Purpose Security of wireless body area network communication is highly important as it directly impacts human life. This paper aims to focus on battlefield application area of WBAN for implementing security where data must be protected against various possible attacks before delivering over a public network. Design/methodology/approach Providing a strong security system is still a research challenge due to low computational power of used sensors for protecting transmission data. In this paper, the authors have proposed an optimized security solution for multithreaded wireless body area network (MWBAN) using trust-based distributed group key management technique to overcome the drawbacks of existing elliptical curve cryptography-homomorphism (ECC-Homomorphism) scheme as well as coded cooperative data exchange group key management (CCDE_GKM) scheme. Findings The proposed optimized security solution is implemented for a particular deployment strategy and test runs are conducted. It is found that when number of attack nodes increased to 25, compared to ECC–Homomorphism and CCDE_GKM for the proposed trust-based distributed group key management technique there is an improvement in performance parameters such as throughput is dropped to only 10.11 Kbps, average delay is just 3.4 s, energy consumption is maximum 29 joules, packet loss is only 12.3 per cent, 90.9 per cent truly can detect attack, only 8.9 per cent false attack detection and 84 per cent true negative detection. Social implications Medical care can be provided to human beings with much ease and flexibility via remote monitoring. The user can be at any place, can do his/her everyday work while remotely being monitored of their health parameters and secured transmission of their data to the health-care center for medical service in need. Originality/value This paper presents an optimized security solution for MWBAN using trust-based distributed group key management technique where bilinear pairing theory is used as major cryptographic base. Optimal key is selected based on trust value and also attack nodes are detected based on trust value to control participation in communication.

Background and objective: In the Wireless Body Area Network (WBAN) sensors are placed on the human body; which has various mobility patterns like seating, walking, standing and running. This mobility typically assisted with hand and leg movements on which most of the sensors are mounted. Previous studies were largely focused on simulations of WBAN mobility without focusing much on hand and leg movements. Thus for realistic studies on performance of the WBAN, it is important to consider hand and leg movements. Thus, an objective of this paper is to investigate an effect of the mobility patterns with hand movements on the throughput of the WBAN. Method: The IEEE 802.15.6 requirements are considered for WBAN design. The WBAN with star topology is used to connect three sensors and a hub. Three types of mobility viz. standing, walking and running with backward and forward hand movements is designed for simulation purpose. The throughput analysis is carried out with the three sets of simulations with standing, walking and running conditions with the speed of 0 m/s, 0.5 m/s and 3 m/s respectively. The data rate was increased from 250 Kb to 10000 Kb with AODV protocol. It is intended to investigate the effect of the hand movements and the mobility conditions on the throughput. Simulation results are analyzed with the aid of descriptive statistics. A comparative analysis between the simulated model and a mathematical model is also introduced to get more insight into the data. Results: Simulation studies showed that as the data rate is increased, throughput is also increased for all mobility conditions however, this increasing trend was discontinuous. In the standing (static) position, the throughput is found to be higher than mobility (dynamic) condition. It is found that, the throughput is better in the running condition than the walking condition. Average values of the throughput in case of the standing condition were more than that of the dynamic conditions. To validate these results, a mathematical model is created. In the mathematical model, a same trend is observed. Conclusion: Overall, it is concluded that the throughput is decreased due to mobility of the WBAN. It is understood that mathematical models have given more insight into the simulation data and confirmed the negative effect of the mobility conditions on throughput. In the future, it is proposed to investigate effect of interference on the designed network and compare the results.
