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

• STAs – Single radio– Single channel– Multi-Rate supported : ARF
• MAC transmission failures or successes– Maintenance information of neighboring nodes
