Performance evaluation of a mobile-floating agent scheme for wireless mobile computing and communications

This paper examines the feasibility and performance benefits of the introduction of the mobile-floating agent scheme in a mobile system. The principal contribution of this paper is to innovatively apply virtual memory concepts to mobile systems by deploying mobile-floating agents who de-couple services and resources from the underlying network and allow them to move around following their mobile users. The concept of mobile-floating agent with the notion of service mobility, service pre-assignment and resource pre-arrangement is evaluated. Detailed analysis and evaluation of these scheme in terms of latency reduction and increased system overhead versus mobility density with three different assignment algorithms are given. The performance results clearly indicate the feasibility and the performance gain of the proposed mobile-floating agent scheme
