Ant Based Techniques for QoS Routing in Mobile Ad Hoc Network: An Overview

-------------------------------------------------------------------ABSTRACT-------------------------------------------------------------Mobile Ad Hoc Network (MANET) is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any existing heterogeneous network infrastructure. Quality of Service (QoS) support for MANET is a challenging task due to dynamic topology and limited resource. The main purpose of QoS routing is to find a feasible path that has sufficient resources to satisfy the constraints. Ant based technique is a stochastic approach for solving optimization problems like routing in mobile ad hoc networks. This technique is based around on the study of collective behavior in decentralized self organized system. In this paper we describe an overview of the research carried out in Ant Based QoS routing for MANET.
