GSA: An Architecture for Optimising Gateway Selection in Dynamic Routing Groups

Inhalt:
The proliferation of the increasing number of devices and technologies has brought about the extension of the concept of roaming users to roaming networks. This has inspired many researchers to investigate optimal mechanisms to enable communications for such roaming networks. Within the European 6th Framework Ambient Networks Project, we identify such roaming networks as dynamic Routing Groups, which consist of a number of different types of nodes with different capabilities. External communications from nodes within the routing group can be done via selected Gateway nodes. In this paper we present the Gateway Selection Architecture (GSA) which provides support for Gateway identification, management and selection for nodes within a RG. We describe the benefits of this architecture and compare it to other known approaches.
