An Energy-efficient Secure AODV Protocol in Industrial Sensor Network

As a traditional routing protocol, the Ad hoc Ondemand Distance Vector routing (AODV) protocol has been applied in many industrial sensor network (ISN) fields. Meanwhile, researches on AODV mainly focus on improving performance and enhancing security. Unfortunately, there are a few researches on joint energy efficiency and security. In this article, we proposed an Energy-efficient Secure AODV Protocol (E-SAODV) for industrial sensor network. In E-SAODV, the Low Complexity Verification Mechanism (LCVM) is introduced, and the Delayed Transmitting Mechanism (DTM) is proposed and applied. In LCVM, the polynomial of CRC-4 is introduced to substitutes RSA digital signature in SAODV, in order to guarantee the integrity of data verification, and reduce storage space, computation and energy consumption. The DTM is implemented to separate the checksum and valid data, achieve the tamper-proof. The simulation results demonstrate that comprehensive performance of ESAODV is a trade-off between energy efficiency and security, and with better performance than AODV and SAODV.
