(MANETs) Mobile Ad-hoc Networks is a group of mobile nodes that are connected dynamically, in which each node acts as a router to all other nodes. Due to the absence of centralized administration and dynamic nature, MANETs are vulnerable to various kinds of attacks from malicious nodes. Several secure routing protocols like AODV, DSR, TSR, and OLSR have been used in MANET for transmission of data. In MANET, we are using trust based QoS aware routing protocol for identifying the malicious nodes in the network. Trust is mandatory in routing for transmission of data securely. Hence trust models, trust computation is implemented in the routing protocols. In this paper, survey of several trusts based and QoS aware routing protocol is performed. In this review paper, the study of different trust based and QoS aware AODV protocols that are using trusted infrastructure and trust models is performed for preventing the attacks and misbehavior from malicious nodes in the network. The performance of trust based routing protocol has been analyzed that helps to work efficiently and can be used in various applications of MANETs for improving the security performance of the network.
The Delay Tolerant Network (DTN) is exploited that is an effectual technology without definite incessant linkage in the network in order to provide effectual communication between the devices. In DTNs, numerous conventional routing techniques use the benefit of message replication in order to attain the maximum message delivery rate. However, they experience high communication overhead due to the shortage of effective models to control the message replication. Therefore, this work exploits a trust-based multipath routing protocol to exploit the diverse paths amid source and the destination to alleviate energy restraints. The main intention is to ascertain the optimal path from the whole paths that are present between the sender and destination node. In routing protocol, to enhance security, the metrics such as distance, trust factors are represented as the important modules. On the basis of the metrics, the multipath routing is performed using Particle Swarm Optimization (PSO) -Grey Wolf Optimization (GWO)approach. Subsequent to thereputation and trust-based Context Aware Routing (RCAR) protocol is used to choosethe optimal path with a high trust factor. Moreover, the trust is designed by taking into consideration of trust factors, such as direct, indirect, forwarding rate, history, and availability factors, as well asa utility function. The developed optimization algorithmoutperforms the conventional models with minimum delay, and maximum Packet Delivery Rate (PDR), maximum throughput correspondingly.
