An Approach towards Seamless Handover with Maximum Resource Utilization in Mobile Wireless Networks
Abstract: ABSTRACT In mobile wireless networks, a seamless handover between different communication systems has been a challenging issue. A link going down (LGD) event based on L2 layer information has been incorporated by the IEEE 802.21, media independent handover (MIH) framework. Link going down trigger allows accomplishing handover efficiently with the prior intimation of handover and enables L3 entities streamline their handover (HO) related activities. As velocity of user has a …

Analysis of N-Slot Loaded Patch Antenna for Tripple Band Operation
Abstract: ABSTRACT In this paper, the analysis of N-slot loaded microstrip antenna having single and double dielectric layer with coaxial feeding is presented using circuit model analysis. The antenna gives triple resonance and the separation between these resonances depends on the dimension of the slot. This antenna gives wide bandwidth for all three resonant frequencies for single dielectric and gives four bandwidths for double dielectric layer. It is observed that the …

Comparison of Ultra Wide Band Indoor Multipath IEEE 802.15.3 Channel Model
Abstract: ABSTRACT A very large bandwidth of frequency (3.1–10.6 GHz) has been allocated to UWB systems. A single-band UWB signal propagates differently in the lower and upper bands of the spectrum due to the size of its bandwidth. The lower part of the signal can be obstructed more easily and the man-made interferences are not homogeneously distributed over the whole spectrum. The first experimental results obtained for a UWB channel show …

Design and Implementation of Real-time Security System in Highly Crowded Zone on Embedded Platform
Abstract: ABSTRACT The gist of this paper is to find answer to a very fundamental question: How safe and free are we as individuals? If not, then how the latest technologies can be used to make us safe and free. This question looks very simple but it is one that is attracting the interest of both the normal human beings like us and the technologists who spend their lifetime to make …

Microstrip Leaky-Wave Antenna with Reduced Ground Plane
Abstract: ABSTRACT This paper is aimed to find the microstrip leaky-wave antenna. The above antenna has become interesting due to its simple shape and geometry. This paper uses a reduced ground plane which can improve the bandwidth of the proposed antenna. This antenna has been simulated on CST-microwave suit software and got fabricated on PCB. The simulated measurements show that the proposed antenna achieves an operating bandwidth of 800 MGHz for …
