A Novel Architecture for Provisioning Basic Services in Heterogeneous Pervasive Environments

The paper proposes a novel improvised architecture for providing fundamental services through exploitation of node heterogeneity so that relatively stable and capable devices cooperate and assist resource-poor devices. The novel hierarchical architecture called NeVo (Network of Volunteers) uses a small subset of the volunteer nodes to perform basic services such as QoS provisioning, service discovery, mobility management, and trust management in pervasive environments. Service discovery protocols and trust management schemes that utilize the NeVo architecture are presented. The utility of NeVo as a flexible and adaptable architecture for creating and provisioning fundamental services is validated through extensive simulation studies.
