Avant-garde Security in AODV

چکیده
MANETs are networks formed by moving nodes. They use wireless communication to speak among them and they do it in an ad hoc manner. MANET is considered as an ideal network model for group communications because of its forte of instant establishment. Since, existence of central servers cannot be expected; nodes need to guarantee their data to reach the destination securely without loss, tamper or theft of information. This paper explains and compares two ways to ensure data is securely reached to destination. First approach (iAODV) is designed for MANET where symmetric keys can be made available at time of set up of network. It uses intelligent detection and avoidance of probable malicious nodes occurring in route path by scanning packet tampering. Second approach (fAODV) is designed to deliver the encryption keys through ‘friend’ nodes before sending data packets. The results prove that the whole MANET structure can be upheld at a reasonable security level with practical short convergence time on small computation expenses. More importantly, the security level can be easily customized to meet the varied demands from applications over ad hoc networks.

His model of autonomy and legitimacy in modern art was based on a study of the genesis of an avant-garde in French art in the late nineteenth century. I argue that a similar autonomization of art occurred in the midtwentieth century in the United States. I present studies in ...

a bstr act Reflections on the relationship of aesthetics to politics tend to circle, almost compulsively, around a relatively stable set of conceptual oppositions, inherited from German philosophies of the late 18th century.

متن کاملSchumpeter: Theorist of the avant-garde
This paper argues that Schumpeter’s 1911 edition of ‘Theory of Economic Development’ can be fruitfully read as a theory of the avant-garde, in line with such theories developed by artistic avant-garde around the same time, in particular by the Italian Futurists. In particular it will show that both Schumpeter and other avant-garde theorists sought to break with past (1), identify an avant-garde...
