Abstract In this paper, we’re compared network protocol which is network lifetime longer when using LEACH Protocol, SEP, and TEEN in a heterogeneous Wireless Sensor Network with a Large Sensor Area. Also, we propose a method of divided layer the wide-area sensor filed and transmitting a multi-hop to improve the network lifetime. And we’re compared network protocol which is network lifetime more improved apply the proposed method to LEACH Protocol, SEP, and TEEN. We tried to compare results, TEEN showed the best network lifetime. Apply the proposed method to divided the sensor field, L-TEEN (Layered TEEN)’s network lifetime rates of improvement is highest. Keywords: WSN, BSN, WBAN, LEACH, SEP, TEEN, L-LEACH, L-SEP, L-TEEN 1. Introduction Wireless Sensor Network [1, 2, 6] is a network of Sensor Nodes which are consisting of Wireless. One of those utilizing wireless sensor network is a BSN. There are Homogeneous Network and Heterogeneous Network of the Wireless Sensor Network Type. Homogeneous Network is the same amount of energy of all nodes. Heterogeneous Network is nodes have different amounts of energy. According to the characteristics of the Wireless Sensor Network, it has been focused the study of the network lifetime. Various Protocols have been proposed to solve the problem of the network lifetime. It is to take advantage of the Wireless Sensor Network Protocol can improve the energy efficiency during the communication between the wireless device configured BSN. The typical protocol is LEACH Protocol, and continuously to improve and extend the LEACH Protocol. In addition, SEP and TEEN is proposed based on the concept of LEACH Protocol. LEACH Protocol is equally the energy consumption of sensor nodes selected by the Cluster Head random method. But LEACH Protocol does not guarantee to create ideal cluster. SEP is basically a Heterogeneous Network based Protocol and operations similar to LEACH Protocol, but the Normal Node and Advanced Node gives the threshold formula with a different Weighting factor. TEEN also operations similar to

With the advent of big data, data mining is more increasingly utilized in various decision-making fields by extracting hidden and meaningful information from large amounts of data. Even as exponential increase of the request of unrevealing the hidden meaning behind data, it becomes more and more important to decide to select which data mining algorithm and how to use it. There are several mainly used data mining algorithms in biology and clinics highlighted; Logistic regression, Neural networks, Supportvector machine, and variety of statistical techniques. In this paper it is attempted to compare the classification performance of an exemplary algorithm J48 and REPTree of ML algorithms. It is confirmed that more accurate classification algorithm is provided by the performance comparison results. More accurate prediction is possible with the algorithm for the goal of experiment.

Thus, vast enhancement has been made in- exchanging of information over transmission media, this should be beneficial in various disciplines of modern client/server applications but at other side, several massive vulnerabilities have been directly/in-directly associated with them. To resolve the security issues, a security mechanism is proposed which hide the sensitive information of images before transmitting to networks. Random size image samples have used and encrypted to protect them from unauthorized entities. The encryption mechanism manipulates the sample images, and corresponding secret codes are generated which help to protect the images from adversaries. To provide an indestructible security mechanism, cryptography algorithms are deployed and considered as best solutions to keep the secret information of images.

Networked Control System (NCS) has evolved in the past decade through the advances in communication technology. The problems involved in NCS are broadly classified into two categories namely network issues due to network and control performance due to system network. The network problems are related to bandwidth allocation, scheduling and network security, and the control problems deal with stability analysis and delay compensation. Various delays with variable length occur due to sharing a common network medium. Though most delays are very less and mostly neglected, the network induced delay is significant. It occurs when sensors, actuators, and controllers exchange data packet across the communication network. Networked induced delay arises from sensor to controller and controller to actuator. This paper presents an adaptive delay compensation process for efficient control. Though Smith predictor has been commonly used as dead time compensators, it is not adaptive to match with the stochastic behavior of network characteristics. Time delay adaptive compensation gives an effective control to solve dead time, and creates a virtual environment using the plant model and computed delay which is used to compensate the effect of delay. This approach is simulated using TrueTime simulator that is a Matlab Simulink based simulator facilitates co-simulation of controller task execution in real-time kernels, network transmissions and continuous plant dynamics for NCS. The simulation result is analyzed, and it is confirmed that this control provides good performance.
