Wireless communication has poised to become one of the most predominant area of research in the field of communication engineering. Wireless Sensor Network also plays a significant role in shaping and linking IoT and communication era. The proposed work considers the two most influential parameters, the power consumption and security, for accessing the performance of Wireless Sensor Network. A novel security algorithm Rabin based Elliptic Curve Cryptosystem ‐ Linear (ECC‐L) has been designed, implemented and compared with existing ECC algorithm. The proposed algorithm uses double binding hash code technique. It supports sensor nodes with bio hash code for identification of authorization network to share the data. The impact of increase in number of nodes to the key performance metrics of WSN like, energy, packet loss, delay, throughput etc., is measured on ECC and proposed ECC‐L by performing simulations. Qualitatively, the metrics show peak performance and significant performance improvement compared to ECC algorithm in terms of reduction in the packet loss, obtaining maximum throughput, avoidance of retransmissions and enhancement of energy efficiency in wireless sensor network. Quantitatively, the simulation results show that the proposed Rabin ECC‐L algorithm perform enhanced better than the existing ECC algorithm for the impact of increase in number of nodes on reduction of control overheads by 21%, reduction in energy consumption by 27%, decrease in packet losses by 13%, increase in throughput by 32% and decrease in average delay by 32%.

In this paper a highly robust and efficient systematic-random linear network coding (S-RLNC) routing scheme is proposed. Unlike classic security systems, the proposed S-RLNC transmission model incorporates an advanced pre-coding and interleaving concept followed by multigeneration mixing (MGM) based data transmission to assure secure and QoS efficient communication. The proposed S-RLNC MGM based routing scheme exhibits higher throughput (99.5-100%) than the existing NCC-ARQ-WSN protocol (80%). Unlike NCC-ARQ-WSN, the proposed model incorporates multiple enhancements, such as RLNC concept, systematic network coding, MGM concept, IBF provision and redundant packet optimization. Combined, all these optimizations have strengthened the proposed S-RLNC MGM to exhibit optimum performance for secure and QoS-centric communication over WSNs.
