#### Taxonomy of Routing Protocols in WBAN
The routing protocols based on cross-layered routing protocols are Wireless Autonomous Spanning Tree Protocol (WASP) [67], Cascading Information Retrieval by Controlling Access with Dynamic Slot Assignment (CICADA) [68], Timezone Coordinated Sleeping Scheduling (TICOSS) [69], Biocomm [70] and Biocomm-D [70]. Based on the comprehensive analysis of state-of-the-art approaches in the field, limitations of available thermal-aware techniques are described in Table 1. \begin{table}
