A Secured and Energy Efficient Wireless Sensor Networks (WSN) Utilizing CRT- Based Forwarding Technique

摘要

Purpose:The purpose of this research is to design power efficient and secured WSNs. Design/Methodology/Approach:A Chinese Remainder Theorem (CRT) was used to design a secured and energy efficient network as well as a forwarding algorithm. The algorithm breaks down the information that is received by each hub in order to diminish the number of bits transmitted by each sending hub in the system. The design implements Local Closet First (LCF) to determine the best destination in order to send the message to the next hop. Simulations were used to assess the execution of the hubs. The simulations were performed on Prowler (Probabilistic Wireless Network Simulator) running under MATLAB. Findings:Vitality and reliability are the most obliging elements on the usefulness of WSNs. The results acquired demonstrates that the proposed scheme outperforms traditional methodologies as far as vitality sparing (because nodes only need to send small packets to the sink), dependability, straightforwardness and reasonable circulation of vitality utilization among all hubs in the system and in addition decrease in delay of the sent data. Also message security is enhanced because the remainders of sensed data are sent instead of data itself. The received packet is encrypted and to decrypt the message, the receiving nodes should have the moduli set which serves as the secret key.Research limitations/implications: In this research work, application level quality of service (Qos) constraints is not met. Error detection and correction is also not considered.Originality/Value: The proposed wireless sensor networks design is one of the few designs if not the only design that addresses the integration of energy reduction and secured WSNs using CRT packet splitting algorithm with local closet first (LCF).
