Gateways and Capacity in Ad Hoc Networks

Abstract

Connectivity with external networks is an essential feature of many ad hoc networks, and such connectivity is enabled by gateway nodes. This paper investigates how the gateways affect the throughput in the ad hoc network. The throughputpsilas dependency on gateway positions, number of gateways and handover properties is sought uncovered by simulations. The results show that the relative positions of gateways in ad hoc networks may have defining impact on the performance of the network. The average path length and the gatewayspsila shared interference coverage are parameters that affect the performance.
