Reliable Transfer of Ownership for Estranged Devices

Body sensor networks (BSN) sometimes involve a dynamic and flexible membership of its sensors especially when monitoring of massive users in a disaster scenario. The problem of estranged devices requires a transfer of ownership from one BSN to a different BSN. Based on the models, a BSN has to adapt different mechanisms to address possible threats caused by estranged devices. The objective of our work is to illustrate this problem in detail and demonstrate how we can exploit dynamic context data collected in a BSN (worn by a patient) to solve the estranged-device problem. We propose an experiment to show how a BSN can infer the ownership of a body sensor node.
