An Enhanced Delay Sensitive Data Packet Scheduling Algorithm to Maximizing the Network Lifetime

Abstract: The objective of the packet scheduling algorithm is to avoid the delay and drop rate in the wireless network. At the same time, without proper scheduling it may lead to high collision, delay and drop rate. This can be overcome by a proposed Enhanced Delay Sensitive Data Packet scheduling (EDSP) algorithm. This algorithm mainly focus on reduction of the delay and increase in the network lifetime and energy efficiency. This proposed EDSP algorithm follows three rules for proper scheduling such as medium selection, weight calculation and priority scheduling. After assigning the source and destination node, by using the AODV routing protocol shortest path with lesser number of relay nodes will be found. Then the source node data flows will be stored in the queue, when the queue size starts to increase, a particular threshold rate scheduling is required. Scheduling checks the channel medium, based on the busy or idle state, node may be sleep or awake state respectively. If the state is busy, all the data flows will be stored in the buffer. If the state is idle, buffered data will move to queue and then forward based high weighted data as first priority. Simulation results have analyzed the performance of the proposed algorithm in two different stages by varying the queue size of 50 and 100 cm. The proposed algorithm has increased the network lifetime and energy efficiency and decreased the delay and drop rate.

Automation in unmanned railway level crossing

Abstract: This paper deals mainly with the automation in unmanned and manned railway crossings. In recent days the accidents in railway level crossing are increasing. There are two types of level crossing Manned and Unmanned. The accidents occurring in both level crossings are very severe. Our work uses simple mechanical and electrical components to control the railway gate. The Infrared detector which is placed at a few distances away from the gate detects the train and sends the signal to the controller. From the controller the signal is send to the timer which is connected to LED display near the gate. Timer displays the time remaining for closing or opening of the gate according to the necessary situation. The power is transmitted from the controller to the motor which is connected to the L-shaped cylinder through the pinion of rack and pinion arrangement. This rotary motion of the pinion produces the linear motion of the rack. This linear motion of the rack actuates the horizontal and vertical piston one by one of the L cylinder which in turn opens or closes the gate. Thus our paper presents a highly secured and safe automated level crossing at low cost, which requires no human monitoring.

Implementation of virtual fitting room using image processing

Abstract: There has been a great increase in interests towards online shopping. In case of purchase of products like apparels which always require a sense of knowledge on how cloths would fit upon a person. This is the major reason why less number of apparels are being shopped online. Hence, a virtual dressing room which would make people know how cloths personally fits in would be a great luxury for the online sellers which could give a wide choice for customers. For online marketers, this would be a great tool for enhancing its market.

Progressions in chemical and biological analytes sensing technology based on nanostructured materials: A comprehensive review

Abstract: In general, nanoscience technology can be best described as a medium of design, fabrication, and application of nanostructured materials, as well as a fundamental understanding of physicochemical properties and phenomena of nanomaterials and nanostructures. Owing to the fact they offer a plethora of perspectives for modern living and fascinating technological advancements, sensors that are based on different types of nanostructured materials have uplifted the technology to greater heights of late. Nanostructure-based sensors can detect biologically as well as environmentally pertinent target species with high exactitude. The recognition of the targeted species, which usually befalls through a controlled binding affair, is then communicated as a readable signal. In addition, the surface-functionalized nanostructured materials, comprising both inorganic and organic components, have recently been inspected as potential platforms for sensing applications and have huge advantages over other materials. In this extensive tutorial review, we have focused on the current development of functionalized and non-functionalized nanostructured materials that can be used in environmental and biological applications, in which these chromofluorogenic chemosensors can selectively and sensitively detect specific analytes of interest through different principles and mechanisms. Additionally, few pieces of literature on the fabrication of nanostructured materials-based sensor devices are also listed out.
