Paperback. Mobile Ad Hoc Networks (MANETs) are infrastructure-less, self-organizing networks where all nodes act as routers and participate in route discovery and maintenance. This decentralized and dynamic nature, while highly flexible, introduces significant challenges including node mobility, limited bandwidth and power, and security vulnerabilities. Routing protocols are the backbone of MANETs, but they are frequently targeted by malicious nodes, making secure communication a critical concern. The widely used Ad-hoc On-Demand Distance Vector (AODV) routing protocol efficiently establishes routes on demand using sequence numbers and hop counts, but it was originally designed without security in mind. Its control packets, transmitted in clear text, can be manipulated by attackers, enabling unauthorized nodes to advertise false routes and disrupt network operations. To address these vulnerabilities, this research focuses on enhancing the security of AODV using lightweight cryptographic mechanisms. Two novel schemes are proposed: a Message Digest Mechanism and a Message Digest with Secret Key Mechanism, designed to ensure integrity and authenticity of routing messages while maintaining low computational overhead and minimal power consumption. Existing secure protocols, such as SAODV, provide partial solutions but often introduce higher complexity or fail under high traffic conditions. The proposed schemes integrate message digest techniques to protect against malicious attacks, offering a practical and efficient security solution for dynamic MANET environments. The performance of these mechanisms is evaluated using NS2 simulations under varying network scenarios and traffic loads, including Constant Bit Rate (CBR) traffic. Results demonstrate that under low traffic, AODV with the proposed mechanisms performs comparably to SAODV in terms of packet delivery and routing load. As traffic increases, the proposed solutions outperform SAODV, achieving higher packet delivery ratios, reduced routing overhead, and improved routing efficiency. These findings indicate that the proposed mechanisms are scalable, energy-efficient, and effective in securing MANET routing protocols. This item is printed on demand.

Synopsis

Mobile Ad Hoc Networks (MANETs) are infrastructure-less, self-organizing networks where all nodes act as routers and participate in route discovery and maintenance. This decentralized and dynamic nature, while highly flexible, introduces significant challenges including node mobility, limited bandwidth and power, and security vulnerabilities. Routing protocols are the backbone of MANETs, but they are frequently targeted by malicious nodes, making secure communication a critical concern. The widely used Ad-hoc On-Demand Distance Vector (AODV) routing protocol efficiently establishes routes on demand using sequence numbers and hop counts, but it was originally designed without security in mind. Its control packets, transmitted in clear text, can be manipulated by attackers, enabling unauthorized nodes to advertise false routes and disrupt network operations. To address these vulnerabilities, this research focuses on enhancing the security of AODV using lightweight cryptographic mechanisms. Two novel schemes are proposed: a Message Digest Mechanism and a Message Digest with Secret Key Mechanism, designed to ensure integrity and authenticity of routing messages while maintaining low computational overhead and minimal power consumption.

Right of withdrawal

If you are a consumer you can withdraw from the contract in accordance with the following. Consumer means any natural person who is acting for purposes which are outside his trade, business, craft or profession.

Information regarding the right of withdrawal

Statutory right to withdraw

You have the right to withdraw from this contract within 14 days without giving any reason.

The withdrawal period will expire after 14 days from the day on which you acquire, or a third party other than the carrier and indicated by you acquires, physical possession of the last good or the last lot or piece.

To exercise the right of withdrawal, electronically fill in and submit a clear statement on our website, under "My Purchases" in "My Account". We will communicate to you an acknowledgement of receipt of such a withdrawal on a durable medium (e.g. by e-mail) without delay.

To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.

Effects of withdrawal

If you withdraw from this contract, we will reimburse to you all payments received from you, including the costs of delivery (except for the supplementary costs arising if you chose a type of delivery other than the least expensive type of standard delivery offered by us).

We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the result of unnecessary handling by you.

We will make the reimbursement without undue delay, and not later than 14 days after the day on which we are informed about your decision to withdraw from this contract.

We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.

We may withhold reimbursement until we have received the goods back, or you have supplied evidence of having sent back the goods, whichever is the earliest.

You shall send back the goods or hand them over to Grand Eagle Retail, Bensenville, Illinois, U.S.A., without undue delay and in any event not later than 14 days from the day on which you communicate your withdrawal from this contract to us. The deadline is met if you send back the goods before the period of 14 days has expired. You will have to bear the direct cost of returning the goods. You are only liable for any diminished value of the goods resulting from the handling other than what is necessary to establish the nature, characteristics and functioning of the goods.

Exceptions to the right of withdrawal

The right of withdrawal does not apply to:

The delivery of newspapers, journals or magazines with the exception of subscription contracts; and
The supply of digital content which is not supplied on a tangible medium (e.g. on a CD or DVD) if you accepted when you placed your order that we could start to deliver it, and that you could not withdraw once delivery had started.

Shipping Terms
