A framework for creating and deploying mobile agents

a framework for creating mobile agents ## Deliverables 1)need an agent interface which defines the following methods abstract public class Agent { /** * The runtime calls `initialize()` exactly once -- * after the agent is created. * */ abstract public void initialize(); /** * The runtime calls `start()` whenever an agent must be * started. * */ abstract public void start(); /** * The runtime calls `stop()` whenever an agent must be * stopped -- either to transfer it, to store it, or to terminate it. * * An agent whose `stop()` method is called should * stop all computation, store any intermediate results, join all * active threads, and promptly return. * */ abstract public void stop(); /** * The runtime calls `conclude()` exactly once -- before * the agent is destroyed. * */ abstract public void conclude(); } 2)agents should be able to migrate between communicating hosts The communication goes as follows: 1. The remote host notifies the local host of its desire to transfer an agent by invoking the remote agent's `requestToSend()` method. 2. The local host marks the beginning of the transfer by invoking the remote host's `beginTransfer()` method. The remote host in turn invokes the agent's `stop()` method. When the `stop()` method returns, the agent is ready for transfer. 3. The local host gets the resource piece of the agent by invoking the remote host's `transferResource()` method. The remote host returns the resource piece as an array of bytes. 4. The local host gets the data piece of the agent by invoking the remote host's `transferData()` method. The remote host returns the data piece as an array of bytes. 5. The local host marks the end of the transfer by invoking the remote host's `endTransfer()` method. It then resurrects the agent by calling the agent's `start()` method here the resource means the instructions which agent should execute and data means snapshopt of agent state ## Platform java
