Energy-efficient communication protocol is a pri- mary design goal for Wireless Sensor Networks (WSNs). Many efforts have been done to save energy: MAC with duty cycle, energy-aware routing protocols, data aggregation schemes, etc. Recently, beacon-less strategies have emerged as new direction to improve considerably the WSN lifetime. However, the main contributions are not suitable to real radio environments be- cause of hole avoiding strategies based on either planarization or explicit neighbor solicitations. We propose PFMAC (Pizza- Forwarding Medium Access Control), which combines beacon- less geo-routing and energy efficient MAC protocol via a cross- layer design to save more energy with higher reliability. PFMAC supports radio interferences, asymmetric radio links, etc. PFMAC supports a greedy forwarding strategy and, a reactive and optimized neighborhood discovery at 2-hop to deal with holes. Intensive simulations are proposed to highlight the behavior and the performance of PFMAC compared to BOSS over BMAC.
