Multi-hop cluster hierarchy has been presented as an organization for large wireless sensor networks (WSNs) that can provide scalable routing, data aggregation, and querying. In th...
Many applications in eLearning utilize wireless networks (WLAN) as a carrier for data and communication. These networks in their basic form are insecure, protecting the communicat...
Security in wireless sensor networks is currently provided exclusively through symmetric key cryptography. In this paper we show that special purpose ultra-low power hardware impl...
In a set of distributed wireless networks, such as globally distributed cellular systems, different networks could be administered by different operators. Mobile devices subscribe...
In distributed systems, transcoding techniques have been used to customize multimedia objects, utilizing trade-offs between the quality and sizes of these objects to provide diffe...
