In this paper we propose an algorithm for exhaustive search of GIS Mobile query (pointin-area function). This algorithm search the status of a given co-ordinate point with respect to an area (described as a set of co-ordinates without any geometric relationship). In the exhaustive search algorithm proposed previously, there were a number of undetermined points (which does not support the range of scale), which are close to boundary co-ordinates. In this paper a new approach is introduced by which much accurate result can be obtained.

Many hierarchical reliable multicast (HRM) protocols deploy repair proxies that perform local recovery and feedback consolidation. Placement of proxies is a key design issue in HRM network. The objective of Greedy-MRS algorithm is to place the HRM proxy in a single iteration, but it requires communication with routers frequently to find the efficient proxy. The objective of preprocessing step is to communicate with routers to implement Greedy–MRS algorithm with minimum number of communications between routers. Space needed in the router to store data to find efficient placement of proxies for HRM network is constant and it is independent of number of children. Simulation results indicate that this preprocessing step providing good levels of space and communication complexity and scalability of this algorithm depends on height of subtree.

A damage or breakage of Critical Infrastructure or CI will have a huge effect on humanity and economy. Supervisory Control and Data Acquisition Systems (SCADA) play a big role on Critical Infrastructure since most of these infrastructures are controlled by control systems like SCADA. In this paper, we assess vulnerabilities of a SCADA system, its effect to the society and the ways to prevent such vulnerabilities. We also researched on the background of the SCADA system and its comparability to the common computer system is discussed.

A lot of time and for many reasons, vaccination schedule of children isn’ t maintained adequately and vaccines get missed or delayed. Until now, a very complicated set of calculations needed to be made before administering any missed or late vaccination dose. The positive impact and importance of vaccination in early childhood stage of a person is undeniably true. Diseases can be prevented by proper immunization procedures, however, with most parents working in this generation and not most clinics pay much attention on the individual planning and notifications of their patients, this research will show a solution to such crucial issue. The research depicts an architectural structure using mobile computing which will plot a chart of vaccination planner synchronous with the parent’ s personal planner so as to set a schedule amenable to both the parties and a notification through will be generated. This will be a tool for parents and assistance to clinics and hospitals catering vaccinations shots for children.

Penetration testing is one of the oldest methods for assessing the security of a computer system. The idea behind penetration testing methodologies is that the penetration tester should follow a pre-scripted format during test as dictated by the methodology. A penetration testing methodology was proposed in this research. It is also important to consider a policy that should be followed by both the tester and the client to reduce financial and confidential disparities, and to bring conformity to the operations between the both parties, so this research suggests a policy that should be followed by penetration testers and clients of the penetration tests.
