More number of moving nodes makes them impenetrable genre which in turn makes the network intermittently connected. Detection of malicious node and routing is onerous due to its genre. In this paper, we put forward a secure routing that aids in detecting and preventing intrusion of malicious nodes. The routing process is made more adorable through Bee Colony Optimization (BCO). The amalgamation of BCO with authentication series leads a novel routing protocol named Privacy Preserving Bee Routing Protocol (PPBRP) which is highly secure. The degree of security is tested with malicious nodes in the network to prove that the proposed PPBRP ensures secure routing.展开更多

Routing allows us to implement many real world applications. Complete affinity in an infrequent network like ICMANET is highly impossible. Disconnected MANET is also known as ICMANET which is also a DTN (Delay Torrent Network) that supports for higher delays. It is laborious process to execute routing in a diffused network process to execute routing in a diffused network. To deliver the data packets towards the destined node to its best, a new strategy in routing called Ant routing protocol in concoction with storage strategy LoDis has been proposed. Despite of routing, security is still an unsolved problem. To evaluate this situation, this paper presents a methodology called agent technology which yields a secure routing. Hostile node in the network is spotted with the help of agent at each node. A cryptographic algorithm Advanced Encryption Standard (AES) is habituated to improve secure communication in wide range Mobility and total number of nodes in the network act as variables in examining the hostile nodes in the network to judge the standard of security. Improved performance along with the security is the point to be highlighted.展开更多

The performance of the proposed method deals with the emerging technique called as Motor Current Signature Analysis (MCSA) and the Zero-Sequence Voltage Component (ZSVC) to diagnose the stator faults of Induction Motors. The unalleviated study of the robustness of the industrial appliances is obligatory to verdict the fault of the machines at precipitate stages and thwart the machine from brutal damage. For all kinds of industry, a machine failure escorts to a diminution in production and cost increases. The Motor Current Signature Analysis (MCSA) is referred as the most predominant way to diagnose the faults of electrical machines. Since the detailed analysis of the current spectrum, the method will portray the typical fault state. This paper aims to present dissimilar stator faults which are classified under electrical faults using MCSA and the comparison of simulation and hardware results. The magnitude of these fault harmonics analyzes in detail by means of Finite-Element Method (FEM). The anticipated method can effectively perceive the trivial changes too during the operation of the motor and it shows in the results.展开更多

The compositions Ce0.85Gd0.15 - xCaxO2 - δ (x = 0.0 - 0.075) were prepared through sol-gel method. Their structure was studied by X-ray diffraction. Dense ceramic Ce0.85Gd0.15 - xCaxO2 - δ samples were prepared by sintering the pellets at 1300°C. The lattice parameter was calculated by Rietveld refinement of XRD patterns. Four probe A.C. impedance spectroscopy was used to study the total ionic conductivity of doped and co-doped ceria ceramics in the temperature range 200°C - 700°C. The Ce0.85Gd0.15 -xCaxO2 -δ composition showed maximum ionic conductivity with less activation energy.展开更多
