EAACK - Enhanced Adaptive Acknowledgment

Wireless networks are currently dominating over wired networks in many applications.Mobility and scalability are some of the features that has led to make wireless networks more popular. Out of the many wireless network Mobile Ad-Hoc network (MANET) are the most popular. They have a highly dynamic and random topology. Essentially the ad hoc network is a collection of nodes communicating with each other by forming a multi-hop network. MANET is used in many military applications because of its self configuring nature. However Mobile Ad-Hoc Network (MANET) has much vulnerability towards security attacks due to its features of open medium, limited physical security, dynamic changing topology, lack of centralized monitoring and organization point.

1.0 INTRODUCTION

The self organizing and self configuring nature of wireless ad hoc network have made it more popular and is widely used in all areas of live application. The Mobile ad hoc network is the commonly used wireless ad hoc network of mobile devices each having the ability to move in all directions and can forward packets dynamically. The proper communication in MANET happens by nodes cooperating with each other. The nodes are added and removed dynamically and this makes the MANET having a dynamic network topology. The communication among nodes within the MANET can be done directly.
