SO-AODV: A Secure and Optimized Ad-Hoc On-Demand Distance Vector Routing Protocol Over AODV With Quality Assurance Metrics for Disaster Response Applications

摘要

MANET has emerged as an eager field for supporting disaster response and prevention applications like climate and weather observation, tracking, tsunamis, wildfire and emergency rescue operations, underwater level navigation, etc. In this paper, a new ad-hoc routing protocol named SO-AODV (Secured and Optimized Ad-Hoc On-Demand Distance Vector) is proposed for secured and optimized communication in any disaster like situations. For shortest route selection a technique called pigeons swarm optimization (PiSO) is used that also leads to minimize the hop count in selected optimal route. Lightweight digital watermarking (LDW) is used that ensures the authenticity of "hello" packets. For security of event messages, cyphertext stealing technique (CST) is used with encryption qu-Vanstone elliptic curve cryptography (qV-ECC) based public key cryptography. The qV-ECC generates public key. Experiments are conducted using NS2 and performance is evaluated and compared over AODV for several metrics (i.e., packet delivery ration, throughput, end-to-end delay, security, and hop count).
