Performance evaluation of hybrid disaster recovery framework with D2D communications
Ever, Enver; Gemikonakli, Eser; Nguyen, Huan X.; Al-Turjman, Fadi; Yazıcı, Adnan (Elsevier BV, 2020-02-15)
Public Safety Networks (PSNs) provide assistance before- and post-disaster events. With the help of technological advances, PSNs are able to cope with both natural and man-made disasters, protecting people, environment and property. Effective communications, better situational awareness, lower response times and greater emergency efficiency are essential to an effective response to emergencies and disasters. Long Term Evolution (LTE) has been chosen to be the key technology for public safety networks. In th...
Optimized Unmanned Aerial Vehicles Deployment for Static and Mobile Targets' Monitoring
Al-Turjman, Fadi; Zahmatkesh, Hadi; Al-Oqily, Ibrhaim; Daboul, Reda (Elsevier BV, 2020-01-01)
In the recent decade, drones or Unmanned Aerial Vehicles (UAVs) are getting increasing attention by both industry and academia. Due to the support of advanced technologies, they might be soon an integral part of any smart-cities related project. In this paper, we propose a cost-effective framework related to the optimal placement of drones in order to monitor a set of static and/or dynamic targets in the IoT era. The main objective of this study is to minimize the total number of drones required to monitor ...
Second Chance: A Hybrid Approach for Dynamic Result Caching and Prefetching in Search Engines
Ozcan, Rifat; Altıngövde, İsmail Sengör; Barla Cambazoglu, B.; ULUSOY, ÖZGÜR (Association for Computing Machinery (ACM), 2013-12-01)
Web search engines are known to cache the results of previously issued queries. The stored results typically contain the document summaries and some data that is used to construct the final search result page returned to the user. An alternative strategy is to store in the cache only the result document IDs, which take much less space, allowing results of more queries to be cached. These two strategies lead to an interesting trade-off between the hit rate and the average query response latency. In this work...
Analyzing and Mining Comments and Comment Ratings on the Social Web
SİERSDORFER, Stefan; CHELARU, Sergiu; Pedro, Jose San; Altıngövde, İsmail Sengör; NEJDL, Wolfgang (Association for Computing Machinery (ACM), 2014-06-01)
An analysis of the social video sharing platform YouTube and the news aggregator Yahoo! News reveals the presence of vast amounts of community feedback through comments for published videos and news stories, as well as through metaratings for these comments. This article presents an in-depth study of commenting and comment rating behavior on a sample of more than 10 million user comments on YouTube and Yahoo! News. In this study, comment ratings are considered first-class citizens. Their dependencies with t...
How to construct optimal one-time signatures
Bicakci, K; Tsudik, G; Tung, B (Elsevier BV, 2003-10-22)
One-time signature (OTS) offer a viable alternative to public key-based digital signatures. OTS security is typically based only on the strength of the underlying one-way function and does not depend on the conjectured difficulty of some mathematical problem. Although many OTS methods have been proposed in the past, no solid foundation exists for judging their efficiency or optimality. This paper develops a methodology for evaluating OTS methods and presents optimal OTS techniques for a single OTS or a tree...
