Trust-Based Malicious Node Detection and Routing in Wireless Sensor Networks

Wireless Sensor Networks (WSN) have arisen as a significant innovative area in wireless
technology. In the nearby future, WSN are projected to comprise of thousands of sensor nodes, each
having sensing proficiency with restricted energy, computational and communication power. In the
previous work, Hierarchical Energy-Balancing Multipath routing protocol for Wireless Sensor Networks
(HEBM) is introduced to improve the energy consumption and network lifetime. However it does not
consider the security of the sensor network. To solve this problem the proposed system introduced a
Trust-based Malicious node Detection and Routing (TMDR) approach. Based on the trust calculation the
malicious nodes are detected and eliminated from the network. Then an optimal cluster head is selected
based on the node weight, remaining energy and distance between sensor nodes and base station. Finally
Time Division Multiple Access (TDMA) schedule allocate the time to each cluster member for packet
transmission. The experimental results show that the proposed system achieves high throughput, energy
consumption and packet delivery ratio.
