Security schemes of pairwise key establishment, which enable sensors to communicate with each other se-curely, play a fundamental role in research on security i
Wireless sensor networks (WSNs) are mostly deployed in a remote working environment, since sensor nodes are small in size, cost-efficient, low-power devices, an
This paper presents a frequency synthesizer architecture based on the time delay digital tanlock loop (TDTL). The loop is of the first order type. The synthesiz
