Abstract: MANET is quickly spreading for the property of its capability in forming rapidly changing topologies network without the aid of any established infrastructure or centralized administration. The security challenges in MANET have become a primary concern to provide secure communication. The Attacks on MANET disrupts network performance and reliability. The DOS (denial-of-service), Distributed denial-of-service (DDoS) attacks are a rapidly growing problem. The multitude and variety of both the attacks and the defense approaches is overwhelming. These attacks lead toward the degradation or prevention of legitimate use of network resources. There is a need to provide an incentive or credit based mechanism that can provide cooperation among nodes in the network and improve overall network performance and functionality by prevention, detection and control of DOS and DDOS attacks. Therefore, in this paper, we proposed the detection and control mechanism for DDOS attacks over reputation and score based MANET and a clustering technique uses the reputation and score value of nodes.

International Journal of Computer Science and Management Studies , 2012,
Abstract: Mobile ad hoc networks (MANET) can be defined as a collection of large number of mobile nodes that form temporary network without aid of any existing network infrastructure or central access point. Each node participating in the network, acts both as host and a router and must therefore is willing to forward packets for other nodes. The characteristics of MANET provides large amount of degree of freedom and self-organizing capability that make it completely different from other network. Due to this nature of MANET, design and development of secure routing is challenging task for researcher in an open and distributed communication environments. The main work of this paper is to address the security issue, because MANET is generally more vulnerable to various attacks, so we proposed a secure routing protocol for MANET, named ASRP (Authenticate Secure Routing Protocol) based on DSDV (Destination- sequence distance vector). This protocol is designed to protect the network from malicious and selfish nodes. We are implementing Extended Public key Cryptography mechanism in ASRP in order to achieve security goals.

Abstract: A freely moving nodes forming as group to communicate among themselves are called as Mobile AdHoc Networks (MANET). Many applications are choosing this MANET for effective commutation due to its flexible nature in forming a network. But due to its openness characteristics it is posing many security challenges. As it has highly dynamic network topology security for routing is playing a major role. We have very good routing protocols for route discovery as well as for transporting data packers but most of them lack the feature of security like AODV. In this paper we are studying the basic protocol AODV and identify how it can be made secure. We are studying a protocol S-AODV which is a security extension of AODV which is called Secure AODV (S-AODV) and we are studying enhanced version of S-AODV routing protocol a Adaptive Secure AODV (A-SAODV). Finally we have described about the parameter to be taken for performance evaluation of different secure routing protocols

Abstract: Security issues in MANET are a challenging task nowadays. MANETs are vulnerable to passive attacks and active attacks because of a limited number of resources and lack of centralized authority. Blackhole attack is an attack in network layer which degrade the network performance by dropping the packets. In this paper, we have proposed a Secure Fault-Tolerant Paradigm (SFTP) which checks the Blackhole attack in the network. The three phases used in SFTP algorithm are designing of coverage area to find the area of coverage, Network Connection algorithm to design a fault-tolerant model and Route Discovery algorithm to discover the route and data delivery from source to destination. SFTP gives better network performance by making the network fault free.
A Probabilistic Approach To Reduce The Route Establishment Overhead In AODV Algorithm For Manet

International Journal of Distributed and Parallel Systems , 2012,
Abstract: Mobile Ad-hoc Networks (MANETS) is a collection of wireless nodes without any infrastructure support. The nodes in MANET can act as either router or source and the control of the network is distributed among nodes. The nodes in MANETS are highly mobile and it maintains dynamic interconnection between those mobile nodes. MANTEs have been considered as isolated stand-alone network. This can turn the dream of networking “at any time and at any where” into reality. The main purpose of this paper is to study the issues in route discovery process in AODV protocol for MANET. Flooding of route request message imposes major concern in route establishment. This paper suggests a new approach to reduce the routing overhead during the route discovery phase. By considering the previous behaviour of the network, the new protocol reduces the unwanted searches during route establishment process.

International Journal on Applications of Graph Theory in Wireless ad hoc Networks and Sensor Networks , 2010,
Abstract: Secure multicast communication in Mobile Adhoc Networks (MANETs) is challenging due to its inherentcharacteristics of infrastructure-less architecture with lack of central authority, limited resources such asbandwidth, energy and power. Several group oriented applications over MANETs create new challengesto routing protocols in terms of QOS requirements. In many multicast interactions, due to its frequentnode mobility, new member can join and current members can leave at a time. It is necessary to choose arouting protocol which establishes true connectivity between the mobile nodes. The pattern of movementof members is classified into different mobility models and each one has its own distinct features. It is acrucial part in the performance of MANET. Hence key management is the fundamental challenge inachieving secure communication using multicast key distribution for mobile adhoc networks. This paperdescribes the impact of mobility models for the performance of a new cluster-based multicast treealgorithm with destination sequenced distance vector routing protocol in terms of QOS requirementssuch as end to end delay, energy consumption and key delivery ratio. For simulation purposes, threemobility models are considered. Simulation results illustrate the performance of routing protocol withdifferent mobility models and different mobility speed under varying network conditions.

International Journal of Electronics Communication and Computer Technology , 2012,
Abstract: A freely roaming nodes forming as a group of network for effective communication is called Mobile Ad hoc Networks (MANET). In MANET nodes have the liberty of moving around the network with no defensive boundaries and often nodes join and leave the network as per their need due to this nature MANET’s are insecure. In this insecure environment Routing is a critical aspect which must be done properly for secure and reliable delivery of a data and communication. In order to have a secure system we need design a system which provides security to the mechanism of routing i.e. Route Discovery in a efficient way, Route maintenance with less cost and there should be secure Packet forwarding/delivery. In this paper we are trying to study the mechanism of routing as well as various attacks on functionality of routing. We are also studying different solutions to the various attacks on the routing mechanism of MANET and try to propose a best solution

International Journal of Network Security , 2007,
Abstract: Mobile Ad hoc NETwork (MANET) comprises of nodes, which are free to move randomly, yet cooperate to forward packets between source and destination over a multi-hop wireless network. Due to absence of any fixed node, each node acts as a router, providing routing capability for the MANET. Various protocols for discovery of routes between any two MANET nodes have been designed. These protocols are broadly categorized as on-demand protocols and table driven protocols. Dynamic Source Routing (DSR) and Ad-hoc On-Demand Distance Vector (AODV) are the two most matured on-demand routing protocols, while Optimized Link State Routing Protocol (OLSR) and Topology Dissemination Based on Reverse-Path Forwarding (TBRPF) are the two most matured table driven routing protocols. This paper proposes enhancements in DSR to provide secured route discovery and improved QoS. The paper evaluates integration of Secured Routing Protocol (SRP) and Secured Message Transmission (SMT) with DSR to get Secured Dynamic Source Routing (S-DSR), which is capable of secured route discovery. The proposed extension also incorporates concurrent usage of multiple cached routes for improved throughput and explores possible enrichment to route cache management resulting in improved efficiency. A novel idea of proactive route discovery, particularly for high and sustained bandwidth dependent applications like video conference, voice over IP etc., has been proposed. The paper finally concludes with remarks on a possible comprehensive S-DSR protocol, incorporating better route cache maintenance scheme, proactive route discovery and integration of SRP/SMT features for secured route discovery and secured data transmission.
