“…The black, white, and crossed circles represent the active sensors, inactive sensors, and the sink respectively. As shown in the figure, if 0 ≤ t ≤ 40, each algorithm has a specific error interval (in %) as follows: [14,20] for SVM, [7,10] for NB, [7,12] for RF, [2,6] for GTB, [4,8] for TBFS, and [12,17] for NN. After that (if t > 40) the error rate for each algorithm increased significantly at these intervals to reach, at t = 50, 40 % for SVM, 20 % for NB, 16 % for RF, 30 % for GTB, 18 % for TBFS, and 36 % for NN.…”

“…WSN strategies that can be considered are: the topologies [41,73,40], coverage [25,30], deployment strategy [52,17], scheduling mechanism [71,30,63,64,31], density [3], security [51,4], data aggregation [37,75,44], packet transfer distance, battery, memory, etc. These strategies have a strong impact on the effectiveness of the network with time, consequently on the quality of the data that will be captured in the monitored area, and finally on PHM.…”

In this article, we used Wireless Sensor Network (WSN) techniques for monitoring an area under consideration, in order to diagnose its state in real time. What differentiates this type of network from the traditional computer ones is that it is composed by a large number of sensor nodes having very limited and almost nonrenewable energy. A key issue in designing such networks is energy conservation because once a sensor depletes its resources, it will be dropped from the network. This will lead to coverage hole and incomplete data arriving to the sink. Therefore, preserving the energy held by the nodes so that the network keeps running for as long as possible is a very important concern. If we achieve to improve the network lifetime and Quality of Service (QoS). Diagnosing the state of area will be more accurate for a longer time. One of the most important elements to achieve a QoS in WSN is the network coverage which is usually interpreted as how well the network can observe a given area. Obviously, if the coverage decreases over time, the diagnosis quality decreases accordingly. Various coverage strategies are thus proposed by the WSN community, in order to guarantee a certain coverage rate as long as possible, to reach a certain QoS that in turn will impact the diagnosis and prognostic quality. Various other strategies are in common use in WSN like data aggregation and scheduling, to preserve a QoS in wireless sensor networks, as long as possible. We argue that such strategies are not neutral if this network is used for prognostic and health management. Some politics may have a positive impact while other ones may blur the sensed data, like data aggregation or redundancy suppression, leading to erroneous diagnostics and/or prognostics. In this work, we will show and measure the impact of each WSN strategy on the resulting estimation of diagnostics. We emphasized several issues and studied various parameters related to these strategies that have a very important impact on the network, and therefore on data diagnostics over time. To reach this goal, to evaluate both prognostic and health management with the WSN strategies, we have used six diagnostic algorithms.

Certain Wireless sensor network (WSN) applications such as military and e-health care require the inter-node communication to be secure. The tiny WSN nodes have limited computational power, memory and finite energy source. These constraints restrict the implementation of highly secure models on the devices as they demand more memory and involve compute intensive operations. Several protocols have been designed for providing different security levels with varying strengths at the expense of the amount of hardware and computational power of the processor in the WSN node. In wireless equivalent privacy (WEP) model static keys are generated for the XOR operation with the plain text in the encryption process. This work proposes a new security model that provides dynamic keys to the encryption/decryption stages. A model for the proposed scheme has been developed using nesC and the same has been implemented on a IRIS WSN node. The WSN implementation of the proposed security model has been compared with those of WEP, WiFi Protected access (WPA) based on memory usage and execution time.

Wireless sensor network plays a significant role in the construction of smart cities, and the social network includes the Internet of Things, etc. In general, networks are most vulnerable of all the wireless devices due to the massive damage caused by disrupting these networks. Hence the nodes present in the network should get validated for its reputation. Therefore a Long and Strong Security mechanism with two-level checks is proposed here. Level 1 check includes verifying node reputation value and level 2 check includes Elliptical curve cryptography (ECC). Each sensor node sends the public master key to the cloud and secretly stored in the sensor node. Before data transmission, every node checks the master key, and if the master key is a match, then it transmits the data to the next hop. This process is continued until the source reaches the destination in the network.1. Introduction. Many ways are available for implementing security measures, and among them, the most commonly used technique is cryptography. The cryptographic methods usually have three operations to be carried out for providing security. The activities include conversion of simple passage to cipher (secret code) text, identifying the value of secret key used and processing the algorithm of an understandable or straightforward transcript [17].From the key variations, bi-cryptosystem are generated, namely symmetric key cryptosystem (private) and asymmetric key cryptosystem (public). If a similar key is used for both decrypting and encrypting the text or communication, then it is said to symmetric key cryptosystem. If a pair of keys such as private and public key utilized for decrypting and encrypting process, then this process is said to be asymmetric key cryptosystem. There were several scheme and algorithms projected to public-key cryptography as its initiation. Some example techniques for public-key cryptography are Diffie Hellman, Secured hash algorithm, RSA, ECC, etc. Prime numbers are used to generate keys for securely transferring data [2]. The public key is utilized for encrypting simple transcript or to confirm a digital mark, and the private key is utilized for decrypting secret code transcript or to generate a digital mark. Prime based ECC key generation is implemented for providing security measures and Further sections of this paper are organized in the following way. Section 2 gives a detailed description of existing security algorithms. CC based Secure Data Encryption scheme analysis is explained in detail. In section 4 the results are analyzed based on the presentation projected and conventional systems. In the final section, the conclusion of the work is included with the applications. Related Works.Most of the works have been carried out for providing security in the field of wireless communication using symmetric and asymmetric key cryptosystems. The security issues are reduced in maximum by using the existing security mechanisms. Some of the secured mechanisms are discussed here in detail as follows;The packets are forwarded t...
