Secure Healthcare Data Aggregation Scheme for Internet of Things

Internet of things (IoT) involves massive number of smart devices that can communicate across different networks to exchange data. IoT enabled smart healthcare data is aggregated for transmitting to FoG server. Healthcare data is sensitive in nature, so there is a need to provide protection against various security attacks. This paper presents a secure healthcare based data aggregation (SHDA) scheme to transmit sensitive data from sensor nodes to collector nodes that further transmit to the FoG node. It includes a proposed model for data collection from sensing devices and aggregate at collector nodes. Next, we present the message receiving algorithm at collector node and message extraction algorithm at FoG node. SHDA is simulated using NS2.35 in Fedora Core 16 where TCL is used for node deployment and C language is used for message handling among devices. AWK script are used to get the results of simulations from trace files. Results prove the dominance of our scheme as compared to counterparts in terms of communication cost, computation cost and energy consumption.
