Secure Routing in Wireless Adhoc Networks

Abstract

The growth of the information technology requires effective transmission of information from source to destination nodes Due to the importance of the information broadcasting Mobile Adhoc Networks MANET has become the communication system of choice for most broadcast applications The MANET consists of a collection of infrastructure and self configuration nodes which effectively transmit the information in the mobile platform In addition to this the MANET provides the mechanism for every user to directly interact with the base station while transmitting the information In this process packet broadcasting was one of the major functions because it transmits the packets to entire nodes in the network The developed information broadcasting infrastructure plays a crucial role indifferent applications such as emergency services home applications education institutions military applications and so on The MANET includes various characteristics such as self creation multihop routing self organization light weight terminals distributed operations autonomous terminal and self administration Inspite of these characteristics the MANET needs to handle other issues while routing the information from source to destination because the presence of an unhealthy route leads to several problems such as node failure link failure packet failure changes in topology misleading nodes selfish nodes transmission error and congestion Because of these issues route identification between source and destination node is one of the major challenges in Mobile Adhoc v Networks Hence several methods have been developed in MANET for creating effective and optimized routes for overcoming the above difficulties newline
