Packet Drop Attack; mobile ad-hoc network

Sažetak
Mobile ad-hoc network has features like self organization, adaptation in changing environment, nodes in ad hoc network works as router for routing packets. Each nodes have limited resources like bandwidth, battery power and storage capacity. MANETs are vulnerable to Denial of Service (DoS) attacks like black hole attack, gray hole attack and packet drop attack. Packet drop attack is a kind of denial of service (DoS) attack in mobile ad hoc networks. Due to the bandwidth and memory buffer limitation, queue manager of some nodes by default may drop some packets. So differentiating between normal node to attacker node is critical one. In this paper, it is proposed the reputation and trust based mechanism against packet drop attack and improves the network performance interms of throughput, packet drop rate, packet delivery ratio, normalized routing overhead and end-to-end delay.
