Requirement for high bandwidth internet traffic is growing rapidly now-a-days. Utilization of the available resources becomes troublesome due to rise in the number of users. So it is important to provide the resources efficiently. To solve the problem of resource provisioning, many developments have been made by the researchers. During working hours, the scheduled traffic is huge and sluggish during...
Requirement for high bandwidth traffic has been increasing very rapidly. Efficient and effective provisioning of resources is very important now-a-days. Due to the increase in number of users, providing sufficient bandwidth has become a difficult task for the service providers and network operators. Researchers have developed many techniques to resolve this issue but they have not reached to full...
The drastic growth in internet services has led to growth in data sharing between the users. This has led to need for powerful and large data centers, where huge number of storage and computing servers are interconnected. According to the reports, annual data center traffic is growing at a very high growth rate of 25%, of which the major contribution is due to the servers within the data centers,...
The requirement of earlier identification of weed growth and plant disease is one of the most important procedures in precision agriculture. In this research work we identified the best method of positioning the optical sensors to get the best possible images. To address this purpose the variant of SVD is used for feature construction. Our proposed approach optimize and reiterate our similar earlier...
Plant monitoring is being done under precession agriculture now a days using areal sensors the segmentation of plant and decease symptoms in leaf image can be a valuable and timely aid for controlling the disasters early. In this research digital image of different plants along with leaf and other components have been segmented and quantified using simple techniques like SVD, modified methods on SVD...
In this paper, a health care system is described for rural areas considering a small village using hybrid network i.e. which operates both in ADHOC and cellular region. In this system, a small village is considered in which sensors are attached to people, the whole area is divided into clusters. The sensors considered for this system can operate in both ADHOC and GSM region. In each cluster, a sensor...
In this paper, an efficient routing protocol for patient monitoring system in rural areas was proposed using wireless sensor network (WSN) so that the patients can be treated within less time. In this system, a village with GSM network is considered and the people in that village are continuously monitored using AMON sensor, an advanced medical monitoring and alert system. All the AMON's work in ADHOC...
Oata Grid provides transparent access to grid user. The grid data stored across distributed storage resources whilst fulfilling the Confidentiality, Integrity, Availability (C,I,A). The stored data is replicated in data grid to increase the availability. Replica Manager uses replica replacement algorithm to decide which replica to be replaced for the new replica when there is not enough space for...
Oata replication in data grid increases the availability of data and reduces the total execution time of the grid job. Replica replacement algorithm plays a vital role when storage space is limited. This algorithm decides which replica to be replaced for the new one. The binomial prediction, Least Frequently Used (LFU), Least Recently Used (LRU) replica replacement algorithms are well known in the...
To provide effective communication among the mobile users, interference has to be reduced to maximum extent. Reducing the interference plays a major role in providing effective communication among mobile users. By using smart antennas we can increase the capacity and coverage area of wireless sensor networks. By increasing the capacity and coverage area it is possible to provide line of sight communication...
The paper describes an Energy — Efficient Resource Allocation protocol for Wavelength-Routed All-Optical WDM Networks. Protocol selects efficient and low power consumption optimal primary and backup paths. The path selection will be done by Central Management System (CMS). The selection will be by two methods, i.e., the path with less number of free wavelengths will not be considered for selection...
In this paper, we present the characterization of the Ring oscillator for submicron technology in terms of the first order design equations of the MOSFETs, and we arrive at the extent upto which the short channel effects influence the oscillating frequency. In addition, a solution is suggested to reduce the duration of metastability upto 50%. The Ring oscillator is designed from 3-stage till 15-stage,...
In this work, an efficient channel utilization scheme based on the Distributed Dynamic Channel Assignment (DDCA) is proposed. It can handle three types of constraints Adjacent Channel Constraint (ACC), Co-Channel Constraint (CCC), Co- Site Constraint (CSC) simultaneously while assigning the channel. Previous methods like Dynamic Channel Selection and Reassignment (DCSR) scheme employs reassignment...
Ad Hoc wireless network is a type of wirelessnetwork, in which there is no any fixed infrastructure. Devices in Ad Hoc network can move around thenetwork within a given range. Currently most of thetransactions are performed through the computernetworks so they are more susceptible to many physicalsecurity threats. One of the major DOS Attacks thatdegrade the performance of the whole MANET is BlackHole...
Network-on-Chip (NoC) architecture in recent years has been considered as the overwhelming communication solution to provide scalability in multi core systems over traditional bus-based communication architecture. There is an increased use of multi-core with NoC in embedded systems solutions. Energy efficiency in the Network-on-Chip (NoC) is one of the key challenges as these embedded systems are...
Unmanned Aerial Vehicles (UAVs) or Unmanned Aerial Systems (UASs), known for their easy maneuvering, greater flexibility and low costs, are promised to be an excellent aerial sensor for transportation applications. It could be an effective airborne surveillance system for rapid deployment with low cost. UAVs are very flexible and fast compared to the normal road traffic monitoring techniques. In addition,...
This work proposes two different methods for polarity detection in speech and Electroglottograph (EGG) signals using Hilbert Envelope (HE). HE is defined as the magnitude of complex time function and hence an unipolar signal. The zero frequency filtering (ZFF) obtained from HE of LP residual is of same phase for both polarity. Alternatively, the ZFF of speech and EGG, integrated linear prediction...
Capacitive pressure sensors can be used for touch mode applications with pressure ranging from 0.05 MPa to 2 MPa. This paper provides the information about the variation in dynamic range of a MEMS capacitive pressure sensor when its sensitivity is improved. The shape of the capacitive pressure sensor diaphragm is changed from normal flat diaphragm to a centre bossed structure and was found that Bossed...
In cellular networks Device to Device (D2D) communication is used to improve the resource utilization and the throughput. SNR Based Master-Slave Dynamic D2D Communication Algorithm (SMSDCA) is proposed to improve the resource utilization of the cellular network and improved Quality of Service (QoS). It is achieved by allocating some User Equipment (UE) as master in that cluster based on SNR and energy,...
In this paper a simple method is proposed using zero frequency filtering (ZFF) of a close approximate glottal flow derivative (GFD) to extract glottal closure (GCI's) and opening instants (GOI's) from speech. The GFD is obtained from iterative adaptive inverse filtering (IAIF) which contains such instants. It is observed that GCI's can be located by positive zero crossings of zero frequency filtered...
