World of Computer Science and Information Technology Journal Finding Shortest Path for Developed Cognitive Map Using Medial Axis Abstract: this paper presents an enhancement of the medial axis algorithm  to be used for finding the optimal shortest path for developed cognitive  map. The cognitive map has been developed, based on the architectural  blueprint maps. The idea for using the medial-axis is to find main path  central pixels; each center pixel represents the center distance between  two side boarder pixels. The need for these pixels in the algorithm comes  from the need of building a network of nodes for the path, where each  node represents a turning in the real world (left, right, critical left, critical  right…). The algorithm also ignores from finding the center pixels paths  that are too small for intelligent robot navigation. The Idea of this  algorithm is to find the possible shortest path between start and end  points. The goal of this research is to extract a simple, robust  representation of the shape of the cognitive map together with the optimal  shortest path between start and end points. The intelligent robot will use  this algorithm in order to decrease the time that is needed for sweeping  the targeted building..  Keywords : Artificial Intelligence; Cognitive Map; Image Processing; Robot, Medial Axis; Shortest Path. Validation Measures in CMMI Abstract: Validation is one of the software engineering disciplines that help  build quality into software. The major objective of software validation  process is to determine that the software performs its intended functions  correctly and provide information about its quality and reliability.  This paper identifies general measures for the specific goals and its  specific practices of Validation Process Area (PA) in Capability Maturity  Model Integration (CMMI). CMMI is developed by Software Engineering  Institute (SEI). CMMI is a framework for improvement and assessment of a  software development process. CMMI needs a measurement program that is practical. The method we used to define the measures is to apply the Goal  Question Metrics (GQM) paradigm to the specific goals and its   specific  practices of Validation Process Area in CMMI. Keywords : Validation; Measures; CMMI; GQM. Authors Hazim A. Farhan Hussein H. Owaied Suhaib I. Al-Ghazi Using Short Message Service (SMS) to Support Business Continuity  Abstract: Now a day's many organizations are required to communicate  online on a daily basis, 24-hour, seven-days-a-week, to gain the desired  competitive advantages and profits; although there are a variety of  disruptions that may occur within business application such as broken (off-  line) database-links and unhanded database exceptions. Such cases will  end the automated business work, and force business users to continue  business procedures and functionalities via paper work, which causes  additional resources with less business competitive advantages. In this  paper, we will propose a new model in which we embed short message  services (SMS) within business applications using the SMS Gateway such as  "Ozeki Message Server", and programmed application packages. By using  our proposed model, we can maintain business continuity when a partial  disruption occurs and then switch to our application model. As a result to  the experimental work, we conclude that our model supports business  continuity since it supports the account balance modification while the  database link is disrupted. In addition, we carried out each step twice and  the scenario was reliable since all of its steps were reliable.  Keywords : Business Continuity; Short Message Service; Ozeki Message Server; Tasks Automation; SMS Technology. SLDs for Visualizing Multicolor Elevation Contour Lines in Geo-Spatial Web Applications Abstract: This paper addresses the need for geospatial consumers (either  humans or machines) to visualize multicolored elevation contour poly lines  with respect their different contour intervals and control the visual  portrayal of the data with which they work. The current OpenGIS Web Map  Service (WMS) specification supports the ability for an information provider to specify very basic styling options by advertising a preset collection of  visual portrayals for each available data set. However, while a WMS  currently can provide the user with a choice of style options, the WMS can  only tell the user the name of each style. It cannot tell the user what  portrayal will look like on the map. More importantly, the user has no way  of defining their own styling rules. The ability for a human or machine  client to define these rules requires a styling language that the client and  server can both understand. Defining this language, called the  StyledLayerDescriptor (SLD), is the main focus of this paper, and it can be  used to portray the output of Web Map Servers, Web Feature Servers and  Web Coverage Servers. Keywords : Styled Layer Descriptors; GIS; Contour Lines; Web Map Services; XML. Optimal Cell Towers Distribution by using Spatial Mining and Geographic Information SystemSystem Abstract: The appearance of wireless communication is dramatically  changing our life. Mobile telecommunications emerged as a technological  marvel allowing for access to personal and other services, devices,  computation and communication, in any place and at any time through  effortless plug and play. Setting up wireless mobile networks often  requires: Frequency Assignment, Communication Protocol selection,  Routing schemes selection, and cells towers distributions. This research  aims to optimize the cells towers distribution using spatial mining with  Geographic Information System (GIS) as a tool. The proposed optimized  towers distribution done by applying the Digital Elevation Model (DEM) on  the image of the targeted area should be covered. DEM applied with two  levels of hierarchy, first level for getting the cells and second for getting  best location in each cell. The research will apply the spatial association  rules technique on the second level to select the best square in the cell for  placing the antenna. From that the proposal will try to minimize the  number of installed towers, makes tower's location feasible, and provides  full area coverage.   Keywords : Tower; Tower locations; Spatial mining; Digital Elevation Model; Database; and spatial association Rules. Performance Analysis of AODV under Black Hole Attack through Use of OPNET Simulator Abstract: Mobile ad hoc networks (MANETs) are dynamic wireless networks  without any infrastructure. These networks are weak against many types of  attacks. One of these attacks is the black hole. In this attack, a malicious  node advertises itself as having freshest or shortest path to specific node  to absorb packets to itself. The effect of black hole attack on ad hoc  network using AODV as a routing protocol will be examined in this  research. Furthermore, we investigate solution for increasing security in  these networks. Simulation results using OPNET simulator depict that  packet delivery ratio in the presence of malicious nodes, reduces notably.   Keywords : AODV; black hole attack; packet delivery ratio; OPNET.
