Vehicular Ad hoc Network (VANET) is the network among vehicles. The efficient routing protocol is required to route the data from source node to destination node in VANET. In existing protocols, Ad hoc On-Demand Multipath Distance Vector (AOMDV) the number of hops increases with data traffic and Secure Ring Broadcast (SRB) routing protocol the routes established are very stable but cannot adapt to engaged nodes circumstances. A new concept protocol, Multipath Reliable Range Node Selection Distance Vector (MRRNSDV) routing is proposed which will be multipath protocol and number of hops will remain same even at high traffic conditions. This protocol is basically proposed to reduce the number of hops, find multiple paths to destination node and avoid channel congestion in more efficient way to increase the performance under higher traffic condition unlike Ad hoc on demand distance vector (AODV) protocol. © 2014 IEEE.

Vehicular Ad hoc Network (VANET) is the network of vehicles and road side units. The effective routing protocol is needed to route the data from source node to destination node in VANET. In available protocols, Directed Route Node Selection (DRNS) cannot detect the nodes movement in multiple directions for routing and in Ad hoc On-Demand Multipath Distance Vector (AOMDV) the route are not much stable. But DRNS is unable to detect nodes movement in other directions and specifically suited for the highway scenarios. A novel protocol, Acute direction Route Node Selection Multipath (ADRNSM) routing is proposed which is multipath protocol and adapt to 16 different directions of movement. This protocol is basically introduced to be aware of movement direction and engage nodes moving only in specific direction for routing to destination node. This protocol finds multiple paths to destination node and avoids engaging the nodes moving in other directions to increase the performance in urban scenario unlike DRNS protocol. © 2014 IEEE.

For any type of steganography there is always a trade-off between information hiding capacity and security. In this paper we have proposed a new video steganography technique using forensic detection to improve information security and hiding capacity. For hiding secret data into the selected frames of video and audio, we have used general modified EMD algorithm for image steganography and speared spectrum algorithm for audio steganography and it is found to be excellent in terms of hiding capacity and security. Further at receiver end we have retrieved a secret data from the video and analyse the key security parameters to increase the data security. Our new approach efficiently hides large data and produces more security. We have tested our results through a number of simulations on gray as well as colour images and found the proposed algorithm to be better than any other existing technique.

Performance of a production system significantly depends upon the effective planning of its shop floor level operations like, production scheduling, maintenance and quality control. These three functions have an interaction effect on each other; hence a combined operational policy of these functions can improve the system performance. The objective of this paper is to develop a methodology for optimizing maintenance and quality plan with the constraint on schedule, availability, repair time and detection time, for a single machine. The approach includes the selective maintenance and a sampling procedure based on the economic design principle. Cost models developed for the problem at hand are presented along with their detailed explanation. Two solution methodologies namely, Simulated Annealing (SA) and Genetic Algorithm (GA) are used for obtaining the near optimal solution. A computational experiment to compare the performance of SA and GA is presented. Results indicate a better performance of the proposed approach over the conventional approach of independent planning. © 2015 The Society of Manufacturing Engineers. Published by Elsevier Ltd.

The complexity of many image processing applications and their stringent performance requirements have come to a point where they can no longer meet the real time deadlines, if implemented on conventional architectures based on a single general-purpose processor. Acceleration of these algorithms can be done by parallel computing. Parallelism can be accomplished both at hardware and software levels by various tools and methodologies. The various methods hence discussed prove to be helpful and thus a combination of both the custom hardware and software tool helps in speeding up the image processing algorithm. Different methodologies that can be used for parallel computation are discussed. © 2016 IEEE.

In order to support a wide set of communication standards and to accommodate different applications in a single device, broadband receivers are essential and inevitably in demand. A wideband low-noise amplifier (LNA), which is a key block in the design of broadband receivers for multiband wireless communication standards, is proposed. A differential common-gate (CG) LNA utilizing multiple-feedback technique is presented. The multiple-feedback technique adds degrees of freedom in the choice of the LNA transconductance to reduce the noise figure (NF) and increase the amplification. It avoids the use of bulky inductors resulting in considerable area and cost savings. The LNA is designed and simulated in 180 nm CMOS technology. It covers the frequency range of 0.8 GHz to 2 GHz. The designed and simulated LNA delivers a maximum voltage gain of 12.2 dB, a minimum NF of 2.56 dB, a third-order input intercept point IIP3 of -6.5 dBm and 3.6 mW of power consumption with input matching (S11< -10 dB). © 2015 IEEE.

Recently wireless sensor network (WSN) is very popular for monitoring the remote or hostile environments. One major challenge in WSN is to build energy efficient network with total coverage & connectivity. The WSN consist of a large number of tiny nodes having sensing, computation & communication capability. The deployment of sensor nodes is the first step in establishing a sensor network. The large number of sensor nodes are deployed randomly & must be in the form of cluster, as a location of each particular node cannot be fully guaranteed a priori so that nodes must completely cover the target area. To build energy efficient network with the stochastically placed nodes, it is necessary to activate only vital number of nodes at any particular moment. In this paper we introduce a heuristic that will find out the mutually exclusive set called disjoint complete set of sensor nodes, where the member of each set together will completely cover the target area and work by turns. As the more number of sensor covers can be found the sensorsnetwork lifetime can be prolonged. © 2014 Springer.

Recently the application of wireless sensor network (WSN) is very popular for monitoring the remote or hostile environments. Network lifetime is the critical characteristic in wireless sensor network. In large scale reconnaissance system the lifetime of wireless sensor network (WSNs) system is the time period that all targets can be covered. Target coverage problem is one of the issues to increase the lifetime of wireless sensor network. This problem can be solved by scheduling the sensors activity by keeping minimum number of nodes active at particular time. The sensors from the active sets are monitoring all targets and liable to transmit the data to the base station and the remaining nodes are in sleep mode. In this paper we propose Genetic Algorithm in which we keep minimum number of nodes active by forming set cover by divide all the deployed sensors in to mutually elite subsets of sensors or set cover such that each set of can cover all targets. After finding the set cover they may work by turns means at one time only one set will active and other will sleep mode by designing heuristics that efficiently compute the set covers hence lifetime of WSNs can be prolong by finding more sensor set. The simulation results presented to verify the approach the maximum number of sensor cover can be found by conversion to the Cover Set problem, which has been proved to be NP-complete. © 2014 IEEE.

The density of integration in a single chip has progressed by use of the deep submicron of VLSI design rule. Systems on a chip (for short, SoCs), i.e., several functional cores being integrated in a single chip, have become the mainstream technology. On the other hand, A Network on a Chip (NoC), i.e., a communication-centric platform, offers an on-chip interconnection network. The NoC is one of the on-chip communication systems. The NoC is used in place of conventional shared bus systems. There are many NoC topologies for connecting cores to each other, such as Mesh, Ring, Spider on, and so on. To evaluate the NoC topologies, a simulation based approach was used for the modeling and analysis of the topologies. However, some properties of the topologies could affect the performance of the NoC systems. This paper describes about the performances of the topologies about the communication aspects by the simulation based approach. © 2014 IEEE.
