Secure and Proficient Cross Layer (SPCL) QoS Framework for Mobile Ad-hoc

Abstract

A cross layer QoS framework is a complete system that provides required QoS services to each node present in the network. All components within it cooperate together for providing the required services. In existing QoS frameworks there is no security mechanism provided while Security is a critical aspect for QoS in the MANET environment. Cross layer QoS framework tend to be vulnerable to a number of threats and attacks like, over/under-reporting of available bandwidth, over-reservation, state table starvation, QoS degradation, information disclosure, theft of services timing attack, flooding attack, replay attack, and denial of service (DoS) attack, attacks on information in transit and attacks against routing. So it is necessary when designing protocols for QoS framework, the harmony between security and QoS must be present as one impacts the others. In this work we proposed secure and proficient cross layer (SPCL) QoS frameworks which prevents from various types of threats and attacks. The proposed SPCL QoS framework achieves better performance compared to existing QoS frameworks in metrics of throughput, packet drop ratio, end-to-end delay, and average jitter in both condition when malicious node present in the network and when malicious node not present in the network

Quality of Service-Aware Security Framework for Mobile Ad Hoc Networks using Optimized Link State Routing Protocol

“…Sahu et. al [7] proposed a cross-layer security framework that prevents malicious attacks in the network. The proposed framework used throughput, end to end delay, jitter, and packet drop ratio as QoS metrics where-in different scenarios were evaluated.…”

Improving the selection of MPRs in OLSR protocol: a survey of methods and techniques

“…the MPRs search procedure launched by the NPC (Node Performing the Computation) makes it possible to detect a set of nodes able to transmit its messages and its data to other nodes far from its range and therefore cover the entire network. The computation of the MPR by the standard algorithm RFC3626 [3] presented below remains basic and insufficient because it does not take into account all the characteristics of the node and the network, for a thorough study of this problem we compared several approaches proposed by researchers in order to improve the quality of service [4,5] and security level [6,7] of this protocol against attacks [8,9].…”
