Abstract
Due to rapid advancements and developments in computing platforms, there is a tremendous growth in heterogeneous distributed systems involving mobile devices. In distributed systems, achieving better performance and efficient utilization of shared resources are dependent on appropriate load monitoring mechanisms. In large-scale distributed systems, performing load monitoring is a challenging task and, it effects in increasing response time degrading system performance. In this paper, we have developed and implemented mobile agent-based load monitoring system intended to large-scale distributed systems. Mobile agent based design is an attractive approach for load monitoring in large-scale distributed systems, because mobile agents are autonomous, goal-driven, reactive to environmental changes and, lightweight piece of program. In this paper, a detailed software architectural design for mobile agent based load monitoring system is presented. The design is based on a probabilistic normed estimation model and corresponding monitoring algorithms. The experimental evaluations and scalability analysis presented in this paper illustrate the behavior of agents and performance of the system under different load conditions. Moreover, a detailed qualitative as well as quantitative analysis of various mobile agent models are presented.
1. INTRODUCTION
A distributed system is the combination of independent nodes operating in a network and appears to the users as a single coherent system [6]. Distributed systems mean distributed processing in a shared environment to minimize computing time and to increase the overall performance. However, achieving better performance and reduction of computing time are subject to proper load balancing and load monitoring mechanisms [7, 31]. It means that, the overall processing load should be equally distributed among all the nodes with the proper load monitoring mechanism to avoid underload or overload conditions. In recent time, researchers have proposed that strict load balancing in a distributed system may not offer improved performance [34]. However, in general, it is observed that load balancing is an important factor in heterogeneous large-scale distributed systems to avoid overloading/underloading skews at nodes [32, 33]. In distributed systems, load monitoring mechanisms are used to monitor available computing nodes in a system [25]. Without load monitoring, it is difficult to employ load balancing approaches to distributed systems. In large-scale distributed systems, load monitoring by a system administrator is a very difficult task [7, 26]. Moreover, load monitor creates frequent intercommunication in distributed systems while collecting node information repeatedly [8].
