In this paper, a wireless body area network comprised of heterogeneous sensors is developed for wearable health monitoring applications. The ultimate application space is in the context of pediatric obesity. The specific task examined herein is activity detection based on heart rate monitor and accelerometer data. Based on statistical analysis of(More)
— A new technique titled " Particle Refresh " and a hybridization with conjugate gradient method are introduced to particle swarm optimization (PSO). The former charges power to inactive particle to improve the recovery ability of PSO after trapping on a local solution, and as a result, it becomes easy to choose suitable values for control-parameters to(More)
