In delay sensitive applications of wireless sensor network, it is required to monitor the situation continuously with the sensors. The continuous monitoring operation results in more energy consumption of the sensor nodes. If the delay in data processing and it's communication from one node to other is more, then energy requirement may increase. In most of the situations, it is difficult to replace the battery of a sensor node, after the deployment of node in the network. The efficient energy management and low latency are the important issue in such applications as they affect the life of network. Many protocols are suggested by various researchers for energy efficient data process and minimum latency in sensor networks. There are limitations in existing protocols as they are particularly designed either for energy efficiency or minimum latency or for both. This paper presents the new protocol to overcome some of the existing protocol's limitations. In this paper, a concept of distance metric based routing protocol approach is explored, for 'high energy efficiency' and 'shortest path selection' for latency improvement. The proposed new protocol is 'Dynamic Energy Efficient Latency Improving Protocol (DEELIP)'. The simulation results are compared with 'AODV' routing protocol. It is observed that in proposed protocol; the overhead of the network traffic is reduced, resulting in improvement of energy efficiency and latency than existing routing protocols. © 2013 IEEE.

In real time wireless embedded devices such as sensor network, laptop, cell phones, etc. Where functionalities are increasing exponentially, so computational power also increases exponentially. So they need high-performance processors. To fulfill this demand multiprocessor architectures are coming into existence where parallel program can be execute with minimizing total execution time or makespan. Such multiprocessor architectures require efficient algorithms to schedule the parallel tasks that can minimize the makespan, as well as Power consumption. In this paper, we address the problem of scheduling Directed Acyclic Precedence Graph (DAPG) on multiprocessor architecture with the objective of minimizing the Energy related to IPC (E-IPC). We propose a new scheduling heuristic called as Energy Saving Dynamic Level Scheduling (ESDLS) which accounts for E-IPC consumption. This algorithm is based on well-known compile time Dynamic Level Scheduling (DLS) algorithm that accounts for IPC overhead while mapping DAPG on to homogeneous multiprocessor architecture. © 2015 IEEE.

Since RFID is wireless technology, it enables the identification from a distance, depending upon the read range of the tag. There is a vast requirement of RFID technology in security, military, health-care, airline, library, sports, farming and other applications, not only for identification but as a sensor to monitor different parameters related to these fields. RFID based environmental sensor can be designed with the integration of sensing material in a microstrip antenna. The properties of the sensing material are responsible for converting a passive tag as a sensor. Here, RFID based passive chemical vapor sensor is presented doped with the conducting polymer. A sensitive Polystyrene Sulfonate is used as sensing material to integrate in H-shaped slot of PIFA like tag. The designed tag working at 870 MHz is characterized by turn-on and back-scattered power measurements. The experimental results are also presented by considering known and unknown percentage of water vapor and the moisture levels. © 2012 IEEE.

In the present letter, a novel aqueous chemical method is employed to prepare thin film of Sm2S3 material containing porous network of interconnected nanoparticles for super-capacitive application. The orthorhombic phase formation of Sm2S3 film is concluded from X-ray diffraction study. The chemical states of samarium and sulfur are determined using X-ray photoelectron spectroscopy study. The pseudocapacitive behavior of Sm2S3 showed a maximum specific capacitance of 248 F g-1 in 1.5 M LiClO4 electrolyte prepared in propylene carbonate electrolyte. The nature of charge and discharge curves confirmed pseudocapacitive behavior of film electrode. The highest power and energy densities of 15.6 kWh kg-1 and 54.6 Wh kg-1, respectively are obtained. An electrochemical stability of 94% is retained after 1500 cycles. © 2015 Elsevier Ltd. All rights reserved.

The delay sensitive industrial control applications like Industrial process control, Environmental control, Gas leakage monitoring, etc. in this a reliable communication between sensor and base station are highly essential. Wireless Sensor Networks (WSN) becomes an immensely popular technology in such application as it offers low latency and high energy-efficiency in message transmission. Life span of the network can be extended by using appropriate energy efficient routing protocol. The three standard routing protocols, namely Ad-hoc On-Demand Distance Vector, Destination Sequence Distance Vector and Ad-hoc On-demand Multipath Distance Vector have been analyzed. In this work we have proposed multi-sink model to compare with conventional single sink model. We have designed probabilistic model to compare transmission delay in these two models. They are also compared with IEEE802.11 and IEEE802.15.4 MAC protocol. The proposed WSN model is analyzed by estimating end-to-end delay, energy consumption and packet drop ratio of both models. NS-2 simulator is used for result analysis in different traffic conditions. The Quality of Service can be improved by minimizing delay in packet delivery of the network. It has been observed that overall delay can be minimized significantly in proposed model. © 2012 IEEE.
