Analysing Degradation Of Network Performance In Manet Due To Presence Of Malicious Nodes
Prolay Ghosh , Dr. Nisarg Gandhewar
Abstract
Mobile Ad hoc Networks (MANET) are networks without a physical infrastructure that offer several wireless hops between nodes. Military and emergency situations, when a permanent infrastructure is not necessary, are where MANET is mostly used in real-time environments. It is a temporary communication infrastructure network for efficient node-to-node communication with few setup requirements. One of the main issues in MANET is security. In a MANET setting, malicious nodes reduce network performance. The mobile ad hoc networks (MANETS) are multi-hop, decentralized networks in which intermediary nodes act as routers to send data packets to their intended locations. Rough set theory is used in this study to identify malicious nodes. The malicious node is located with the aid of the route cache table using the transmission history. Every node in the network keeps track of its neighboring node's transmission history and cache table. Based on measured transmission parameters, such as packet delivery ratio, throughput, end-to-end latency, number of dropped packets, and error rate the node's transmission history is determined. According to the findings of our experiment, the rough setbased strategy boosts network capacity such as packet delivery ratio and reduces end-to-end latency and throughput.
