Trust Aware Secured Data Transmission Based Routing Strategy Using Optimal Ch Selection in Mobile Ad-Hoc Network

In Mobile Ad-hoc Network (MANET), the secured means of transferring data over malicious nodes is being considered as a significant aspect. The assurance of trust among the MANET nodes are regarded as an important constraint in providing higher security dynamic network topology deviation & the open wireless constrictions. However, nodes malicious actions decrease the trust level of nodes which may leads to insecure delivery of data. The malicious attacks rise leads to excessive consumption of energy in a network which thereby affects lifetime of network. The nodes should update their positional information which is lacking in traditional methods and it may lead to lowering the level of trust among nodes. Therefore, trust rate computation using mobility models & energy is essential which too needs their update for the secured delivery of data. In this work, a trust-aware ad-hoc route discovery protocol is presented for enhancing trust level among MANET nodes. The neighbor node is estimated using RSSI and the neighbor log collection is carried by means of packet id sequence extraction on trust rate estimation. Then, the optimal selection of cluster head is carried by using multi-faceted cuckoo search optimization approach. The trusted path is estimated by computing trust rate which recognizes the trusted path and discovers better routing path for the secured means of data transmission. Finally, the data is transmitted over trusted and secured path. The performance is estimated for the measures like throughput, routing overhead (RO), packet delivery ratio (PDR), End-to-End delay, & average consumption of energy.
