Outline • Introduction • Related Works • MRPC-MAC protocol • MRPC-Routing protocol • Simulation Results • Conclusions
Introduction • In wireless ad hoc networks • Power control • Save energy • Increase spatial reuse • Multi-Rate supported • Improve network throughput • What is right next hop relay?? • Routing protocol
Related Works • Power controlled MAC • Save the energy • Increase the throughput • Power controlled Routing • Find an end-to-end path with saving energy • Cross Layer Design • In this paper: MAC+ Routing protocol with power control for multi-rate ad hoc network
Assumption • STAs • Single radio • Single channel • Multi-Rate supported : ARF • MAC transmission failures or successes • Maintenance information of neighboring nodes m i j k
MRPC-MAC protocol m i j k
MRPC-MAC protocol • Overhearing RTS/CTS
Simulation Results • NS2.29
Conclusions • A new power controlled cross-layer • MRPC-MAC • MRPC-Routing • Improve the network throughput • Future work • Optimal the end-to-end path
