The validity of sensed data that labels the change events plays the most important role in the accuracy and reliability of the Internet of Things (IoT)-based Wireless sensor network (WSN) applications to assure data quality for perfect decision making. In this study, we suggested and implemented a sensor data validation approach based on adaptive threshold for real-time IOT/WSN sensor node level....
A Mobile Adhoc Network (MANET) is featured by multi hop wireless connectivity with topology change due to highly mobile stations with autonomous configuration ability. Therefore, it is very challenging to develop vibrant and resourceful routing Protocol for MANET which also performs excellent routig with security feasibility.

Due to the scaling of devices in nanometer regime speed and power related issues rises in digital circuits. Carbon nanotube field effect transistor (CNTFET) has been used in the present work as a low power circuit element. The major advantage of CNTFET is low power and energy consumption as compared to the conventional CMOS. This paper proposes the basic implementation of CNTFET inverter, MUX and...
Software Defined Networks provide the ability to manage networks from a centralised point through separating control plane from the data plane. This brings opportunities in terms of manageability, flexibility and cost savings in network operations. This centralisation, however, also brings about a potentially serious performance bottleneck and poses a scalability issue in high performance networks...
Distributed teams are geographically separated and may need to rely on networked communication technologies (e.g., audio or video conference, email) to mediate their interaction. A limitation of these networked communication technologies is that they generate transmission delays that result from network congestion or routing issues. For the purposes of this research we focus on verbal communication...
Microgrids gathered a lot of attention in the last decade and are believed to be the future power systems. The renewable energy sources can be easily integrated into the Microgrid. Renewable energy sources such as PV, wind and fuel cells are usually connected through voltage-source inverters in the Microgrid. In order to share the same loads, these inverters are connected in parallel and to achieve...
Random Linear Network Coding (RLNC) is a popular coding scheme to improve communication over lossy channels. For packet streaming applications (video streaming, general IP streams), recent research has shown that sliding window schemes can improve in-order delay properties compared to the block/-generation based coding. However, implementing sliding window RLNC with a limited coding window poses new...
Wireless Body Area Network (WBAN) is an excellent technology for chronic healthcare monitoring applications. In which, sensor nodes are connected wirelessly in, on or near the human body and also responsible for Data Collection, Data Processing and Data Transmission. Sensor nodes are generally powered by small batteries with sturdily restricted energy resources, so minimizing the energy consumption...
This paper presents the concept, traits, principle and structure of 64-bit high speed VLIW microprocessor. The microprocessor facilitates 16 kinds of operational function.

This paper concerns the Discrete time Sliding Mode Control (DSMC) of complex system with input delay, the synthesized control law will be tested on a four tank hydraulic system. A predictor in discrete time is introduced to convert the original system with input delay to an equivalent system without the explicit appearance of time delay and makes the control problem solvable. Simulation studies show...
This paper presents a novel method of selecting an optimal path between the nodes for data transmission in mobile ad hoc network. Mobile ad hoc network is a temporary, infrastructure-less network that communicates in multi-hop manner. Routing is an important issue in mobile ad hoc networks. Normally, routing protocol may selects the path between two nodes based on multiple metrics like distance between...
Traffic light control unit can be designed as a synchronous sequential machine with finite number of states. Explicit finite state model is used to design the necessary coding for control system using Verilog HDL. The machine is modelled with only six states and these states are chosen based on the traffic control algorithm. In each state necessary delay is provided and for that particular delay the...
Exploiting multi-user diversity (MUD) means to assign the resources to the user experiencing the best channel conditions. When multicast communication is considered, MUD means that a sender can serve the intended receiver users using one or many data transmission rates. In fact, MUD-based multicast schemes aiming to maximize the multicast throughput (e.g. DOMS and MOST) or to minimize the multicast...
To solve the key management related problems encountered in symmetric as well as asymmetric key based schemes, recently a public key based scheme known as Certificateless Effective Key Management protocol (CL-EKM) has been proposed for dynamic Wireless Sensor Networks (WSNs). In spite of showing numerous advantages over the previously proposed schemes, this protocol shows some critical limitations...
A new mathematical model that represents the coexistence between normal and leukemic populations of cells is proposed and analyzed.

In this paper we discuss about 3 general issues on mesh topology in “networks on chip” (NOC): Utilizing multi-level mesh for delay reduction, using route by considering the mesh topology concept, and finally an optimal model of mesh topology named “multi-level mesh topology” which is defined based on 5-layer network model is suggested. In multi-level mesh topology we can see that this architecture...
Management of overflows caused by stochastic traffic arrivals is one of most important consideration for traffic signal control of isolated intersection because overflows of one cycle can results in not only extra delay in following cycles but also blocking of upstream intersections. Although the stochastic arrivals problem has been studied either by simulation based methods or analytical models,...
FinFETs are the devices which replaced bulk MOSFETS because of its surpassing quality of minimizing leakage power and reducing short channel effects occurring in MOSFETS due to decrease in channel length.
