Abstract: The Sierpinski gasket monopole antenna has been shown to be an excellent candidate for multiband applications. The multiband behavior of the fractal Sierpinski antenna is described in this paper. An analysis is performed to examine the parameters of antenna with a frequency range in between 1 GHz to 6 GHz, at various operating frequency with a VSWR <2 and return loss<-10 dB of similar antenna structures. The single band behaviors of antenna are studied in this paper with an iterative method and try it to convert in multiband antenna. In this paper, proposed antenna is designed to satisfy all the system requirements for DCS1800 (1.71–1.88 GHz), DCS1900 (1.85–1.99 GHz), IMT-2000 (1.885–2.2 GHz), UMTS (1.92–2.17 GHz), WiBro (2.3–2.39 GHz), WLAN (2.4–2.483 GHz), and DMB (2.605–2.655 GHz), simultaneously. All the simulated results are mandatory and satisfactory using HFSS software.

Abstract: Dynamic Source Routing (DSR) [1, 2], which is an on-demand routing protocol, becomes the most popular source routing protocol for MANET. Each mobile node is required to maintain route caches that contain the source routes of which the mobile is aware. Although DSR can respond a route quickly, it yields a long delay when a route is rebuilt. This is because when source node receives RERR packet, it will try to find alternative routes from route cache. If alternative routes are not available, source node, then, will enter route discovery phase to find new routes. Finding a route in wireless network require considerable resources, such as time, bandwidth, and power because it relies on broadcasting. In this paper we introduce a route maintenance strategy as DISTANCE (DIstance baSed rouTe maintenANCE). DISTANCE works by adding another node (called bridge node) into the source list to prevent the link from failure. From the simulation result, DISTANCE improves the performance of DSR in terms
