Wireless sensor network plays major role in military surveillance, nuclear power plants, and forest fire detection. Many routing techniques and cryptographic methods were applied to secure the network, which proved inefficient in practice. Data is transmitted from source to destination either by single hop or multihop routing. In this paper the threats that are encountered while using multi hop routing in WSN is discussed. The attacks were mainly due to the identity of nodes a this paper deals majorly with sink hole attack, wormhole and Sybil attacks. To overcome these attacks due to deception, a protocol named TARF, trust aware routing protocol framework is implemented. It is considered to be an energy efficient and trust worthy protocol. The resilience of this protocol is evaluated through empirical experiments and simulations on large WSN under various network conditions. TARF produces less overhead in the network.TARF proves to be more effective in securing network by identifying the malicious nodes and by preventing it to be used while transmission of data.

The current healthcare systems, structured for reacting to crisis and managing illness are facing new challenges. Traditionally, healthcare services are provided by using wired networks such as telephones, and DSL or cable-modem-based broadband access systems to transmit biomedical data between a hospital and the point of care. However, these fixed systems have limitations in providing services to patients in remote localities and when the patients are mobile. Therefore, mobile healthcare services with applications in emergency healthcare have become popular to provide prompt and effective patient care. Wireless transmission of medical signals has high error rates. The bio –medical signals, where every second of data could mean abnormal patterns, cannot tolerate such losses. One of the solutions to overcome such losses Compressed Sensing (CS), an emerging signal processing technique that is used to recover the losses that occurs in the healthcare networks. CS enables the reconstruction of the signals if any data are omitted at the sender or dropped by the communication channel. Computer simulation results demonstrate that the proposed scheme may serve as an efficient procedure to recover the data loss that occurs in mobile health care applications.Keywords

With an increasingly mobile society and the worldwide deployment of mobile and wireless networks, wireless infrastructure can support many current and emerging healthcare applications. The mobile healthcare systems has many advantages such as faster searching and availability of relevant information, efficient decision-making and quicker documentation by physicians and medical staff. Patients can remain under constant observation of expert physicians without being physically present at the hospitals. In spite of several advantages there are some significant challenges in the implementation of mobile healthcare applications. One of these challenges is the high error rates (data loss) that occur due to wireless transmission of medical signals. Such losses are intolerable in the transmission of bio-medical signals. One of the solutions to overcome such losses will be destination side loss recovery schemes. Computer simulation results demonstrate that the proposed scheme may serve as an efficient filtering procedure to recover the data loss that occurs in mobile health care applications.

The present investigation was carried out during 2016-2017 to identify the seed development maturation studies in Barnyard millet cv. MDU 1. The results revealed that seeds attained physiological maturity on 50 days after anthesis as evidenced by the maximum panicle length (30.7 cm), fresh weight (31.2 g), dry weight (23.5g), fresh weight of the seeds (23.4g) and dry weight of the seeds (14.5g). The change of colour of panicle and seed from green to dark brown could be considered as a visible index of maturity. The seed quality parameters viz., germination (51 %), shoot length (9.59 cm), ischolar_main length (18.5 cm) and dry matter (0.025 g/10 seedlings) and vigour index (1175) were also maximum at 50 days after anthesis.Keywords

In this paper, an effort has been taken to develop an algorithm for solving Intuitionistic Fuzzy Direct Insignificant Programming Problem (IFLFPP). Here, the cost coefficients in the objective function of IFLFPP are taken as Symmetric Triangular Intuitionistic Fuzzy Numbers (STriIFNs). The problem has been solved in the crisp environment by using direct ranking function. A numerical example is given to illustrate the importance of the proposed method.

Employment opportunities are scramming from the reach of Indian engineering graduates due to their inadequate skills set. This evinces the skills gap prevailing between the workplace preparedness of the students of engineering and the exigencies of global workforce. 21st Century Skills are the competencies required from the students of present era to succeed in their life and career, in the absence of which the students encounter major employment deficit. Although, studies have been conducted on the need for 21st Century skills and on training teachers to instigate students' skills set, the inevitable focus on students' perception towards their need for career prospects has been left unexplored. Hence, the paper prospects the preparedness and potential of the students of engineering with respect to Learning and Innovation Skills and Life and Career Skills of 21st Century Skills. An online survey with self-rating questionnaire has been administered using random sampling technique among 111 final year students of Mookambigai College of Engineering and Dhanalakshmi Srinivasan Engineering College, Tamil Nadu, between December 2018 and January 2019. Descriptive analysis, and parametric tests have been computed to investigate the data using SPSS. The findings have indicated the dearth of students' skills set in employing 21st Century skills set. The results imply the desideratum of enhancing the students' skills set that the study eventually recommends the integration of 21st Century skills set in English classroom of engineering and technology to meet the demands of the workplace.Keywords
