Bog'liq taqsimlangan O‘zbekiston respublikasi oliy va o‘rta maxsus ta’lim vazirligi u, 1111Sensor Network Mobile robots - I-Swarm Robot
- (See a video of the I-Swarm
- Robots on YouTube)
- The I-Swarm project, consisting of 10 research institutes,
- is coordinated by Professor Heinz Wörn and Jörg Seyfried
- of the University of Karsruhe in Germany.
- The computers coordinate their activities and to share hardware and software and data, so that users perceive it as a single, integrated computing service with a well-defined goal.
Goal continued - Distributed computing relies on inter-process communication, which involves the various layers of networking. Distributed computing helps create simple abstractions for these layers to facilitate program writing. Examples:
-
- TCP implements a reliable end-to-end communication channel,
- Media Access protocol used in Ethernet LAN or Wireless networks helps resolve network access conflict.
- Create a reliable channel between P and Q that are 10,000 miles away
- Geographic distribution of processes
- Resource sharing (example: P2P networks, grids)
- Computation speed up (as in a grid or cloud)
- Fault tolerance
Important challenges - Knowledge is local
- Clocks are not synchronized
- No globally shared address space
- Topology and routing : everything is dynamic
- Scalability: what is this
- Processes and links fail:
