Wireless Communication is an inevitable part of Smart Home domain. A Mobile Ad-Hoc Network (MANET) is defined as an arrangement of wireless mobile nodes which creates a temporary network for the communication. MANET suffers from both kinds of attacks, active and passive attacks at all the layers of the network model. The lacks of security measures of routing protocols allow attackers to intrude the network. Wormhole, the attack is generated by tunnels creation and it results in complete disruption of routing paths on MANET. The proposed security approach is to detect and mitigate wormhole attack. It is secured Ad hoc on demand distance vector (AODV) approach which efficiently finds wormhole attack present in a MANET and Digital signature is used to prevent it. This approach is based on a calculation of tunneling time taken by tunnel to analyze the behavior of wormhole. Afterward, it decides some static threshold value. Based upon this tunneling time and threshold value, it decides whether given node is wormhole node or trustworthy node. A digital signature and hash chain algorithm is applied to mitigate the wormhole node.

In recent years, E-commerce had made a tremendous impact on the world. However before the emergence of E-commerce, individuals can't skim the information about the products within short time of the period, so therefore recommendation system was introduced. The principle point of the recommendation system is to prescribe the most appropriate items to the user. Many of the recommendation systems mainly use content based method, collaborative filtering method, demographic based method and hybrid method. In this paper, the major challenges such as “data sparsity” and “cold start problem” are addressed. To overcome these challenges, we propose a new methodology by combining the clustering algorithm with Eclat Algorithm for better rules generation. Firstly we cluster the rating matrix based on the user similarity. Then we convert the clustered data into Boolean data and applying Eclat Algorithm on Boolean data efficient rules generation takes place. At last based on rules generation recommendation takes place. Our experiments shows that approach not only decrease the sparsity level but also increase the accuracy of a system.

A taste sensor using a lipid/polymer membrane, i.e., an electronic tongue with global selectivity, has been developed for objective evaluation of the taste of foods and beverages. Moreover, the taste sensor has been also contributing to safety of foods, e.g., the sensor membrane with strong hydrophobicity was used to detect sodium dodecyl sulfate (SDS), a negatively charged surfactant, which was generally added into the pesticide because of its strongly melting effect. An immersion process in monosodium glutamate (MSG) solution, called “MSG preconditioning” was needed to obtain the change in membrane electric potential caused by adsorption (CPA) for sensor membrane before measurement. However, what happened to sensor membrane during MSG preconditioning is unclear. In this paper, we examined the relationship between the CPA value and the period of MSG preconditioning. The amount of adsorbed SDS and MSG was measured to figure out whether the CPA value is related to the amount of adsorption. As a result, with the precondition process progressed, the CPA values showed concentration dependence on SDS concentration, and increased to a peak by preconditioning for one day then decreased to a stable state after that. The amount of adsorbed SDS depended on the SDS concentration but did not change with the increasing of preconditioning time. In conclusion, we revealed that the most suitable time of MSG preconditioning for the membrane for SDS was one day. The CPA value was affected by both the surface charge density and the amount of absorption.

New photo Thin-Film Transistor able to detect light in red and near-infrared wavelength range with high detectivity and high speed, is developed. Detectivity of 1013 Jones at 850 nm is obtained. The rise time and the fall time of the answer to pulsed light are 46 ms and 10 ms respectively. Responsivity value is 1700 A/W at 760 nm and 13 A/W at 1.3μm. The photo-transistor is based on the light absorption by PbS quantum-dots that are embedded in an epoxy based (SU8 photoresist) thin-film matrix. This thin-film acts as the gate insulator of the transistor and it replaces the usual silicon dioxide gate insulator. The TFT's fabrication is made through a usual top-gate LTPS-TFT process only replacing the top-gate insulator by the mixed QDs-SU8 film. Present TFTs can be easily integrated in any Large-Area electronics process.

Touch function is merged into the display for the convenient interfaces between man and machine, particularly in mobile phones. In addition, the fingerprint recognition module is also adopted in mobile phones for the security purpose. In this paper, capacitive sensor arrays of oxide thin film transistors (TFTs) were investigated for fingerprint recognition. For the transparent sensor array, oxide TFT was used and also the transparent indium thin oxide (ITO) electrodes was investigated for 450 × 450 pixel arrays. The simulation results of the sensor array of oxide TFT show that ITO can be used in capacitive pixel sensor arrays to achieve its transparency. The electrode area dependence on the sensing signal was investigated for the various glass thicknesses. The rather thick glass gives much reduced sensing signal and the allowed thickness was lower than 8 μm, therefore, for the high sensing signals the coating material with enough hardness is necessary for the replacement of the cover glass.

Compared with the infrared focal plane array (IRFPA) based on amorphous silicon (α-Si), IRFPA based on vanadium oxide (VOx) has the advantages of big temperature coefficient, low noise and so on. Therefore, it is believed that VOx IRFPA has important application in both military and civil field. In this paper, the designs of driving module and signal processing module of VOx IRFPA are proposed.

During recent years, with the rapid development of wireless sensor technologies, Wireless Sensor Network (WSN) systems are widely used in various applications, such as environmental monitoring, smart home and so on. A WSN system is a self-configuring network of sensor nodes connected by wireless links. The union of sensor nodes forms an arbitrary topology. Routing in a WSN system is a critical task. Therefore, the routing protocol has much effect on the throughout performance and energy consumption of the whole network. Most available routing protocols employ distributed structure that is complex and has high energy consumption. Compared with these distributed protocols, a novel centralized routing protocol with a central node is proposed. And all kinds of routing management of the whole WSN systems are centralized in the central node. The centralized management strategy reduces routing overhead and energy consumption of the whole network. Finally, a WSN system with Raspberry Pi and OpenWrt is designed to evaluate the new method. Experiment results show that it is very efficient.

This work implements an FPGA (Field Programmable Gate Array) based reconfigurable IPSec ESP core. The IPSec protocol, developed by the IETF (Internet Engineering Task Force) in 1998, is a popular solution to facilitate protection of the data being transferred at the IP layer. IPSec ESP is one of the two main IPSec protocols (AH: Authentication Header and ESP: Encapsulation Security Payload). IPSec ESP is used to provide data confidentiality security services with Authenticity (optional). Implementation of the IPSec is a computing intensive work, that's why hardware implementation of IPSec is a best solution. Here, to design IPSec ESP core an encryption algorithm AES is used. Proposed design also supports ESP-tunnel and ESP-transport mode of operation. This core is tested by applying default length of 576 bytes for an IPv4 datagram and results are reported on Virtex-5 and Virtex-6 FPGAs. The proposed IPSec ESP core can be used to provide data confidentiality security to IoT applications.

Wayside acoustic monitoring technique is promising for health monitoring of wheel-bearing for railway vehicles. However, due to the high relative moving speed between the railway vehicle and the wayside mounted microphones, the recorded signal is embedded with Doppler Effect. What's more, the background noise is relatively heavy which makes it difficult to extract the diagnosis relevant information. To solve these problems, this paper introduced a railway wheel-bearing wayside acoustic fault diagnosis scheme based on Doppler Effect reduction and Ensemble Empirical Mode Decomposition (EEMD). Firstly, an improved Doppler Effect reduction method is introduced incorporating with the kinematic parameters estimation and signal re-sampling method. Secondly, the EEMD is employed to extract the diagnosis relevant Intrinsic Mode Function (IMF). Finally, the envelope spectrum analysis is employed to identify the local fault. The effectiveness of the proposed method is verified by experimental cases analysis.
