摘要: Worldwide applications exist in an environment that is inherently distributed, dynamic, heterogeneous, insecure, unreliable, and unpredictable. In particular, the latency bandwidth of network connections varies tremendously from place to time time, particularly when considering wireless networks, mobile devices, satellite connections. Applications this must be able adapt different changing conditions. We believe transportable autonomous agents provide excellent mechanism for construction such applications. describe our prototype transportable-agent system several
