Abstract—The role of the sensor network from simply a means for communication to a technology that can be engineered to improve structural assessment through the interaction of sub-networks fusing data from distributed, heterogeneous sensor arrays. The multi-scale network concept introduced here helps to improve power efficiency, minimize packet loss, latency and eliminate synchronization issues through the use of a decentralized analysis scheme and the activation of sub-networks only in the vicinity of suspected damage. A security mechanism for one layer cannot protect the other layer. Hence cross layer security mechanisms are indeed necessary to protect these large scale multi-hop wireless networks from passive, active and denial of service attacks. In this paper I analyze the performance improvement of multihop routing scalability with the localization support and the consequent risks of a cross-layer approach.
