A hierarchical polling-based access scheme for Wireless Body Sensor Network (WBSN) is proposed in this paper. The proposed access scheme is structured in hierarchy to collect data from sensor nodes inserted in human body. In first level of hierarchy the sensor nodes are divided into groups and sensor nodes of each group communicate with a sink node which collects data by using polling technique. In second level, the sink nodes communicate with a master node which collects data by also using polling technique. To study the performance of proposed scheme, two cases are considered.
