A new backoff scheme named Unique Backoff Algorithm (UBA) has been introduced in this paper for IEEE 802.15.6 Wireless Body Area Networks (WBANs). This scheme tries to eliminate the collision among nodes by assigning unique backoff values. UBA removes the large delays during transmissions between different nodes and hence increases overall system performance. Furthermore, the concept of Backup Slot ($BS$) has also been introduced in the superframe to accommodate one failure of highest priority in the current superframe. For evaluation, proposed scheme has been simulated in comparison with the Binary Exponential Backoff (BEB) using different priorities. Results show that our scheme outperforms BEB in terms of throughput and superframe efficiency.
