aggregate query processing in sensor networks

For monitoring queries that aggregate the observed values from a group of sensor nodes suggested the construction of a greedy aggregation tree that seeks to maximize the number of aggregated messages and minimize the amount of the transmitted data To accomplish this nodes may delay sending replies to a posed query in anticipation of replies from other queried nodes aggregate crusher used in dubai
