Secured System Against DDoS Attack in Mobile Adhoc Network
The risks to users of wireless technology have increased as the service has become more popular. Due to the dynamically changing topology, open environment and lack of centralized security infrastructure, a Mobile Ad hoc NETwork (MANET) is vulnerable to the presence of malicious nodes and to ad hoc routing attacks. There are a wide variety of routing attacks that target the weakness of MANETs. This paper focuses on mobile ad hoc network's routing vulnerability and analyzes the network performance under two types of attacks, flooding attack and black hole attack that can easily be employed against the MANETS.
