MAC-Network Cross-Layer Energy Optimization model for Wireless Body Area Networks

Résumé

—In recent years, Wireless Body Area Networks (WBANs) have gained increasing interest in the research community and become an emerging technology, especially in healthcare services. This position paper focuses on the energy optimization issue and the joint routing and MAC protocols in WBANs. We extend upon our previous model on the Energy-Aware Topology Design for WBANs (EAWD), so as to include PHY and MAC-layer WBAN specifications. Indeed, EAWD model considered the topology constraints by minimizing the number of relay nodes, in order to reduce the total energy consumption, as well as the total network installation cost. Yet, EAWD involved quite rough assumptions, omitting overhead considerations, due to MAC routing and physical clear channel assessment problems. Therefore, we first introduce the EAWD model and discuss its limitations. Then, we present our proposal, the Enhanced EAWD (EEAWD), and assess its performance through a synthesis comparison with EAWD and related proposals in the literature.
