In wireless sensor networks (WSNs), secret shared keys must be established with the neighboring nodes in order to achieve secure communication. The challenge issues for secured communication in WSN are the Key management. Location Dependent Key (LDK) management is a suitable scheme when compared to other location based key management schemes because of lesser memory space requirement and lesser number of keys to be stored on each sensor node. However, the LDK is affected by communication interference problem which is solved by the key is distributed based on trust model. The distributed key updates and revocation processes are effectively resist inside attackers. An energy-efficient Key Management with Trust Model (KM-TM) for WSNs is proposed to achieve the secured communication and the nodes are resisting from the attackers. The performances of proposed KM-TM for WSNs are evaluated in terms of trustworthiness of sensor nodes and security breaches more effectively. © 2016 Institute of Advanced Engineering and Science.

The machine learning approach to fault diagnosis consists of a chain of activities such as data acquisition, feature extraction, feature selection and classification. Each one is equally important in fault diagnosis. As machine learning is a soft science, there is a lot of scope for finding mathematical reasoning which otherwise researchers do it arbitrarily or heuristically. Minimum number of samples required to separate faulty conditions, with statistical stability is one such important factor. This paper provides a method for determination of minimum sample size using power analysis. A typical bearing fault diagnosis problem is taken as a case for illustration and the results are compared with that of entropy-based algorithm (J48) for determining minimum sample size. The results will serve as a guideline for researchers working in fault diagnosis area to choose appropriate sample size. © 2010 Elsevier Ltd. All rights reserved.

A mobile ad hoc network is a collection of mobile nodes which are able to organise by themselves. In MANET a mobile station (MS) can communicate with nodes outside of its transmission range by employing intermediate nodes as relays. To find a path to a specific destination node, the source node broadcast route request packet that are forwarded to all other nodes. A simple flooding scheme is employed in AODV, where every node rebroadcasts these route request packets even if some of its neighbours have already broadcast the requests. So there is redundancy in broadcasting which could potentially leads to high channel contention and collision so the broadcast storm problem will occur in MANET. In order to avoid this broadcast problem different types of techniques was implemented such as simple flooding method, probability based method, area based method, neighbour knowledge based method, efficient and dynamic probabilistic broadcasting methods are used. Instead of power loss it cause link failure then the process of data transfer is terminate and it diminishes the overall the network performances and will cost a large amount of network resources. In this, paper it proposed a new way of broadcasting technique called "Efficient Power Aware broadcasts (EPAB)" to provide an optimal path with suitable bandwidth and battery capacity. EPAB will help in increasing the throughput by decreasing the packet loss due to non-availability of node having enough battery power to retransmit the data packet to next node.

Mobile Ad-hoc network is a collection of two or more node equipped with low power device for data transmission. Many Proactive based Power Aware Routing (PAR) protocol was implemented by many researchers. An optimized power reactive routing protocol describes the concepts of cognitive function and AODV protocol. It ensures that data packet is transferred in the shortest path and also in reliable mode. It will improve the data transmission with an energy efficient manner. A novel way of transmission was proposed using a technique called Optimized Power Reactive Routing (OPRR) for more splendid performances. This proposed protocol avoids new route discovery process in AODV with low power consumption and maintain stability of network. © 2011 IEEE.

Nowadays due to the increase in demand for various multimedia services requiring high capacity, shortage of wireless resources becomes a serious problem in cellular networks. It is difficult to suddenly increase the capacity of wireless communication networks because of high cost and complexity. In order to increase the capacity of wireless communication networks with minor changes and low cost, internetworking is needed. The main objective of SIP is to support the upper layer and mobility management protocols to optimize the handover process between heterogeneous networks such as Ethernet, Bluetooth, Wi-Fi, WiMAX, 802.11 and various other networks. The basic purpose of the SIP standard is to facilitate between heterogeneous networks to provide seamless mobility. This standard also supports handover for the both mobile as well as stationary users. For mobile users, handover can occur when wireless link condition changes due to Mobile Node (MN) movement. In this proposed work, Vertical handover is implemented between WLAN and WiMAX networks by using Session initiation protocol and the performance metrics such as Network delay, Neighbour advertisements, Handover delay and throughput were obtained. © 2014 IEEE.

Wireless sensor networks (WSN) are becoming an inevitable solution in industries for its automation and monitoring applications. Sensor nodes in WSN are deployed in fields with limited power. By nature these nodes are left unattended after deployment. This raises the importance of developing efficient algorithms which are capable of increasing the network lifetime by consuming less energy during the operations. This paper proposes a hybrid clustering energy aware routing protocol (H-CERP) for heterogeneous WSNs. H-CERP is designed to form efficient clusters with less cluster head count than the optimal estimation and uses multihop communication with gateway nodes to communicate with the base station. This novel approach makes our system more advantageous where the network lifetime and coverage of sensors are much vital at no additional cost. By deploying H-CERP in designed environment the results extracted shows promising results in terms of energy consumption, residual energy and lifetime of nodes when compared with generic methods like LEACH, PEGASIS and other recent techniques. © 2016 Springer Science+Business Media New York

Encryption is one of the fundamental technologies that is used in the security of multimedia data. Unlike ordinary computer applications, multimedia applications generate large amount of data that has to be processed in real time. This work investigates the problem of efficient multimedia data encryption. A scheme known as the Randomized Huffman Table scheme was recently proposed to achieve encryption along with compression. Though this scheme has several advantages it cannot overcome the chosen plaintext attack. An enhancement of this Huffman scheme is proposed in this work which essentially overcomes the attack and improves the security. The proposed encryption approach consists of two modules. The first module is the Randomized Huffman Table module, the output of which is fed to the second XOR module to enhance the performance. Security analysis shows that the proposed scheme can withstand the chosen plaintext attack. The efficiency and security of the proposed scheme makes it an ideal choice for real time secure multimedia applications. © 2011 Springer Science+Business Media, LLC.

Generally the low power consumption is achieved by unity power factor, so it has been considered as great concern in electrical systems. For the power factor improvement, different converters and control topologies are used. Power factor correction on interleaved bridgeless rectifier based on different current control technique is proposed in this paper. Major Strategies like a power factor improvement, harmonic reduction for interleaved type PFC converters are more suitable than conventional PFC converters. The proposed work is to investigate the efficient current controllers used to improve the input performance of UPS. © 2015 IEEE.
