Optimal Utilization of Dynamic Hop-Aware Buffer Management Scheme for Manet

Abstract

The wireless ad hoc network, the mobile ad hoc network is one of the most popular network technologies in research and development. The network's ad-hoc nature kept attracting researchers and engineers to find new and improved techniques. This article presents an analysis of ad hoc network and buffer management technology for mobile devices. We propose a dynamic Hop Aware Buffering (DHAB) scheme to reduce packet losses and delays in MANETs. In this scheme, the buffer is virtually partitioned based on the number of hops passed and the significance of the packet. This article examines resource depletion attacks on the LQSR protocol layer, which disable networks by rapidly degrading the node's battery power. These vampire attacks are not specific to a particular protocol, but depend on the characteristics of many known protocol classes. We find that all the logs under investigation are affected by vampire attacks that are destroyed, difficult to detect, and easy to execute if only a malicious insider sends only protocol-compliant messages. In the worst case, a single vampire can increase network-wide power consumption by a factor of O (N), where N equals the number of network nodes. The methods we discuss to mitigate these types of attacks include a new proof-of-concept protocol that limits the damage caused by vampires during packet forwarding. In addition, the size of the virtual partitions changes dynamically depending on the usage and security threshold of the partition.
