In Wireless Sensor Networks (WSNs), sensor nodes power consumption is the main challenge. Emerging in-network aggregation techniques are increasingly being sought to overcome this constraint and to save precious energy. WSN applications require spatially dense deployment of sensor nodes to achieve full coverage. As a result, sensors observations have spatial correlation. Rate Distortion theory with...
Extending the lifetime of wireless sensor networks remains the most challenging and demanding requirement that impedes large-scale deployments. The basic operation in WSNs is the systematic gathering and transmission of sensed data to a base station for further processing. During data gathering, the amount of data can be large sometimes, due to redundant data combined from different sensing nodes...
Inside the grouping process of sensor networks each node must decide what local group it is going to be a part of for data aggregation and dissemination. We look at how to form the most likely groups using agent centric methods based on the similarity to other nodes in the network and evaluate methods based on clustering, thresholding and fuzzy logic. The methods use simple scores that represent the...
