EMRCS: Efficient Multipath Routing based Cryptography Scheme in Wireless Sensor Networks

In Wireless Sensor Networks, Sensor nodes are controlled by either base station or without bases station. In our scheme, the sensor nodes do not depend on the base station. Once the sensor node sent a packet to the destination node, the residual energy is calculated through the multipath routing approach. There is a need of Secure and Energy based Routing in the wireless sensor network. This requirement may lead to a number of routing protocols which effectively use the limited resources available at the sensor nodes. Many routing protocols will attempt to find the efficient and secure multipath routing. In order to determine the secure and energy efficient routing, we proposed the Efficient Multipath Routing based Cryptography Scheme (EMRCS) which guard against the ciphertext attacks and all known attacks. In the first phase, we proposed multipath routing to improve the minimal energy consumption and network lifetime. In second phase, we used the concept of Elliptic Curve Integrated Encryption and Decryption Scheme to reduce the effect of attacks. In third phase, the energy consumption model is proposed. By simulation results, the proposed EMRCS achieves better delivery ratio, throughput, less delay and energy consumption in terms of mobility, time and number of nodes than the existing scheme SBYaoGG, AFTMR and NMRA.
