Artificial Immune System Based Problematic Node Identification in Mobile Ad Hoc Network

Abstract

Mobile Ad hoc Networks (MANET) are characterized by the absence of any centralized newlinecontrol system as well as any structured infrastructure. The nodes have greater newlineflexibility to join and leave the network. This makes the network and its topology more newlinedynamic. The dynamic topology of a MANET creates numerous difficulties which are newlinefurther complicated by the decentralized framework wherein every node can go about newlineas a host, a router and a relay for traffic. The dynamism in topology causes frequent newlinetraffic and routing changes. These changes in routing can lead to, significant packet, newlineand challenged fault detection and correction. Further, heavy churning in MANET makes newlinethe network highly susceptible to various types of attacks. Hence, securing MANET is newlinea difficult and challenging task. Solutions based on Human Immune System (HIS) are newlineone of the popular areas of research to make the network secured. newline
