Keywords: Wireless communications and ad hoc networks, distributed query processing, communication and energy optimisations, time triggered protocols. 1 Introduction With the advent of smart sensor devices, wireless sensor networks are an emerging research field [1,2]. Wireless sensor nodes form a wireless adhoc network
Users of wireless sensor networks (WSNs) often submit spatial window aggregation queries to obtain the summary information about a local area in the monitored region. We propose an adaptive spatial window aggregation query processing algorithm called ASWAP in this paper. It divides the query area into several disjoint sub–regions.

Query processing is one of the active research areas in wireless sensor networks. User queries in declarative forms are received at a central sink or base station, optimized and then disseminated among the sensor nodes, which process the queries and the results are sent back to the user ends for further processing.

Abstract—Wireless Sensor Networks (WSNs) are typically used to collect values of some phenomena in a monitored area. In many applications, users are interested in summaries of the observed data,, a histogram reflecting the distribution of the collected values. However, processing a histogram query efficiently on top of WSN is a topic that
