DETECTION OF MISBEHAVING NODE USING SECURE-ACK IN MANET

Modules: 1. Network Structure Creation: This module will enable the user to view the network structure created using the simulation environment and the location of nodes along with the nomenclature of sender and receiver mechanism. 2. Data Transmission Simulation: This module will facilitate the user to analyze the data transmission occurring between the sender and receiver. 3. Simulation Scenario for ACK packets: In this mechanism, the existing acknowledgement procedure consisting of direct acknowledgement from destination to source will be facilitated here wherein if no acknowledge 4. Simulation Scenario for S-ACK packets: In this mechanism, the three consecutive nodes (i.e., F1, F2, and F3) work in a group to detect misbehaving nodes in the network. Node F1 first sends out S-ACK data packet Psad1 to node F2. Then, node F2 forwards this packet to node F3. When node F3 receives Psad1, as it is the third node in this three-node group, node F3 is required to send back an S-ACK acknowledgment packet Psak1 to node F2. Node F2 forwards Psak1 back to node F1. If node F1 does not receive this acknowledgment packet within a predefined time period, both nodes F2 and F3 are reported as malicious. 5. MRA: Misbehavior report authentication part implementation (detailed descry. In paper) 6. Comparative Analysis in terms of Throughput and Packet Delivery Ratio: In this module, the user will be able to view the throughput generated and packet delivery ratio analyzed in graphical format to identify the behavior of network in case of the above scenarios.
