Grid networks aim to build a future architecture for efficient resource sharing and distributed service provisioning in a multi-provider environment. However, mobility, QoS support, and commercial service provisioning -all essential issues in future networks -pose new challenges to grid networks, both from a technical and economic point of view. Therefore, the Akogrimo project aims at developing an integrated service architecture for commercial mobile grid networks. This paper presents the Akogrimo architecture and its key characteristics, integrating mobility and network layer QoS support in a commercial grid environment.
