A Novel Model for Implementing Security over Mobile Ad-hoc Networks using Intuitionistic Fuzzy Function

Authors: A. A. Salama
Comments: 7 Pages.

Abstract: Mobile adhoc network is a special kind of wireless networks. It is a collection of mobile nodes without having aid of establish infrastructure. In mobile adhoc network, it is much more vulnerable to attacks than a wired network due to its limited physical security, Securing temporal networks like Mobile Ad-hoc Networks (MANETs) has been given a great amount of attention recently, though the process of creating a perfectly secured scheme has not been accomplished yet. MANETs has some other features and characteristics those are together make it a difficult environment to be secured. The bandwidth of MANET is another challenge because it is unlikely to consume the bandwidth in security mechanisms rather than data traffic. This paper proposes a security scheme based on Public Key infrastructure (PKI) for distributing session keys between nodes. The length of those keys is decided using intuitionistic fuzzy logic manipulation. The proposed algorithm of Security-model is an adaptive intuitionistic fuzzy logic based algorithm that can adapt itself according to the dynamic conditions of mobile hosts. Finally the Experimental results shows that the using of intuitionistic fuzzy based security can enhance the security of (MANETs).

Neutrosophic Relations Database

Authors: A. A. Salama
Comments: 13 Pages.

The fundamental concepts of neutrosophic set, introduced by Smarandache in [9, 10] and Salama et al. in [4, 6, 7, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18]. In this paper we introduce and study new types of neutrosophic concepts "  cut levels , normal neutrosophic set, convex neutrosophic set". Added to we will begin with a definition of neutrosophic relation and then define the various operations and will study its main properties. Some types of neutrosophic relations and neutrosophic database are gevine. Finaly we introduce and study neutrosophic database (NDB for short). Some neutrosophic queries are gevine to a neutrosophic database .

Critical Considerations for Developing MIS for NGOs

Authors: Kailash Ch. Dash, Umakant Mishra
Comments: 13 Pages.

Although Information Systems and Information Technology (IS & IT) has become a major driving force for many of the current day organizations, the NGOs have not been able to utilize the benefits up to a satisfactory level. Most organizations use standard office tools to manage huge amount for field data and never feel the need for a central repository of data. While many people argue that an NGO should not spend too much money on information management, it is a fact that organizing the information requires more of a mindset and an organized behavior than a huge financial investment.
