Performance Analysis of On-Demand Routing Protocols in MANETs Using (SHSP-EA3ACK) Algorithms

Mobile Adhoc Networks (MANETs) require a reliable, efficient, scalable routing and most importantly, every single node in the MANETs works as both receiver and transmitter within their communication range. As they are highly secure, self-organizing, rapidly deployed, they use dynamic routing to access information and services anywhere regardless of their geographic location. MANETs are the significant technologies among various air communication technologies where all the nodes are mobile and can be connected dynamically using wireless link in a random manner. All nodes work router and maintain routes to other nodes in the network. Introduction of the Enhanced Adaptive 3 Acknowledgement (EA3ACK) is to prevent the attacker from forging acknowledgement packets. In this paper recent research, a new intrusion detection system, EA3ACK using EAACK (DSA) with Secure Hybrid Shortest Path (SHSP) Routing is specially designed for MANETs to reduce end-to-end delay. ACK method is implemented to avoid any type of attacking model on the network with secure hybrid shortest path routing algorithm besides avoiding delay and packet loss, it increases the node speed also. Network Simulator (NS2) is used to simulate the proposed method and implemented in the test system.
