    Background/Objectives: Due to direct implantation of sensor nodes on the body, temperature aware routing becomes critical and important technical issue to prevent damage of the tissue in wireless body area networks.

    Methods/Statistical analysis: To prevent temperature rise, most of existing routing protocols are likely to take approaches, either detouring the hot spot area or dropping packet to avoid the excessive high temperature. However, these operations may cause long delay and low packet delivery ratio, accordingly. Thus, a new approach to adjust temperature of sensor node is demanded.

    Findings: Unlike the existing protocols, we make use of mobile node to carry packet to the sink whenever any hot spot is found along the forwarding path. Thus, alternative path around hot spot becomes one of two, that is, detour and mobile path, according to expected delay to the sink. As compared to existing schemes, the proposed scheme does not cause overhead by making use of mobile node which is already implemented but not take any specific task for temperature control. Simulation results demonstrate that the proposed scheme can improve packet delivery ratio as well as reduce end-to-end delay rather than existing protocol.

    Improvements/Applications: Improved routing algorithm was proposed to make use of mobile nodes and thereby to prove the applicability of the proposed scheme in wireless body networks.
