Optimizing Data Replication for Expanding Ring-based Queries in Wireless Sensor Networks


We consider the problem of optimizing the number of replicas for event information in wireless sensor networks, when queries are disseminated using expanding rings. We obtain closed-form approximations for the expected energy costs of search, as well as replication. Using these expressions we derive the replication strategies that minimize the expected… (More)
