This is not only because some service requests a high quality and real time transportation, but also because other services such as the capacity greedy applications request a higher bandwidth. In the meantime, has been the hybrid architecture consists of IP/MPLS domain and ASON/GMPLS optical domain projected as the infrastructure of the future internet. This architecture supports the transportation of the in near future expected data traffic on the ASON/GMPLS over DWDM optical domain, whereas it supports all the IP based service applications using the IP/MPLS domain. However, supporting service differentiation in multi-domain multilayer optical networks require the invention on routing scheme that supports both routing policies, the Physical Topology First (PTF) and Virtual Topology First (VTP), which are used to accommodate traffic in multilayer networks. In this work we use a hierarchical routing algorithm to evaluate the service differentiation schemes that are known in the literature in an IP/MPLS over ASON/GMPLS multi-domain network scenario, these service differentiation schemes are the Routing Policy Differentiation (RPD), Virtual Topology Differentiation (VTD) and Virtual Topology Sharing (VTS).&nbsp;</p> Wajdi Halabi Copyright (c) 2020 International Journal of Computer (IJC) https://creativecommons.org/licenses/by-nc-nd/4.0 2020-01-29 2020-01-29 36 1 1 17 Exploring Impacts of Random Proactive Jamming Attack in Wireless Sensor Network https://ijcjournal.org/index.php/InternationalJournalOfComputer/article/view/1500 <p>Wireless Sensor networks are one of the most extensively used technologies in our day to day lives; they can provide communication without needing a fixed infrastructure, which makes them suitable for communication in disaster areas or when quick deployment is needed. However, this kinds of network technology uses the wireless medium for communication. It is vulnerable to malicious attacks. One of the most frequently used attacks is a random jamming attacks which is Denial of Service attack. Random Jamming attacks disturb the communication between Sink and legitimate nodes. In rough environments where there is constant traffic, Random jamming attack can cause serious problems. Because of this, a study of random jamming attacks and how to prevent them is necessary. In this research the random jamming attacks were simulated using Riverbed Modeler software, in order to provide a better understanding of effects of random jamming attacks. This study will be helpful for future research and development of a practical, effective way to avoid random jamming attacks. The objectives of this thesis were to simulate and analysis wireless sensor network (ZigBee) under random jamming attacks; launch different kinds of (fixed, mobile) random jamming attacks in order to test how much influence on performance of wireless sensor network. Riverbed Modeler Based simulation which have five scenarios were created and the simulation was run and the results were collected, which shows that the throughput of the wireless sensor network decrease and increase the delay ,data drop when the network is affected by the random Jammers. Finally, thesis describe the open issues in this field, such as adding more than one random jammer and sink in wireless sensor network.</p> Ali Mohammed Hussen Copyright (c) 2020 International Journal of Computer (IJC) https://creativecommons.org/licenses/by-nc-nd/4.0 2020-02-11 2020-02-11 36 1 18 33 Crowdsourced Machine Learning Based Recommender for Software Design Patterns https://ijcjournal.org/index.php/InternationalJournalOfComputer/article/view/1541 <p>Software technology has become an essential part of human lives today. The role of software Engineers in making this technology as success is very fundamental. In software Engineering, the toughest stage is to design software as there is no particular rule or formula to covert requirements into design representation. A designer designs software using skills, critical thinking ability and previous experience only. To make this process easy, the design patterns came into existence which are the solutions that can be used repetitively to solve design problems. There have been several pieces of research presented regarding design Patterns but it is hard to find research regarding how the patterns are perceived and used in industries today and what nature of application uses which specific patterns. This paper uses a crowdsourced approach to acquire the finest practices that are being used in industries today including which quality attributes are affected most by the implementation of these patterns and which patterns are suitable for what type of applications. It also uses a machine learning supervised algorithm (Matchbox Recommender) to predict suitable design pattern for different nature of applications.</p> Sunbul Sajid Khowaja Dr Qasim Ali Erum Hamid Rajesh Kumar Gul Bano Jatendar Dharani Isma Farah Zainab Umair Copyright (c) 2020 International Journal of Computer (IJC) https://creativecommons.org/licenses/by-nc-nd/4.0 2020-02-20 2020-02-20 36 1 34 52
