  7. Abstract:
  8. This research presents an efficient thermal-aware routing protocol based on Shortest Hop Routing algorithms for implanted bi medical sensor network. Implanted biomedical sensor networks provide a major application of sensor networks in the near future. These in-vivo sensor nodes collect desired biometric data and communicate the data wirelessly to a base-station through a multi-hop network. They generate the heat due to wireless communication and circuitry power consumption. A high temperature of the in-vivo nodes for a prolonged period might damage the surrounding tissues. Most of the protocols for sensor networks don’t take the thermal issue as a factor in the routing of packets. In its simplest form, our proposed protocol state that when some nodes in the shortest path have a high temperature, the protocol ignores this path and routes packets through other paths whose nodes have lower temperatures. The simulation results indicate the superiority of the proposed method compared to Thermal Aware Routing Algorithm (TARA) and Hotspot Preventing Routing (HPR) in terms of reducing temperature without a significant increase in packet delivery delay and power consumption of nodes. It is highly scalable, increases the operational life of network and helps reduce the number of packets dropped
