Wireless Sensor Networks (WSNs) are composed of autonomous and resource-constrained (power, sensing, radios, and processors) nodes. These networks are conceived to have a large number of nodes working on monitoring phenomena in an area. So, a major challenge for this networks is to provide solutions that maximize quality of service (QoS) requirements, such as coverage and data routing, and minimize...
Storing data on sensor nodes at a specified location is a useful technique for data-centric storage and management of location dependent data on wireless sensor networks. To decrease the cost of accessing these data, arranging replicas of data so that the distance between the consumer nodes and replica holder nodes decreases is desirable. Conventional schemes, however, are costly for updating the...
