A new architecture for heterogeneous context based routing

Abstract

This paper presents a new architecture for a heterogeneous context based routing system called HCBR that classifies devices with homogeneous network interfaces into horizontal cells and uses devices with interfaces in different cells to combine these cells to a heterogeneous ensemble by using vertical communication structures. Furthermore, a central and a decentral approach of this HCBR architecture are described which allow a flexible device communication inside an ensemble and permit reliable and context based data exchange between devices of different cells. Additionally, requirements in Quality of Service (QoS) as well as context of applications are considered for selection of suitable horizontal and vertical communication channels in a highly heterogeneous network infrastructure of a pervasive environment. © 2008 Springer-Verlag.
