Large-scale ad hoc sensor networks (ASN), when deployed among mobile patients, can provide a dynamic data query architecture to allow the medical specialists to monitor patients at any place. We propose a low-energy, distributed, concentric-zone-based data query mechanism that has the advantages of both proactive and reactive ad hoc routing algorithms to collect medical results from large-scale mobile patients for medical specialists. In order to secure that tree-zone-based ASN, we suggest the using of key-chain to predistribute keys in each sensor. Then we further secure data fusion based on our telemedicine hierarchical architecture. We also propose a scalable global session-key generation mechanism in our tree-zone-based sensor networks.
