Reducing resource consumption in WSN in the event of a node failure

The recent years have seen an increase in the implementation of Wireless Sensor Networks (WSNs) in various monitoring and management applications. Deployment of a WSN for critical management or monitoring applications in locations with poor accessibility requires the WSN to be autonomous and sustainable. In this paper, a framework based state implementation within the sensor node is discussed that assesses the resources available to the node and detect the depletion nature of the resources. The successful switching between the states is based on the resource assessment. Various management techniques like power, data and communication management are applied so that the total depletion is realised gradually rather than abruptly. Results of simulation with power management feature of the framework and how it influences the extension of the battery life of a sensor node are presented.
