Surface modes in air-core photonic band-gap fibers
Hollow-core photonic band-gap fibers (PBGFs) are typically made up of a periodic array of air holes in glass, surrounding an air core. These fibers have attracted considerable interest because they hold the promise of exhibiting lower attenuation and lower nonlinearity than conventional glass-core fibers. The potential for lower attenuation derives from the lower absorption and […]
Loss analysis of air-core photonic crystal fibers
Recently the use of Bragg ref lection to conf ine light in an air-core f iber has attracted considerable attention. Some advantages of air-core f ibers are their potential to achieve propagation losses of less than 0.2 dBkm (the current value of telecommunication f ibers) and to greatly increase the power threshold for the onset […]
Scenario-based Performance Analysis of Routing Protocols for Mobile Ad-hoc Networks
This study is a comparison of three routing pro- tocols proposed for wireless mobile ad-hoc net- works. The protocols are: Destination Sequenced Distance Vector (DSDV), Ad-hoc On demand Distance Vector (AODV) and Dynamic Source Routing (DSR). Extensive simulations are made on a scenario where nodes moves ran- domly. Results are presented as a function of […]
