A Survey on Data Transmission Security in MANETs
An ad-hoc network is a collection of mobile nodes equipped with wireless communication adapters. These nodes dynamically form a temporary network without the need of any existing network infrastructure. Nodes in MANETs use radio signals with a finite range to communicate making it possible for any intermediate node to intercept the communication. Also the frequently changing topology, with high...
متن کاملModeling Nonnegative Data with Clumping at Zero: A Survey
Applications in which data take nonnegative values but have a substantial proportion of values at zero occur in many disciplines. The modeling of such “clumped-at-zero” or “zero-inflated” data is challenging. We survey models that have been proposed. We consider cases in which the response for the non-zero observations is continuous and in which it is discrete. For the continuous and then the d...
متن کاملAsymmetric Price Transmission: A Survey
Asymmetric price transmission has been the subject of considerable attention in agricultural economics. It is not only important because it may point to gaps in economic theory, but also because its presence is often considered for policy purposes to be evidence of market failure. In this paper we survey the literature on asymmetric price transmission. A wide variety of often conflicting theori...
متن کاملA Faunistic Survey of Cercariae Isolated from Melanoides tuberculata and Their Role in Transmission Diseases.
To funistic survey of the cercariae of Melanoides tuberulata (fresh water snail) 1540 M.tuberculata were collected from various streams, swamps, ditches and canals in the central area of Khouzestan province in the south west of Iran. Infected snails, 46 (2.9%), were isolated and cercariae were obtained by emerging or crushing methods and then measuring and drawing were made from specimens. In s...
