A novel transmission power control protocol to extend the lifetime of sensor nodes and to increase the link reliability in wireless body area networks (WBANs) based on both short- and long-term link-state estimations is presented. Expand
RSSI/LQI-Based Transmission Power Control for Body Area Networks in Healthcare Environment
A novel transmission power control protocol for body area networks that controls the transmission power and avoids interference based on the link state using the RSSI and link quality indication. Expand
An intelligent agent-based routing structure for mobile sinks in WSNs
IAR, an Intelligent Agent-based Routing protocol that provides efficient data delivery to mobile sink is proposed and the proposed algorithm reduces signal overhead and improve degraded route called triangular routing problem. Expand
Multi-dimensional channel management scheme to avoid beacon collision in LR-WPAN
The simulation results demonstrate that the proposed scheme can minimize the possibility of beacon collisions by efficiently managing the multiple available channels in a hybrid manner combining proactive and reactive methods while the dissipated power consumption of PAN coordinator that uses MDS is more than that of PC that use IEEE 802.15.4.
