Wireless Multimedia Sensor Networks (WMSNs) are wireless connected sensor’s with audio and video capabilities in addition to scalar sensing. Limited availability of bandwidth is a major constraint for multimedia data in WMSNs. The requirement of real time streaming poses another challenge in the network. Medium access control (MAC) protocols designed for traditional wireless sensor networks can...

Originator Control is an access control policy that requires recipients to gain originator’s approval for redissemination of disseminated digital object. Originator control policies are one of the generic and key concerns of usage control. Usage control is an emerging concept which encompasses traditional access control and digital rights management solutions. However, current commercial Digita...

The development of complex access control architectures raises the problem of their management. In this article, we describe an architecture providing packet filters configuration in Internet based networks. The performance of the access control process heavily depends on the number of rules used to define the access control service. Therefore an efficient access control architecture relies on ...

the aim of the present study was to explore the relationship between media literacy and social skills among citizens in isfahan. to this end, a descriptive-correlation methodology was employed. the population under study consisted of all citizens living in isfahan who were reported to be 1796967 persons in 2013. using cochran formula, 384 persons were selected by stratified sampling and were in...

In this paper we present an analysis of a MAC (Medium Access Control) protocol for wireless sensor networks. The purpose of this protocol is to manage wireless media access by constructing a Time Division Media Access (TDMA) schedule. APMC (Approximate Probabilistic Model Checker) is a tool that uses approximation-based verification techniques in order to analyse the behavior of complex probabi...

Son zamanlarda doğrusal topolojiye sahip Kablosuz Algılayıcı Ağ (KAA) uygulamalarının kullanımı gerçek dünyada oldukça popüler olmaya başlamıştır. Bu sebeple, bu alanda yapılan akademik çalışmaların sayısı gün geçtikçe artmaktadır. Otoyollar, köprüler, boru hatları ve sınır boylarının izlenmesi gibi uygulama alanına özel geliştirilen Doğrusal (DKAA) uygulamalarına da sıkça rastlanmaktadır. KAA’...
