Executive Summary

Many anticipate a future wireless world filled by a multitude of user devices and wireless technologies. Effective management of this kind of heterogeneous, mobile, and rapidly changing ad hoc networks will be a challenging task. The authors present and evaluate the Ambient Networks Gateway Selection Architecture (GSA), which provides support for gateway discovery, management, and selection for mobile nodes within dynamic routing groups. A Routing Group (RG) is a cluster of nodes in physical proximity, aware of the group membership, with a common goal of optimizing mobility management and routing functionality in the group. A gateway is a mobile node that provides packet relaying and connectivity services to other nodes in the RG.
