Wireless Body Area Networks (WBANs) are particular field of Wireless Sensor Networks (WSNs). It is the important building segments of forthcoming networks. Contemporary health care structure is one of the furthermost standard WBAN applications. In recent decades, study has focused on channel modeling, energy consumption strategy of well-organized medium access control (MAC) protocols. In this form of network, the number of sensors which are used in the network topology has been significantly reduced than existing WBAN. In this paper, we have evaluated TDMA based MAC protocol performance through several metrics. In this paper TDMA approach is used to avoid packet collision which leads to higher packet loss rate. Clock synchronization is the solution of problem like packet collision. After clocks of WBAN sensor nodes are synchronized, data can be transferred between sensor nodes and sink efficiently and rapidly.
