  1. Distributed Computation in MANets Robot swarm developed by James McLurkin @ Rice University

  2. The Setting • Wireless ad-hoc network • Small nodes with sensors, actuators • Chief concerns: • Energy efficiency! • Low computation power • Communication is expensive • Fault tolerance

  3. Example: Task Allocation • Each node “sees” some tasks it can do • Goal: partition tasks between nodes • Lower bound: #bits exchanged = • Even with only two robots, even with randomness • The upside: more robots = less individual load • With robots, tasks, “nice” input: bits per robot

  4. Main Challenges • Understand the interplay between • Computation power • Time required to finish • Communication cost • Tools: • Randomized algorithms • Optimization theory • Communication complexity
