A Network Reliability Based Secure Routing Protocol (NRSRP) for Secure Transmission in Wireless Body Area Network

Wireless Body Area Networks (WBAN), a sub type of Wireless Sensor Networks is mainly used in the health care sector for applications like remote patient monitoring, entertainment, gaming and sports fitness etc. It is a collection of short distances wireless sensor nodes with little processing capabilities. The tiny sensor component connects with the central coordinator for data aggregation or calculation while keeping track of health indicators like body temperature, ECG, Pulse rate, EMG, MEMS pressure sensor, etc. Through the internet or cloud service providers, the stored data is transmitted to distant monitoring equipment. Energy usage, secure network connection, and the potential for assaults carried out by hostile nodes that cause issues for the network are the biggest challenges for this technology. The proposed Network Reliability based Secure Routing Algorithm (NRSRA) first determines the secure path based on the distance, hops, and travel time between sources and destinations then it checks the data which sent by the sensor nodes. The authentication algorithm used in the second phase to provide authentication for the nodes. By applying these two proposed algorithms for communication, it is proved through experiments that the proposed secure routing algorithm and the outlier’s detection algorithm are able to perform security and provides reliability in the network. Moreover, these two algorithms provide improved quality of service with respect to the Network Assumption, Trust Computation, Data Trust and Data Aging i.e. unlike a security method. This proposed work has been implemented in NS3 Simulator.
