A Novel Adaptive Monitoring Compliance Design Pattern for Autonomic Computing Systems

Abstract

The need for adaptability in software is growing, driven in part by the emergence of pervasive and autonomic computing. In many cases, it is desirable to enhance existing programs with adaptive behavior, enabling them to execute effectively in dynamic environments. Increasingly, software systems should self-adapt to satisfy new requirements and environmental conditions that may arise after deployment. Due to their high complexity, adaptive programs are difficult to specify, design, verify, and validate. Moreover, the current lack of reusable design expertise that can be leveraged from one adaptive system to another further exacerbates the problem. In this paper we proposed an adaptive design pattern called adaptive sensor factory to make the monitoring infrastructure of the adaptive system more dynamic by fusing the sensor factory pattern, observer and strategy patterns. This pattern will determine the type of sensor that suits best for monitoring the client. We have applied it to a sample application which is monitoring compliant and makes use of this monitoring infrastructure.
