Data aggregation processes aim to reduce the amount of exchanged data in wireless sensor networks and consequently minimize the packet overhead and optimize energy efficiency. Securing the data aggregation process is a real challenge since the aggregation nodes must access the relayed data to apply the aggregation functions. The data aggregation security problem has been widely addressed in cla...

The wireless communication with delivering variety of services to users is growing rapidly in recent years. The third generation of cellular networks (3G), and local wireless networks (WLAN) are the two widely used technologies in wireless networks. 3G networks have the capability of covering a vast area; while, WLAN networks provide higher transmission rates with less coverage. Since the two n...

Over the last years, computer networks have evolved into highly dynamic and interconnected environments, involving multiple heterogeneous devices and providing a myriad of services on top of them. This complex landscape has made it extremely difficult for security administrators to keep accurate and be effective in protecting their systems against cyber threats. In this paper, we describe our v...

مدیریت سازه­های ناهمگن قومی امری به مراتب مشکل­تر از اداره واحدهای سیاسی همگن قومی، زبانی و مذهبی است. از این رو سازماندهی سیاسی فضا و آمایش سرزمین، ماهیت قوانین از جنبه تئوریک و عملی، سیاست­های اقتصادی، فرهنگی، اجتماعی، سیاسی و... مستلزم تعریفی است که همگرایی معنوی برونداد نهایی آن باشد. چنین وضعیتی بدون رعایت عدالت جغرافیایی در صور گوناگون از پایداری لازم به دور خواهد بود. اهمیت شرایط فوق با ...
