Wireless Sensor Networks (WSN) is defined as a scattered topology of sensor nodes, sensing the data from the environment, processing and transmitting it to server node. This architecture is comparable to a smart grid application' Advanced Metering Infrastructure (AMI)' where a smart meter(node) serves as a data collecting device and reports the energy usage to the server. Although the IEEE802.15.4/...
Directional communication in Mobile Ad-hoc Networks (MANETs) helps in mitigating the problems of exposed nodes and interference, while providing better spatial reuse. However, use of directional antenna also leads to the problem of deafness. This paper presents a novel method to mitigate deafness in MANETs. In the proposed method, Request To Send (RTS), Clear To Send (CTS), Data and Acknowledgement...
Today, Online audits give profitable data about items and administrations to buyers. On the other hand, spammers are joining the group attempting to deceive pursuers by composing fake surveys. Past endeavors for spammer identification utilized reviewers' behaviors, text similarity, linguistics features and rating patterns. Those studies have the capacity recognize certain sorts of spammers, e.g.,...
Intellectual property information service industry has obtained swift and dramatic development in recent years. However, the majority of intellectual property agencies are small or medium size enterprises which are small-scale, less funding and tech-support, scattered layout, and have strong demands. Cloud-computing as an emerging technology presents significance for small and medium-sized enterprises...

In wireless communication systems like mobile or satellite network a specified band is allotted. Each network has its own allotted spectrum for safe and secure communication. Transferring secure data and receiving it is important and difficult task. Secure transmission of data needs to hide the message signals. Such security to message signal is provided by adding a random noise sequences to it, i...
This paper presents the hardware design procedure (principles and practices) required to convert a specification in the hardware representation of the given design. The paper first examines general design principles required to guarantee optimum performance of the system to be designed such as pipelining and sequencing using finite state machines (FSM). The general hardware design methodology is then...
With the rapid advance in digital network, digital libraries, and particularly WWW (World Wide Web) services, we can retrieve many kinds of information anytime. Thus, security has become one of the most significant problems for distributing new information. It is necessary to protect this information while communicated over insecure channels. Thus a need for developing technology that will help to...
Mobile ad-hoc network (MANET) is the collection of various mobile nodes which are connected together over a wireless medium having no fixed infrastructure. Each participating node in the network acts as both router and host and responsible for forwarding packets for other nodes. Nowadays MANETs are becoming famous for their applications and features. In MANET identifying the security issues is major...
Current era is cyber era, mostly people are dependent on online task, to keep the message secure from the hackers and crackers there is need of strong cryptography. Hackers are becoming intelligent day by day to attack on data as per their experience gain. Cryptography is a private communication in the public world. A cryptosystem should be secure even if the attacker (intruder) knows all the details...
Mobile Cloud Computing is an emerging technology in IT world. With the increasing demand of mobile users in terms of security, resources and computing power leads to necessity of accessing cloud resources in mobile device. Though there are some limitations in smartphones such as limited computing power and energy resources as compared to desktops. CloneCloud can be used as a solution to migrate the...
Quality-sensitive and security concerned applications such as medical images, military images, precious art, law enforcement, and remote sensing do not tolerance slight variation after extraction of watermark. Reversible watermarking has been proposed as a valid solution to enhance security against interception as well as unauthorized modification and to preserve quality of such images. This paper...
Many Floating Point operations have been acknowledged to be useful for many real time graphic and multimedia application as well as DSP processors. Many Digital Signal Processing algorithms use Floating point arithmetic, which requires millions of calculations per second to be performed. For such stringent requirements, design of fast, precise and efficient circuits is the goal. This brief presents...

The schematic has been implemented using UMC-180nm CMOS technology and simulated on spectre-RF simulator of Cadence. The input RF and LO frequency of the proposed mixer is 2.4GHz and 2.25GHz respectively, resulting in...
In this work, we are using voltage scaling to make the counter design as an energy efficient design. The 74163 counter is a 4-bit fully synchronous counter that is available in both TTL and CMOS logic families. In addition to performing the counting function, it can be cleared or loaded in parallel. It has been observed that when different powers have been measured at different frequencies and different...
