Flow transfer times in wireless multihop ad hoc networks

A flow level model for multihop wireless ad hoc networks is presented in this paper. Using a flow level view, we show the main properties and modeling challenges for ad hoc networks. Considering different scenarios, a multihop WLAN and a serial network with a TCP-like flow control protocol, we investigate how capacity is allocated between the users of a network. This leads to two different Processor Sharing models, BPS and DPS, which are discussed and compared. Simulation is used to validate the proposed models. The flow level view leads to new insights into the capacity of ad hoc networks, opening new opportunities for analyzing this type of network
