CLUSTER COOPERATION IN WIRELESS-POWERED SENSOR NETWORKS: MODELING AND PERFORMANCE ANALYSIS

A wireless-powered sensor network (WPSN) consisting of one hybrid access point (HAP), a near cluster and the corresponding far cluster is investigated in this paper.These sensors are wireless-powered and they transmit information by consuming the harvested energy from signal ejected by the HAP.Sensors are able to harvest energy as well as store the
