Wireless sensor networks (WSN) is self-organizing network that has numerous tiny sensor nodes used to track and monitor applications in an extensive range. However, security and energy consumption are considered two important issues, because of the open medium and restricted energy resources. In this paper, the multiobjective-trust centric reptile search algorithm (M-TCRSA) is proposed to perform the secure cluster based routing for WSN. The M-TCRSA is used to ensure the secure cluster head (SCH) and secure route discovery to achieve reliable communication over the WSN. Hence, the developed M-TCRSA method provides improved security against malicious attacks while enhancing energy efficiency. The main objective of the M-TCRSA is to achieve secure data transmission while increasing the life expectancy of the WSN. The performance of M-TCRSA is analyzed by means of packet delivery ratio (PDR), throughput, end to end delay (EED), jitter and life expectancy. The existing research such as trust-based routing using adaptive genetic algorithm (TAGA), trusted cluster based energy and lifetime aware routing (TCELR), secure clustering and routing using IMFO (SCRIMFO) and cost centric cuckoo search algorithm (CCCSA) are compared with the M-TCRSA. The PDR of the M-TCRSA is 99.27% for 400 nodes which is high when compared to the TAGA, TCELR, SCRIMFO and CCCSA.
