AN INTEGRATED SECURED ROUTING APPROACH FOR MANETS Dr. D. CHITRA, DIVYA.K Dr.D. Chitra, Professor, Department of Electronics and Communication engineering Mahendra Engineering College Divya K, PG student, Department of Electronics and Communication Engineering, Mahendra Engineering College ------------------------------------------------------------------------***------------------------------------------------------------------------Abstract This paper aims to integrate different machine learning algorithms to get an optimized and secured routing technique for Mobile Ad-hoc NETworks(MANETs). Routing of packets are highly challenging in MANETs, as they are infrastructure-less networks formed with mobile nodes, connected by flexible wireless links. The main routing challenges in MANETs are the frequent topological changes, limited availability of power resources and vulnerabilities to attacks. This method suggests a technique that is trustworthy that provides fast convergence for topological changes with minimum energy utilization per packet. In this method, a trust-based and energy-efficient fuzzy clustering routing algorithm is used. The Cluster Heads(CHs) are selected depending on the various trust values that provide multi-paths to the destination. Then Bacteria for Aging Optimization Algorithm (BFOA) selects the best path by finding ideal hops to the destination avoiding the misbehaving nodes. The proposed method offers better security, reduced delay and better energy utilization.

The MANETs are formed through the collection of mobile nodes which are connected with wireless links. The topology of MANET changes as the mobile nodes enter and leave the network. When a node along a path leaves the network, the packets along that route must be routed through another alternate path. These frequent topology changes and related routing problems are the major issues in the development of routing protocols for MANETs. The second design issue is related to the power resources availability. The mobile devices depend on one or another form of the exhaustible power source. When the power supply is exhausted at a node, it becomes a dead node and cannot take part in the transmission of the packets. The other problem is the presence of attackers inside and outside the network. In MANETs, there is no centralized monitoring mechanism to detect and prevent intruders. Here, we propose an integrated approach to solve the routing issues in MANETs. This method uses a fuzzy clustering algorithm that determines the CHs through an effective adaptive trust model. As it selects the nodes with maximum trust values and sets the threshold for trust values, the intruder nodes can be easily and effectively identified. It provides multiple paths between the source and destination. In the second stage, an optimal route is selected employing BFOA that uses ideal hops to determine the route.
2. Related works In paper [1], M. Jabirulla and A. Kumar discuss how to plan and analyze obstacles, mobility, and power for optimal MANET routing. It uses a routing protocol framework to uncover viable investigations of obstacles, power, and mobility. The paper aims to solve issues caused by mobility, interface quality, and battery imperative of mobile hubs between overlay associations. The proposed method selects routing choices by deciding the optimal course with energy-productive hubs to keep up network dependability and lifetime. The power mindful utilizations obstacle recognition algorithm for the choice of optimal middle-of-the-road hubs dependent on the available energy level, mobility, and connection quality boundaries. In Mobile Ad Hoc Networks (MANETs), the absence of centralized infrastructure, changes in the network topology, device mobility and data transmission over wireless channels make multi-hop routing a very challenging task. The MANETs can be deployed in many critical applications and developing a routing protocol that deals with these challenges through the design of a Quality of Service (QoS)-assured protocol is a major problem. As the movement of mobile nodes in MANETs occurs frequently, a proper approach with robustness and QoS assurance is required. S. Mostafavi et. al. [2] proposed QMAR-AODV, which is an optimized version of the AODV protocol called the QoS-assured Mobility-Aware Routing protocol. It outperforms E2E-LREEMR and reduces route instability, end-to-end delay, data retransmissions and packet loss while increasing data reception and network throughput, compared to E2E-LREEMR routing protocol. There is a need for a secure protocol for MWSN with mechanisms that take into account the limited resources of the nodes and the dynamism of its nodes’ locations which are included in the research of O. Oladayo and A. Ashraf [3]. Background and Objective Mobile Wireless Sensor Network (MWSN) is a specialized wireless network made up of a large number of mobile sensors, where each sensor is
