Abstract: A mobile ad hoc network (MANET) is a type of ad hoc network newlinethat can change locations and configure itself on the fly. Since MANETS are newlinemobile, they use wireless connections to connect to various networks. quotAd newlineHocquot is actually a Latin phrase that means for this purpose . It is often used newlineto describe solutions that are developed on-the-fly for a specific purpose. The newlineMANET, which is an ad hoc network, is an infrastructure-less, mobile, newlinemultihop, ubiquitous, and dynamic topology network. Due to these newlinecharacteristics of MANETs and their open medium and distributed newlinecooperation, ad hoc networks are more vulnerable to many types of security newlineattacks. Hence, security becomes an important issue in wireless networks. The unique characteristics of MANET combined with security newlineissues has become the primary concern for researchers to meet challenges, newlinesuch as confidentiality, authentication, integrity, availability, access control newlineand non-repudiation. The main objective of this thesis is to propose new newlinetechniques to improve the routing mechanism, by detecting and eliminating newlinevarious routing attacks, and determine the performance metrics, such as newlinepacket delivery ratio, throughput, end-to-end delay, control overhead etc. The newlinesimulation result shows that the proposed scheme is more resilient than the newlineexisting schemes. The thesis focuses on two aspects. Initially, different types newlineof attacks are handled by devising a node transition based routing algorithm that can overcome all possible threats in MANETs, and can also maximize the newlinebandwidth utilization at high traffic costing a lesser overhead. The need for newlinerouting algorithm that consumes less overhead, and at the same time, is secure newlineagainst all possible threats, especially at higher traffics, is the main motivation newlinebehind devising such routing algorithm. Secondly, new routing attacks are newlinestudied, and implemented, and a new algorithm is proposed for overcoming newlinesuch attacks, using the Ad hoc On-demand Distance Vector protocol and the newlineDynamic Source Routing protocol.
