Abstract: This Wireless Sensor Network (WSN) is gathering sensor hubs. A huge number of sensor hubs associated with each frame sensor arrange. Sensor hubs ordinarily comprise of radio handset, microcontroller and it is fueled with battery. In this Mobile Environment, the clients are furnished with Personal Digital Assistants (PDA) or advanced cells that can converse with the Sensors effectively. At the point when crisis happens, the WSN gives essential data to clients, So that guided to move out of an unsafe zone through connection with sensors. Remote system sensor joined with a route calculation could encourage securely control individuals to a building exit while helping them evade perilous range. We propose a plain route calculation for crisis circumstance. Clog Adaptive and little extend crisis Navigation calculation with WSNs (CANS) use level set strategy to track the development of the exit and the limit of the perilous territory, so that individuals close-by the risky region accomplish a gentle blockage at the cost of a slight reroute, while individuals inaccessible from the threat evade superfluous alternate routes. Firstly, the route of people looks for a safe-basic way, other than parcel misfortune or vitality productivity which is the primary need as in bundle directing. Besides, human route expends a great deal additional time than customary parcel directing procedure, because of the constrained development speed of individuals. Also, which are basic for a quick clearing, as they primarily concentrate on finding the briefest/most secure way for every individual, while other problematic (yet sheltered) ways are left unused all through a large portion of the departure procedure.

Abstract: In the recent years Visible Light Communication (VLC) has gained great interest due to the rapid developments in Light Emitting Diodes (LEDs) fabrication. Efficiency, durability and long life span of LEDs make them a promising residential lighting equipment as well as an alternative cheap and fast data transfer equipment. The advantages of indoor VLC that is offering illumination and data transmission simultaneously using the existing infrastructure, White LED lamp used as source. The significant challenge is a right location of the source allowed users to receive fine illumination as well as high data rate. In this paper we proposed a numerous distribution patterns with different number of LEDs to increase the signal to noise ratio (SNR) and enhanced the uniformity of the illumination. The indoor VLC system is modeled using the proposed pattern and the theoretical analysis is presented. Firstly we compare the normal distribution of the luminous intensity of one locations LED located on the center of room ceiling with our four locations LEDs model. To eliminate spot lighting 8 lactation of LED lamps was proposed. Lastly our novel arrangement using 17 locations has been investigated. A proposed design provide normal distribution which enhance the lighting and communication in whole room. A mathematical model of illumination LEDs has been studied, as well as the basic parameters which are important for the development of the design.

Abstract: In order to improve the quality of network monitoring, the monitoring design of the multi-motor synchronization control system based on IOT was present. In the paper IOT technology was adopted. The server part was completed on PC. And the client system was implemented on Android smart phone platform. And the motor control parameters were saved in text mode. Various parameters of multi motor synchronous system were monitored in text and graphics on Android smart phone. The parameter changes of the master motor speed and the tension were monitored on-line and shown in data curve mode. Users could browse in real time by mobile phone. Users could use manual / automatic two control methods to implement real-time control on the system. The communication parameters were stored in SQLite database. Socket network communication based on message notification was used in the system. More and more experiments showed that: The monitoring system was cost-effective, and good real-time performance. And the same time the system was quickly, low demand on the network, and easy to use.

Abstract: Pattern Division Multiple Access (PDMA) is a novel non-orthogonal multiple access scheme proposed to meet up the diverse demands on high capacity and large number of connections in the fifth generation (5G) wireless networks. PDMA uses the characteristic pattern to define the sparse mapping from data to a group of resources, and the sparsity of the pattern gives impacts on the capacity performance and detection complexity. The present thesis emphasizes greatly to develop a simulation model for the 5G compatible downlink Pattern Division Multiple Access (PDMA) scheme implemented wireless communication system. The simulated system incorporates a modern channel coding ((3, 2) SPC) and different low order digital modulation (4-QAM, QPSK and DQPSK) schemes. With implementation of G [2,3] PDMA pattern matrix for three users and considering total transmitted power of 40 Watt, 50%, 30% and 20% of total transmitted power have been assigned to first, second and third users and additionally phase shifting factors have been applied in power scaled transmitted signals of second and third users to resolve ambiguity in individual data separation. On consideration of both synthetically generated binary data stream and color image transmission in AWGN and Rayleigh fading channel, it is observable from MATLAB based simulation study that the ((3, 2) SPC) channel encoded simulated system is very much robust and effective in retrieving transmitted data. The impact of applicability of 2-D median image filtering technique in processing of three different identically sized color images and enhancement of image quality has clearly been observed. This thesis elucidates the benefits of multi-user data transmission in power domain.
