  1. Design and Analysis of On-Demand Loop-Free Hybrid Multipath Routing for Mobile Ad Hoc Networks

  2. Difference between OLFHMR and OHMR • OLFHMR modifies OHMR by piggybacking a “alt_num” field to the RREP packets. • The “alt_num” field represent i-th node on the primary path

  3. RREQ D S

  5. Field value When the field “alt_num” is one byte • “alt_num=0” represent the primary path • “alt_num=255” represent • “alt_num=1~254” represent the alternate path
