  1. Useful theory? Koen Langendoen Theory & Practice in Wireless Networks Los Angeles, May 20 – 21, 2008

  2. Background WSN research • MAC protocols • localization • deployments precision agriculture

  3. Software crisis • state-space explosion • design & test  Theory is needed Experiences Murphy loves potatoes • 2% data yield • 98% bug yield "In theory, there is no difference between theory and practice. But, in practice, there is.” Jan L. A. van de Snepscheut

  4. theory practice

  5. Customer of theory • correctness proofs • bounds • algorithms

  6. WSN detailsthat matter • Cost • energy (#msgs) • memory footprint • Communication • unicast != broadcast • (un)reliable • Synchronization (no)

  7. Common practice IPSN 2005–2007 and DCOSS 2005–2006 (theory), SenSys 2005–2006 and EWSN 2006–2007 conferences (systems)

  8. Advice • account for unreliable communication • correctness / stability • performance • quantify communication cost • differentiate ucast/bcast • use reactive protocols (vs. synchronized rounds)
