A Wireless Sensor Network is a network of sensors that senses specified parameter(s) related to environment; processes data locally or in a distributed manner and wirelessly communicates information to central Base Station. The Base Station analyzes information and initiates suitable response if required. The complexities introduced by severely limited processing capabilities, memory and power supply...
Digital Watermarking is an emerging copyright protection technology. The paper presents a new robust watermarking technique based on combining the power of transform domain technique, the Discrete Cosine Transform (DCT) and the data mining technique such as Decision Tree Induction (ID3). The paper focuses on a technique through which the notion of decision tree can be applied on transformed vectors...
Adhoc sensor networks are being considered for many novel applications. There are many challenges while designing the sensor based adhoc network but main constraint is the power consumption done by the sensor nodes. Many solutions have been proposed to save the power of the senor nodes which are based on routing and other methodology. Most of the studies have considered switching off of the radio...
As AND-XOR network results in much better realization and requires fewer product terms than AND-OR realization, it network has encouraged researchers to look for efficient minimization and synthesis tools for their realization. Among several canonical representations of AND-XOR networks, popular and most testable one is the fixed polarity Reed Muller (FPRM) form. In this paper we have used GA (genetic...
Among the power-aware circuit synthesis techniques that have been proposed so far, power-gating has traditionally been the most effective way to lower power. In this approach, power reduction is achieved by shutting off the power supply to some portions of the logic block which are not active. So, we have to partition the design into two or more power islands. Suitable Finite State Machine partitioning...
In this paper we present a heuristic based on Genetic Algorithm to realize multi-output Boolean function as three-level AND-OR-XOR networks along with area power trade-off. All the previous works dealt with the minimization of number of product terms only in the two sum-of-product-expressions representing a Boolean function during AND-OR-XOR network synthesis. To the best of our knowledge this is...
Power-gating is an effective technique for reducing standby leakage power and dynamic power. In power-gating one can shut off the power supply to sections of logic block while keeping other logic blocks active. However, careful design is required to make power-gating technique effective, otherwise, negative effect of power-gating may overwhelm the potential gain. In this paper we have presented the...
Multimedia traffics are conquering the computer networks. The multimedia communication system requires, the router's forwarding plane to forward the packet according to their QoS requirement. The computer network is an emerging challenge for the open source community. The paper covers mainly two basic components. The first is related to the installation and configuration aspects for implementing DiffServ...
Binary decision diagrams (BDDs) play an important role in the synthesis, verification, and testing of VLSI circuits. In this paper, we have proposed a new BDD-based synthesis technique using dual rail static differential cascode voltage switch with pass gate (DCVSPG) logic. The method yields around 22% reduction in number of MUX cells. Simulation result using SPICE on 180 nm technology with 1.5 volts...
Binary decision diagrams (BDDs) play an important role in the synthesis, verification, and testing of VLSI circuits. In this paper, we have proposed a new BDD-based approach for the synthesis of dual-rail adiabatic MUX circuits. The method yields around 22% reduction in the number of MUX blocks for several benchmark circuits compared to the conventional approach. Simulation result using SPICE on 180...
This paper introduces a systematic approach to design and realize a two-legged robot. Design and system configuration of a two legged robot are explained in detail. Development process of the robot has been divided in to three phases, (1) design (2) verification and (3) realization, while robot's architecture consists of three subsystems, (1) mechanical subsystem (2) electronics subsystem and (3)...
