“…The migration of MA is associated with different movement costs viz, transmission time, round trip time, number of hops, etc. MA research evolved over the past few years from the creation of many monolithic MA systems (MASs), often with similar characteristics and built by research groups spread all over the world for optimization and better understanding of specific agent issues [3,4] . To improve the performance of MAs means to optimize their paths on the network.…”

“…Furtermore, the agent uses a path through a network based upon known infrastructure characteristics (QoS). An agent optimizes its transmission between Agent hosts (AHs) [4] with the help of several migration strategies described in [5] .…”

“…Other areas where MAs are seen as offering potential advantages-wireless or mobile computing [3,4] dynamic deployment of code, thin clients or resource limited devices, personal assistants and MA-based parallel processing [5,9] . The idea of using MA in load balancing has been floating around for sometime in homogeneous telecommunication networks because traditional load balancing approaches are implemented based on message passing paradigm [1,10] .…”

Distributed Dynamic load balancing (DDLB) is an important system function destined to distribute workload among available processors to improve throughput and/or execution times of parallel computer in Cluster Computing. Instead of balancing the load in cluster by process migration, or by moving an entire process to a less loaded computer, we make an attempt to balance load by splitting processes into separate jobs and then balance them to nodes. In order to get target, we use mobile agent (MA) to distribute load among nodes in a cluster. In this study, a multi-agent framework for load balancing in heterogeneous cluster is given. Total load on node is calculated using queue length which is measured as the total number of processes in queue. We introduce types of agents along with policies needed to meet the requirements of the proposed load-balancing. Different metrics are used to compare load balancing mechanism with the existing message passing technology. The experiment is carried out on cluster of PC's divided into multiple LAN's using PMADE (Platform for Mobile agent distribution and execution). Preliminary experimental results demonstrated that the proposed framework is effective than the existing ones.

“…Such computers, termed walkstations Imielinski92] have the attraction of allowing users to access their computing environments from wherever they happen to be. Since computing environments are becoming inherently distributed, and walkstations are expected to make great use of network provided services, wireless connectivity between walkstations and the static network via base stations has become important.…”

In recent y ears small, completely portable computers have become available on the marketplace. There is demand for such computers, termed walkstations, to access network services while retaining their mobility, a n d t o operate e ectively in a wide range of conditions. Future o ce environments are expected to support wireless networks with bandwidths which are several orders of magnitude greater than are available outdoors. In such e n vironments, there will be powerful compute servers available for a walkstation's use.This dissertation describes a novel architecture called Notus and its supportfor applications operating in a mobile environment. The concept of the traded hando is introduced, where applications are able to participate in the hando process, rebuilding connections to the most appropriate service. This is expected to bene t walkstations which roam over large distances, where connections to servers would otherwise be strained, and also between heterogeneous networks where cooperation between the networks in performing a hando might be problematic. It is also proposed in this dissertation that applications could bene t from the ability to migrate onto compute servers as a walkstation moves into the o ce environment. This enables both the walkstation to conserve its own resources, and applications to improve the service provided to the end user. Finally, b y i n terleaving a traded hando with the migration process, it is possible for a migrating application to easily rebuild its connections as it moves to a new host.The Notus architecture has beenimplemented, including a traded hando service, and a new application migration service. The new application migration service was designed since existing application migration services are unsuited to mobile environments and it enables applications to migrate between heterogeneous hosts with little disruption. Applications which use the service are written in a standard, compiled language, and normal running applications suffer little overhead. A n umber of existing applications which a r e representative of a walkstation's interactive desk-top environment have beenadapted to use the Notus architecture, and are evaluated.In summary, this work describes how mobility awareness and the support from appropriate tools, can enable walkstation applications to better adapt to a changing mobile environment, particularly when the walkstation is carried between di erent n e t work types or over great distances.

“…For simplicity and generality, we will use the terms Mobile Unit (MU) for the users and their portable computing unit, Mobile Support Station (MSS) for the stations which maintain communications with the mobile units and Fixed Host for the other nodes connected to the mobile support stations [1].

During the last decade the decrease in the size of computing machinery, coupled with the increase in their computing power has lend to the development of the concept of mobile computing. Effects of this new vision is currently evident in the flourishing numbers of mobile telephones and portable computing units. In this paper we investigate some issues concerning the security of mobile computing systems, within the framework of the categories of mobility, disconnection, data access modes and scale of operation (Imielinski & Badrinath, 1993). In contrast to previous works which concentrate on security in wireless communications, we focus on the security of interactions which are built upon the underlying wireless communications medium. Some conclusions are presented on the future directions for security research in mobile computing systems.
