A sensor network is modelled to a grid which is divided into many cells with each one containing a number of sensor nodes. There are three types of nodes in a network: BS, Aggregation Node (AN), and Member Node (MN). It is assumed that BS is trusted and has unlimited energy, computing resource, and storage capacity.

In-network processing, however, has been limited to systems where at most, simple aggregate queries are evaluated, the results of which are communicated to the outside world. There is currently little research into how the idea of in-network processing can be extended and implemented to allow more complex queries to be resolved within the network. This paper examines key applicative query ...

Query Privacy Preserving for Data Aggregation in Wireless ...

Wireless Sensor Networks (WSNs) are increasingly involved in many applications. However, communication overhead and energy efficiency of sensor nodes are the major concerns in WSNs. In addition, the broadcast communication mode of WSNs makes the network vulnerable to privacy disclosure when the sensor nodes are subject to malicious behaviours.

Aggregate Threshold Queries in Sensor Networks

Aggregate threshold queries are of particular importance in a wireless sensor environment, since they allow network-wide events to be detected, with a minimum expenditure of energy. Such network-wide events might include, for example, the variance in sensor readings exceeding a certain threshold. We present an efficient algorithm for implementing arbitrary aggregate threshold queries

Processing Multiple Aggregation Queries in Geo-Sensor Networks

Due to the expensive energy cost of communication in wireless sensor networks, a summary of readings (i.e., aggregated readings) is preferred over a collection of all individual sensor readings. This kind of queries that collect aggregated readings from sensors within a geographical area is called spatial aggregation query. In such queries, aggregate functions such as sum, count, average, max ...
