A Review on Trust Model in Vehicular Ad Hoc Network
Pallavi Agarwal,Neha Bhardwaj 보안공학연구지원센터 2016 International Journal of Grid and Distributed Comp Vol.9 No.4
In vehicular ad hoc network (VANETs), the applications mainly focused on the road and making their journey safe and comfortable to fulfill the users’ requirements. It is a challenging subclass of Mobile Ad-hoc Network, which empowers smart transmission among vehicles and between vehicles and roadside frameworks. It is an optimistic methodology for the Intelligent Transport System (ITS). There are numerous difficulties to be tended while utilizing VANET. It is flexible and has a high dynamic topology and flexibility which makes the conventional MANET protocols unacceptable for VANET. Trust is a principal element which is used to create a trustful environment to improve the security in vehicular networks. Trust can be calculated by observing the human behavior which creates a trusted communicating environment. In this paper, we define the architecture of VANET, then the communication establishment and various challenges. Some trust models had been defined in this paper to enforce honest information sharing between communicating nodes. Trust establishment is compulsory among communicating vehicles to build a secure messages exchange and reliability.
Vehicular Ad Hoc Networks : Hashing and Trust Computation Techniques
Pallavi Agarwal,Neha Bhardwaj 보안공학연구지원센터 2016 International Journal of Grid and Distributed Comp Vol.9 No.7
Vehicular ad-hoc networks (VANETs) technology has come out as an important research field over the last few years. VANETs are the likely an influencing approach to provide safety of driver and other applications for the traffic conditions as well as passengers. Being dynamic in nature, it establishes the network, according to the situation and need of the users and provides reliable communication among the vehicles. Due to its great benefits, it is highly vulnerable to various attacks and security in VANET should be taken into consideration. This paper presented the security attacks between vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I). Many research works have been done to improve the performance and security of this network. The main aim of this paper is the security using hashing and techniques to calculate the trust in VANETs.
Second Order Nonsmooth Multiobjective Fractional Programming Problem Involving Support Functions
Pallavi Kharbanda,Divya Agarwal,Deepa Sinha 한국전산응용수학회 2013 Journal of applied mathematics & informatics Vol.31 No.5
In this paper, we have considered a class of constrained nonsmoothmultiobjective fractional programming problem involving supportfunctions under generalized convexity. Also, second order Mond Weir typedual and Schaible type dual are discussed and various weak, strong andstrict converse duality results are derived under generalized class of secondorder (F, α, ρ, d)-V-type I functions. Also, we have illustrated through nontrivialexamples that class of second order (F, α, ρ, d)-V-type I functionsextends the definitions of generalized convexity appeared in the literature.

Kharbanda, Pallavi,Agarwal, Divya,Sinha, Deepa The Korean Society for Computational and Applied M 2013 Journal of applied mathematics & informatics Vol.31 No.5
In this paper, we have considered a class of constrained non-smooth multiobjective fractional programming problem involving support functions under generalized convexity. Also, second order Mond Weir type dual and Schaible type dual are discussed and various weak, strong and strict converse duality results are derived under generalized class of second order (F, ${\alpha}$, ${\rho}$, $d$)-V-type I functions. Also, we have illustrated through non-trivial examples that class of second order (F, ${\alpha}$, ${\rho}$, $d$)-V-type I functions extends the definitions of generalized convexity appeared in the literature.
