Abstract:
1. A computer-implemented method of simulating performance of a network, wherein the network comprises a plurality of wireless nodes that communicate with each other via a wireless communication channel having a predetermined range, wherein the wireless nodes are modeled based on the their location relative to the range of the wireless communication channel, and wherein the wireless communication channel is modeled based on a bandwidth provided to the wireless nodes that is affected by contention, said computer-implemented method comprising: simulating traffic comprising messages to be transmitted by at least some of the wireless nodes in the network; determining nodes in the network that are reachable by the wireless communication channel; determining a contention measure for the wireless communication channel based on the nodes that are reachable; determining, from a model of the wireless communication channel that is common to the wireless nodes using the wireless communication channel and characterizes throughput in which the wireless nodes using the wireless communication channel are operating as a function of the contention measure, a set of throughput parameters available from the wireless communication channel to the reachable nodes based on the contention measure; and determining a throughput of the simulated traffic provided by the network based on the set of throughput parameters.
