....All of them agree on the idea of placing processes in the network infrastructure, rather than inserting them into end servers, with the goal of optimizing operating costs and favouring asynchronous client server interactions. Concerning works that use agents, we highlight [CG95,HS97,SM98,CJFC] The main idea behind them is that wireless devices send agents to the xed network, where they work autonomously to carry out their tasks, and once they nish, they return to the wireless devices. Finally, among the works that, as in our case, use agent and proxies we mention ....

....can be formulated and implemented through mobile agents. Finally, the actual content of a transmission can be a mobile agent an object that can make decisions about routing or disposal without having to refer back to the original sender, who may or may not be on line at any particular instant [6]. Such a mobile agent could also carry along code to implement specific protocols which might not be available in the addressee s environment. A detailed discussion of this aspect is outside the scope of this paper. Mobile agents satisfy both requirements mentioned above: They improve network ....

....who are familiar with wireless and wired network, and communication protocols, mobility often implies physical mobility, the mobility in the real world. The application domain of physical mobility includes PDA (personal digital assistants) using GPS [66] support for laptop and notebook computers [38, 53, 54, 57], and reduction in energy consumption [50, 67] On the other hand, for those who familiar with operating system and programming languages, mobility often implies software mobility. This is the reason why Luca Cardelli proposed that the former form of 13 14 CHAPTER 1. INTRODUCTION mobility should ....

....our model comprises from a library of object classes which will implement the necessary basic functions. We will then analyse some of the mechanisms used to guarantee the ACID properties in a distributed environment, assessing their functions in relation to the specific properties of mobile agents [1, 4, 5]. The paper is structured as follows. Section 2 illustrates the distributed mobile agent transaction model proposed; Section 3 presents a model of the transactional environment, illustrating the entities involved in a distributed transaction and their behaviour; Section 4 analyses the impact on a ....

.... Mobile Agent Mobile Agent Figure 2: Modular Composition of the Environment These functions have to be implemented taking into account that a distributed transaction is not based on client server semantics but on mobile agents and therefore possesses all the latter s characteristics [1, 2, 5, 4]. As we will see in Section 4, these features can affect the protocols for concurrency control, commitment, fault detection and fault recovery, thus requiring accurate analysis and re elaboration as compared with the client server model. The Mobile Agent Execution Framework is the environment ....

A scheme based on mobile code The plug and play scheme shown in Fig. 4, which is based on mobile code assumes that an infrastructure for mobile agents [5] is in place. For example, the Java based Mobile Code Toolkit, MCT is a framework implemented by Carleton University s Perpetuum Mobile Procura group [11] The Open Management Group s Mobile Agent Framework (MAF) is an effort to establish a standard that would ensure interoperability of mobility ....

(QRPC) and stable logging of object state to support fault recovery; although Rover is primarily used in disconnected or partially connected client server computing, it can be used with some effort as a more general mobile agent system [JdT 95, JTK97, JK96] The Smart Messages system [HCS97] associates one or more reactive planners with each application level message; the reactive planners are activated whenever the message is queued somewhere within the network and allow the message to control its own routing, filtering and error recovery.
