Research ArticleOpen accessIn the keywordsRemote Personal Tracking System (RPTS)Abdfatah A. Yahya, Mahmoud Z. IskandaraniA novel system for remote tracking of personnel was proposed. The system was based on assuring that the moving tracked code belongs to the actual person assigned such a code by smelling and temperature measuring the person who holds such a device. The system would operate using a specific RF signal and allows for an accurate, economic and secure environment … …American Journal of Applied Sciences, Vol. 3, Issue 12 · 31 Dec 2006 · 7,691 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntrusion-Resistant Multi-Hop Communication Protocol for Secure Wireless Sensor NetworksRakesh Ranjan, Vaishali Singh, Hitendra SinghModern Internet of Things (IoT) systems are based on Wireless Sensor Networks (WSNs), which can be distributed to various environments to perform a range of sensing and data aggregation. Their intrinsic deficiencies in computation, energy, and bandwidth, however, make them very vulnerable to routing-layer attacks like black hole and selective forwarding as well as Sybil intrusion. The current studies on … …Journal of Computer Science, Vol. 22, Issue 6 · 1 Jul 2026 · 935 accessesView PDFCite
