An effective implementation of security based algorithmic approach in mobile adhoc networks

Abstract

Mobile Ad-hoc Network one of the prominent area for the researchers and practitioners in assorted domains including security, routing, addressing and many others. A Mobile Ad-hoc Network (MANET) refers to an autonomous group or cluster of mobile users that communicate over relatively bandwidth constrained wireless links. Mobile ad hoc network refers to the moving node rather than any fixed infrastructure, act as a mobile router. These mobile routers are responsible for the network mobility. The history of mobile network begin after the invention of 802.11 or WiFi they are mostly used for connecting among themselves and for connecting to the internet via any fixed infrastructure. Vehicles like car, buses and trains equipped with router acts as nested Mobile Ad-hoc Network. Vehicles today consists many embedded devices like build in routers, electronic devices like Sensors PDAs build in GPS, providing internet connection to it gives, information and infotainment to the users. These advances in MANET helps the vehicle to communicate with each other, at the time of emergency like accident, or during climatic changes like snow fall, and at the time of road block, this information will be informed to the nearby vehicles. Now days technologies rising to provide efficiency to MANET users like providing enough storage space, as we all know the cloud computing is the next generation computing paradigm many researches are conducting experiments on Mobile Ad-hoc Network to provide the cloud service securely. This paper attempts to propose and implement the security based algorithmic approach in the mobile adhoc networks.

Node Disjoint Random and Optimal Path Selection (NDROPS) Algorithm for Security in MANETS

“…Another type of routing technique which is based on Alpha numeric [17] was proposed. Nodes in a network are classified as leader nodes and active nodes, where leaders are used to monitor the active nodes.…”

Implementing Security Features in MANET Routing Protocols

“…Thus, a network-layer protocol that is designed for self-configuring networks should have rules that are enforced for connectivity and security requirements to make sure that the higher layer protocols are operating at an optimum level. [1] Sadly the scenario is that most often used ad-hoc routing protocols have almost no security considerations and they blindly trust all the MANET participants to forward routing and data traffic in a correct manner. The above mentioned assumption sometimes proves disastrous for a mobile ad hoc network that trusts blindly its intermediate nodes for packet forwarding.…”

“…While, cure is defined as the ability to mitigate the effects of the anomalous behaviour of the node." [1] Some possible attacks that are carried out on MANETs are eavesdropping on a node, compromising a node, distortion of messages relayed by a node, reply of messages by a node, failure to forward messages from a node, jamming of MANET radio frequency signals etc. The main issues that are responsible for the possible attacks and any security lapse in MANETs are confidentiality, authentication, availability, integrity, nonrepudiation and trustworthiness.…”

“…The main focus of this paper is to show that, how a tiny novel approach of including hashing algorithm like SHA3 can enhance security and reliability in MANETs. [1] The scope of securing MANETs is as follows, but it is not limited to these approaches:…”

“…The main issues that are responsible for the possible attacks and any security lapse in MANETs are confidentiality, authentication, availability, integrity, nonrepudiation and trustworthiness. [1] The basic mobile ad-hoc networks depend on some fixed accesses point or other mobile node (in case of MANETs) for communication via sending and capturing packets. When one compares wired ad-hoc networks with MANETs, wired networks have a proper infrastructural set up for sending, forwarding, and capturing packets.…”
