Many large-scaled servers are implemented as a peer-to-peer (P2P) distributed system to avoid centralized management and increase scalability. Traditional P2P lookup protocols often utilize binomial lookup trees to shorten lookup paths. Such a lookup protocol introduces routing bottlenecks when certain nodes become hot spots. In this paper, we present a(More)
This paper presents a wireless biosignal acquisition system-on-a-chip (WBSA-SoC) specialized for electrocardiogram (ECG) monitoring. The proposed system consists of three subsystems, namely, 1) the ECG acquisition node, 2) the protocol for standard IEEE 802.15.4 ZigBee system, and 3) the RF transmitter circuits. The ZigBee protocol is adopted for wireless(More)
