This document outlines a project to improve security and efficiency in mobile computing networks. It discusses issues like limited physical security of wireless networks and constrained bandwidth. The project will use mobile agents to distribute tasks across nodes, reducing unnecessary data transmission loads. Mobile agents can migrate between nodes as needed to complete tasks, without requiring constant client connection. This helps prevent increased workloads from network expansion. The document also lists benefits like increased productivity and flexibility from mobile computing. It proposes a key management and access control method for mobile agents to enhance security and performance efficiency.

3. AIM: Efficient migration for mobile computing in
distributed networks and reducing security risks

4. INTRODUCTION
The radical evolution of computers, especially in hardware
(towards smaller size and weight, higher performance,
lower power consumption, lower cost) and communications
(wireless and satellite networks, cellular telephony, WANs,
INTERNET), has introduced the idea of mobile computing.
This means that users don't have to be tethered on
expensive wired workstations in order to exchange data. All
they need is mobile computers, that is portable computers
communicating via wireless networks.

5. STATEMENT OF PURPOSE
There are serious networkings and systems issues to be
solved before the full benefits of mobile computing systems
are realized in practice. One critical issue is security .
The networks have become complex and bulky. Large
networks increase workload which in turn increases net
dataflow. The heavy dataflow leads to a drop in work
efficiency.

6.  Our work on the security of mobile computing aims to
address the problems pertaining to the security of
information within the following three sub-areas of the
mobile environment:
 1. The security of information residing in the mobile units,
considering device constraints.
 2. The security of information as it travels 'over the air'
between mobile units and mobile support stations.
 3. The security of information within the rest network (wired
hosts).

7.  Because a wireless LAN signal is not limited to the physical
boundary of a building, potential exists for unauthorized
access to the network from personnel outside the intended
coverage area. Most security concerns arise from this aspect
of a WLANs and fall into the following basic categories:
 Limited Physical Security : Since there is no physical link
between the nodes of the wireless network and the access
point, the users transmit information through the “air” and
hence anyone within the radio range can easily intercept or
eavesdrop on the communication channels.

8. Constrained Network Bandwidth:
The use of wireless communication typically implies a lower
bandwidth than that of traditional wired networks.
Energy Constrained Mobile Hosts:
To support mobility and portability, mobile devices generally
obtain their energy through batteries or other exhaustive
means, hence they are considered as energy constrained mobile
hosts.

9. We use mobile agents to provide a paradigm for distributed
object computing and mobile objects.
 It can communicate and interact with other agents and the
distributed resource system on heterogeneous networks.
A mobile agent can also decide when to migrate, and which
nodes to access.
 After migrating to the desired host, the mobile agent resumes
the execution of previously broken off or awaiting tasks.

10.  On completing the task, the mobile agent returns the result
to the client.
 Therefore, the client need not be constantly connected to the
server. This not only saves a lot of unnecessary transmission
load, but also helps in the application of mobile calculation.
 With this kind of entrusted distributed network management
server, increased workload which is often brought on by
expansion of network can be prevented.

14. TOTAL BUDGET

15. Location flexibility
This has enabled user to work from anywhere as long as there is a
connection established. A user can work without being in a fixed position.
Saves Time
The time consumed or wasted by travelling from different locations or to
the office and back, have been slashed.
Enhanced Productivity
Productive nature has been boosted by the fact that a worker can simply
work efficiently and effectively from which ever location they see
comfortable and suitable.
Ease of research
Research has been made easier, since users will go to the field and search for
facts and feed them back to the system.
Entertainment
Video and audio recordings can now be streamed on the go using mobile
computing. It's easy to access a wide variety of movies, educational and
informative material.

16.  To resist potential security risks and enhance performance
efficiency in application, this study presents for mobile
agents an efficient key management and access control
method .
 In advanced networking research, issues on mobile agents
have always been popular interest. Effectively utilizing
resources over the Internet greatly enhances the efficiency of
an organization and economizes computational overhead.
With regard to practical concept, mobile agents can improve
the efficiency of the software in hardware.
