WIRELESS COMMUNICATION NETWORKS Modeling and Simulation
2
Scale A common Issue How accurate do you need? What are you trying to understand? What are your assumptions?
3
Scale Examples Experiments to understand connection dynamics in a cell phone network Mobility is important Connection info is important What might be left out Cell hardware? Routing algorithms? Voice only (no data)? MAC protocol transients
4
Scale Examples Experiments to discover effect of transience in BGP in high- tier internet traffic DES may not even be sufficient! Need fine-granularity Still may not need MAC protocols!
5
Scale Mobile Ad Hoc Wireless How many nodes? How fast do they move? How complex of a wireless model? Simple SNR, Directed Antenae, co-channel interference… Battery life?
6
By the way Discrete Event Simulation! A simple concept Agents and Events Very Intuitive Very OO friendly, Hooray! What package to use? Look at scale issues! How much do you like to program?
7
Further Resources Read! Best way by far to understand the state of the art is to read papers Keep a close eye on the models they use… Lots of work in MAC and wireless channel-space sharing NS3 Abundance of general DES
