [EMAIL PROTECTED]: Hi, all: I'm

Hi Ricardo, the obvious answer - the number of events to process is very different. But why? First of all, the different propagation models result in different transmission ranges. And greater transmission range results in a larger number of nodes receiving an event and hence more processing
