Radio frequency identification (RFID) is lagging behind because of vendor specific solutions and expensive implementation cost. In particular, the reader is the most expensive part. A WiFi compatible tag was proposed to use the WNIC as an RFID reader. However, no specific modulator or demodulator was suggested. This paper analyzes the various IEEE 802.11(More)
Designing a compact, power efficient voltage controlled oscillator (VCO) for high frequency phase lock loop (PLL) in modern wireless communication system is decisively a challenging task. Inappropriately designed VCOs for battery-powered radio frequency identification (RFID) transponder cause huge degradation of overall system. The proposed work presents a(More)
Probabilistic routing in wireless sensor network (WSNs) use the mobility history when making a forwarding decision. This type of routing provides a very rapid development and new perspectives in WSNs. However, there are several constraints and challenges to overcome the security problems. In this paper, we propose a security solution based on the RAID5(More)
