Fault Repair Framework for Mobile Sensor Networks

In this paper, we propose a framework for fault repair in mobile sensor networks. A hierarchical structure which consists of replacement module, management policy module, knowledge module, decision making module, and evaluation module is adopted. We also propose a solution for faulty sensor replacement problem. Through the numerical results, we show that our algorithm is more efficient and achieves higher energy savings than the greedy approach to sensor replacement. We believe that the problem of faulty sensor nodes can be solved efficiently through the cooperation and communication across different modules, such as evaluation decision making, knowledge management, and replacement
