In Wireless Body Area Network (WBAN), detection of fault node improves reliability and security for long range transmission. In this paper, the authors propose a combined approach for reliable and secured data transmission in WBAN. The proposed architecture consists of sensor nodes, relay nodes, the intermediate processing nodes and Body Area Network (BAN) coordinator where the nodes are modeled to have direct and relay mode. The secured communication is ensured among the node and BAN coordinator by following simple protocol. The secure data transmission is proposed through authentication check, duplication check and faulty node detection. The proposed method is applicable to long ranges of transmission. It is also supporting a retransmission concept.
