The FCC (Federal Communication Commission) permitted UWB (Ultra Wide Band) operation and UWB devices FCC’s spectrum allocation for UWB is from 3.1GHz to 10.6GHz. UWB has the high data rate transmission nearly of 500 Mbps. In this paper, T shaped antenna for ultra-wide band communication is designed. Both the antennas have modified ground planes. The ...

Initialization of transmitter parameters can be done locally by setting values on the transmitter itself or remotely using a PC. A radio transmitter design has to meet certain requirements. These include the frequency of operation, the type of modulation, the stability and purity of the resulting signal, the efficiency of power use and the power ...

One of the fundamental aspects of ubiquitous computing is the instrumentation of the real world by smart devices. This instrumentation constitutes an opportunity to rethink the interactions between human beings and their environment on the one hand and between the components of this environment on the other. In this paper, the authors discuss what this ...

Among many fundamental communication primitives in mobile ad hoc networks, 1-hop broadcast plays a significant role in which a message from the source node is delivered to all nodes within the source node’s transmission range. Although, the importance of it 1-hop broadcast is not easy to accomplish due to collisions in wireless networks known as ...

In this paper, the authors evaluate the performance of the OLSR pro-active protocol with and without backup routes under varying node densities and with different speed movements in the network. Additionally, this paper assists in ascertaining the effect of varying node densities on the connectivity’s life between mobile nodes in the network. Hence, it showed ...

Wireless communication is widely adopted and application oriented technology There are a huge literature about Mobile Ad-hoc NETwork (MANET) is available. In these studies, the ad-hoc network has two major issues security and performance. In this paper, a feasible and adoptable solution is introduced for enhancing security in MANET. The presented paper utilizes the network ...

In this paper, the authors consider a scenario where nodes in a MANET disseminate data chunks using rate-less codes. Any node in MANET is able to successfully decode any chunk by collecting enough coded blocks from several other nodes without any coordination. Here the problem is to identify malicious nodes that launch a pollution attack ...

Software defined radio implementation is required for LTE (Long Term Evolution) radio transceivers. An SDR (Source Demand Routing) consists of an rf front end and a Digital Processor Platform (DSP). This paper is devoted to the design and implementation of the passive part of the front end; the antennas and bandpass filters. It presents the ...

Mobile Ad-hoc NETwork (MANET) has emerged as a new edge of technology to provide anywhere and anytime communication. Due to its deployment nature, MANETs are more susceptible to malicious attack. Due to the absence of centralized administration, security is the main issue in mobile ad-hoc network and attackers are very easily modified the actual behavior ...

As technology is growing day-by-day. Antenna is fabricated near the ground plane, which affects the overall efficiency of the antenna. In this paper, the wide band antenna with broad bandwidth that can be utilized in different frequency band. Band covers from 750 to 5000 MHZ and GSM, UMTS, Bluetooth, GPS & Wi-Fi applications is examined. ...
