Characteristics of mobile agents: The following characteristics are typical of a mobile agent and its host:

An agent must have its own unique identity.
It must be able to determine what other agents are executing on the agent host (AH).
It must be able to determine what messages other agents accept and send.
An AH must allow agents to communicate with each other and itself.
It must allow multiple agents to coexist and execute simultaneously.
It must be able to negotiate the exchange of agents.
It must be able to freeze an executing agent and transfer it to another host.
It must be able to thaw an agent transferred from another and allow it to resume execution.
It must prevent agents from directly interfering with each other.

Mobile Agents:

An agent is “an independent software program, which runs on behalf of a network user”.
A mobile agent is a program that, once it is launched by a user, can travel from node to node autonomously, and can continue to function even if the user is disconnected from the network.

Properties

Autonomy:-Independent to user
Adaptive learning:-adaptive in environment
Mobility:-jumping from one node to another node
Rationality:-Do not divert from its goal.

Advantages - Reduction in network load - Overcome network latency - Async & autonomous execution - Fault tolerance

Disadvantages - Virus can be disguised as mobile agent - Security bug. - Async & autonomous execution - Mobile agent are not mature technology and most agent development tools are alpha or beta version.

Application: - Parallel computing. - Data collection. - E-commerce. - Mobile computing.

Advantages of Mobile Agents

They allow efficient and economical use of communication channels that may have low bandwidth, high latency, and may be error- prone. They enable the use of portable, low-cost, personal communications devices to perform complex tasks even when the device is disconnected from the network.
They allow asynchronous operations and true decentralization.

Disadvantages ● Security ● risk Virus-attack 13 Mobile-agent applications ● Information retrieval ● Monitoring Virtual market-place/ meeting room ● Shareware
