Optoelectronic properties of zinc blende and wurtzite structured binary solids

  In this paper, we studied zinc blende (ZB) and wurtzite (Wu) type structured binary solids with conduction electrons and calculated the optoelectronic properties such as high frequency refractive index (n), optical susceptibility (χ), electronic polarizability (αe) and crystal ionicity (fi) using the plasma oscillation theory of solids formalism already employed for ternary chalcopyrite...

Comparison and performance analysis of reactive type DSR, AODV and proactive type DSDV routing protocol for wireless mobile ad-hoc network, using NS-2 simulator

  Routing in MANET is a critical task due to highly dynamic environment. A routing protocol is needed whenever a packet needs to be transmitted to destination via number of nodes and numerous routing protocols have been proposed for ad-hoc network. In this paper we try to judge the impact of both reactive as well proactive type protocols by increasing the density of nodes in the network, keeping...
