  Software connectors play an important role in distributed system. In recent years, software developers have been facing more challenges of connectors which are used to connect distributed components. Design of connectors ...
• Trust-aware monitoring scheme for WiMAX networks 

  Safa H.; Shahla F.A. (, 2010)

  The IEEE 802.16 standard, the service data units deemed to exceed the granted bandwidth may be delayed or dropped. In addition, nodes would behave maliciously by requesting more resources than their requirements just to ...
• A transport layer interoperability model for mobile ad-hoc environment 

  Safa H.; Karam M.; Assi R.A.; Mcheick H. (, 2011)

  Mobile ad-hoc networks (MANETs) are dynamic in nature. Links between nodes may constantly change due to mobility. The performance of the transmission control protocol (TCP) degrades in such an environment mainly due to its ...
• Early adaptation aspects extraction in web development 

  Dargham J.; Aoude L.; Karam M. (, 2011)

  One important issue that pleases the web applications' users and draws their attention is the adaptability of the application manipulated, where web pages can change content upon user's needs and characteristics. Some ...
• On the refinement of liveness properties of distributed systems 

  Attie P.C. (DORDRECHTVAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS, 2011)

  We present a new approach, based on simulation relations, for reasoning about liveness properties of distributed systems. Our contribution consists of (1) a formalism for defining liveness properties, (2) a proof method ...
• Mesh cutting during real-time physical simulation 

  Turkiyyah G.M.; Karam W.B.; Ajami Z.; Nasri A. (OXFORDTHE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLAND, 2011)

  The ability to cut through meshes in real-time is an essential ingredient in a number of practical interactive simulations. Surgical simulation, cloth design, clay sculpting and many other related VR applications require ...
• Dominating set-based location management architecture for mobile IP networks 

  Safa H.; Kassab W. (, 2009)

  Mobile IPv4 and Mobile IPv6 were proposed to extend the IP protocol to support mobility. They use two IP addresses: a home network address that is used as a permanent identification address, and a care-of-address acquired ...
• Assisting students with typical programming errors during a coding session 

  Karam M.; Awa M.; Carbone A.; Dargham J. (, 2010)

  Typical programming errors that introductory students make are known to stall and frustrate them during their first few lab coding sessions. Traditionally, lab instructors help with the process of correcting these errors; ...
• Reactive localization in underwater wireless sensor networks 

  Watfa M.K.; Nsouli T.; Al-Ayache M.; Ayyash O. (, 2010)

  In this paper, we present a novel technique for localizing an event of interest in an underwater environment. The network consists of randomly deployed identical sensor nodes. Instead of proactively localizing every single ...
• Relaxing result accuracy for performance in publish-subscribe systems 

  Bashir E.; Boulos J. (, 2005)

  Since the evaluation of XPath expressions is highly dependent upon their size and navigational structures that include ancestor-descendant relationships (--) and wildcard steps (-*), we introduce a novel and complementary ...
• An empirical evaluation of test case filtering techniques based on exercising complex information flows 

  Leon D.; Masri W.; Podgurski A. (, 2005)

  Some software defects trigger failures only when certain complex information flows occur within the software. Profiling and analyzing such flows therefore provides a potentially important basis for filtering test cases. ...
• An inductive logic programming approach to validate hexose binding biochemical knowledge 

  Nassif H.; Al-Ali H.; Khuri S.; Keirouz W.; Page D. (, 2010)

  Hexoses are simple sugars that play a key role in many cellular pathways, and in the regulation of development and disease mechanisms. Current protein-sugar computational models are based, at least partially, on prior ...
• Service discovery in mobile ad-hoc networks 

  Safa H.; Koteiche Z. (IGI Global;, 2010)

  Service discovery plays a relevant role in mobile ad hoc environments. Indeed, upon joining a self-organizing network, mobile nodes should be able to explore the environment to learn about, locate, and share the available ...
• A hybrid DV-Hop for localization in large scale Wireless Sensor Networks 

  Yassine F.; Safa H. (, 2009)

  Localization has been a major challenge in Wireless Sensor Networks (WSN) because without finding the position of the sensor that is reporting sensed data, the data reported will not be useful. However, most of the previous ...
• Cache-oblivious polygon indecomposability testing 

  Salem F.K.A. (, 2010)

  We examine a cache-oblivious reformulation of the (iterative) polygon indecomposability test of [19]. We analyse the cache complexity of the iterative version of this test within the ideal-cache model and identify the ...
