  1. Loop-Based Source Routing Protocol for Mobile Ad-hoc Networks Yosuke Sagawa, Tomonori Asano and Hiroaki Higaki Advanced Information Networking and Applications (AINA’03) shinzi

  2. Outline • Introduction • Related work • LBSR Protocol • Conclusions shinzi

  3. Introduction • A routing protocol which detects a transmission route from a source host to destination host is critical • Mobility • Limited battery capacity • A communication link between two mobile computers is not always bi-directional • This paper proposes • LBSR (Loop-Based Source Routing) Protocol • Supporting uni-directional links shinzi

  4. Introduction (cont.) shinzi

  5. Related work • Flooding of Rreq in DSR shinzi

  6. Related work (cont.) • Flooding of Rrep in DSR shinzi

  7. LBSR Protocol • In DSR protocol • RS->D and RD->S are detected independently • In LBSR protocol • S detects a looped route RS->D + RD->S containing both S and D shinzi

  8. LBSR Protocol (cont.) Lreq packet shinzi
