Mini Overview of Key Issues in Routing for OSPF MANETs(CTCSA)-Lupine Publishers

Mini Overview of Key Issues in Routing for OSPF MANETs(CTCSA)-Lupine Publishers
Open Shortest Path First (OSPF) is a well known and prominent Internet Protocol (IP) for network routing. By deploying a link state routing (LSR) algorithm OSPF comes under the category of interior gateway routing protocols. In today’s wireless ad hoc Internet, the current routing domain needs to maintain a peak level of service accessibility and availability, thus OSPF must be extended to the wireless ad hoc network for maximizing routing performance in the network by taking into account key routing issues, i.e., optimal Hello Interval, efficient flooding schemes, optimizing the traffic engineering related issues, optimum adjacency creations, connectivity factors, reducing control overhead, and QoS and security challenges.

Numerical Solution of Boundary Layer Flow of Viscous Fluid Via Successive Linearization Method(CTCSA)- Lupine Publishers

Numerical Solution of Boundary Layer Flow of Viscous Fluid Via Successive Linearization Method(CTCSA)-Lupine Publishers


The aim of this work is to obtain the numerical solutions for the boundary layer flow of heat transfer of incompressible viscous fluid. The governing partial differential equations are converted into ordinary differential equation by using a similarity transformation. The nonlinear equation governing the flow problem is modeled and then solved numerically by means of a successive linearization method (SLM). The numerical results are derived in tables for comparisons. The important result of this comparison is to show the high precision of the SLM in solving system of nonlinear differential equations. Graphical outcomes of various parameters such as Prandtl number (Pr) and Eckert number (Ec) on the flow, field are discussed and analyzed.

Mitigating Disaster using Secure Threshold-Cloud Architecture(CTCSA)- Lupine Publishers

Mitigating Disaster using Secure Threshold-Cloud Architecture(CTCSA)-Lupinepublishers
There are many risks in moving data into public cloud environments, along with an increasing threat around large-scale data leakage during cloud outages. This work aims to apply secret sharing methods as used in cryptography to create shares of cryptographic key, disperse and recover the key when needed in a multi-cloud environment. It also aims to prove that the combination of secret sharing scheme and multi-clouds can be used to provide a new direction in disaster management by using it to mitigate cloud outages rather than current designs of recovery after the outages. Experiments were performed using ten different cloud services providers at share policies of 2 from 5, 3 from 5, 4 from 5, 4 from 10, 6 from 10 and 8 from 10 for which at different times of cloud outages key recovery were still possible and even faster compared to normal situations.
