Design and Implementation of a Policy-based Management System for Data Reliability in Wireless Sensor Networks

In this paper, we describe the design and the implementation of a management system called SRM for controlling data reliability in Wireless Sensor Networks. SRM is based on a hierarchical management architecture and policy-based network management paradigm. SRM consists of four modules: a user policy specification module, an evaluation module, a decision making module and an action module. The interaction among these modules ensures that the network provides adequate information to the users while reducing energy consumption. To demonstrate the effectiveness of the management framework, we design a policy for balancing energy consumption and data reliability. Our experimental results show that SRM can meet the reliability requirements, and reduces energy consumption by up to 50% compared to the case of no management.
