Special Interest Group E - Body Communications

Co-Chairmen: Prof. Jun-ichi Takada, Tokyo Institute of Technology-NICT, Japan, and Dr. Arie Reichman, Ruppin Academic Center-Tel Aviv University, Israel

Recent advances in wireless technology have led to the development of Wireless Body Area Networks (WBAN), where a set of communicating devices are located around the human body. In the case of medical applications, these devices are connected to sensors that monitor vital body parameters and movements. The WBAN have been considered not only for the medical and healthcare applications but as well as for sports and entertainment.

The body area channel is very different from other wireless channels in the sense that the antenna - human body interaction is an integral part of the channel. Propagation in WBAN is indeed confined within a limited range around human body where transmitter and receiver are almost co-located to each other.

This network comprises a series of miniature sensor/actuator nodes each of which has its own energy supply for autonomous operation. The nodes will have enough intelligence to carry out their task and will be able to communicate with other sensor nodes or with a central node worn on the body.

Body area networks address a technology segment not currently covered by existing connectivity standards. The aim is to provide a broad range of data rates at much lower power consumption than current standards with the explicit assumption that the range to be covered be limited to the immediate environment around and within a person's body.

This Special Interest Group mainly focuses on the following topics related to body communications:

  • Requirements for body communications
  • Scenarios of operations
  • Wearable antennas
  • Propagation models
  • System and network architectures
  • Air interfaces
  • Relation to PAN, LAN, WAN
