According to as urge in demand of wireless body area network (WBAN), there are many researches on WBAN based on standard IEEE 802.15.6. These researches focused on physical layer, media access control (MAC) layer and network layer based on IEEE 802.15.6. Since network topology in the standard is defined as one hop star plus one, the previous research focused on one hop star topology and a multiple hopstechnic wasn’t applied to WBAN. Based on network topology of WBAN, acluster-based meaning two hops technic is considered in this paper. Incluster-based WBAN, a cluster header (CH) forward the received data packet from a sensor to the coordinator, therefore, an over concentration that is a reason of deterioration of performance, can be avoided and then the performance of system is improved. However, the optimal access probability that can achieve the highest through put is changed depending on a number of clusters. The optimization method of access probability is proposed and the calculation result shows that the cluster-based topology system out performs one hop star topology.
