Adaptive Approaches of Relieving Broadcast Storms Connecting MANET to Internet
Bo Li · Jisuanji gongcheng · 2006
Mobile Ad Hoc networks are extremely flexible,self-configurable and easy-to-deploy wireless networks.The biggest challenge to connect mobile Ad Hoc networks to the Internet stems from the need to inform ad hoc nodes about available gateways in an extremely changing scenario while making a reasonable consumption of the scarce network resources.This paper proposes and simulates a new adaptive Internetworking scheme that not only can adjust the scope of the gateway advertisement packets dynamically,but also can relieve broadcasting storms of flooding gateway advertisement packets with counter-based scheme.Simulation results with NS2 show that the approach can adapt to the change of mobile ad hoc networks’ scale and node density well and can achieve good connectivity while keeping overhead costs low.
