Trust and privacy based vertical handoff decision algorithm for telecardiology application in heterogeneous wireless networks.

Telecardiology is one of the emerging fields of telemedicine to improve the cardiac patient's life quality. It uses the information and communication technologies to monitor the cardiac patients by healthcare professionals at distant. The telecardiology system demands for ubiquitous connection to assure promising services. Such a seamless service is provided by heterogeneous wireless technology. But the open network infrastructure of the heterogeneous networks is prone to various security attacks which makes patient privacy susceptible. Therefore, in this paper, the telecardiology system incorporated with Trust and Privacy based Multi-attribute Vertical Handoff decision algorithm towards decide on an best possible association amongst the available alternative candidates based on the patient health condition. Simulation results show enhancement in provisions of handoff rate, reduced blocking probability and improved performance throughput. [ABSTRACT FROM AUTHOR]
