Abstract

Event-based ad hoc query processing is one of the most important functions of wireless sensor networks. Data centric storage algorithm is carried out to solve the problem but the traditional algorithm neglects that events will last for a time. During this time, the relationship between the query frequency and the data production frequency will change, which is an important feature to affect the energy consumption of the event-based ad hoc query processing in sensor networks. In this paper, we propose an adaptive data transmission algorithm, which takes the relationship into account. Experiments shows that our adaptive algorithm can save more energy than the traditional data centric storage algorithm.
