Ease of dynamically controlling access to a complex information source? Orders Wireless Network HQ Wired News Specs BGW Application: Soldiers in the Field Lessons Learned Mobile code is an effective and efficient infrastructure for developing military command-and-control applications. TCP/IP is inappropriate for the wireless network. Applications need to make decisions based on the current network situation. Network sensing and prediction is essential for best performance. Bandwidth conservation, power control, and network clustering are critical even in “high-bandwidth” wireless networks. Key Technologies Mobile code Ad-hoc wireless networking, network sensing, and network prediction Example Scenario: Urban Peacekeeping Our Peacekeepers NATO peacekeeping force in capital city Laptop 200 MHz Pentium II Linux Lucent 802.11 cards 2 Mb/s 150-300 meters GPS antenna Lessons Learned: Motorola ONCORE GPS unit Aggressor state: New Hampshire Our focus is software. The software can be used on many different hardware platforms (e.g., wearable computers). Breakaway province: Hanover Dartmouth
