Self-Organizing Distributed Sensor Networks
Advances in CMOS IC and micro electrical-mechanical systems (MEMS) technology are enabling construction of low-cost building blocks each of which incorporates sensing, signal processing, and wireless communications. Collections of these integrated microsensor nodes may be formed into sensor networks in a wide variety of ways, with characteristics that depend on the specific application – the to...
متن کاملREQUEST: Region-Based Query Processing in Sensor Networks
In wireless sensor networks, node failures occur frequently. The effects of these failures can be reduced by using aggregated values of small groups of sensors instead of the values of individual sensors. However, most existing works have focused on computing the aggregation of all the nodes without grouping. Only a few approaches proposed the processing of grouped aggregate queries. However, s...
متن کاملA Distributed Energy Efficient Query Processing in Self-Organized Wireless Sensor Networks
Spatial query execution is an essential functionality of a sensor network. Redundancy within a sensor network can be exploited to reduce the communication cost incurred in execution of such queries. Any reduction in communication cost would result in an efficient use of battery energy, which is very limited in sensors. One approach to reduce the communication cost of a query is to self-organize...
متن کاملDistributed Spatial Skyline Query Processing in Wireless Sensor Networks
Spatial skyline queries can be used in wireless sensor networks for collaborative positioning of multiple objects. However, designing a distributed spatial skyline algorithm in resource constrained wireless environments introduces several research challenges: how to distribute the computation of distances to multiple events in order to compute the skylines efficiently, accurately, quickly, prog...
متن کاملA Distributed Query Protocol in Wireless Sensor Networks
In wireless sensor networks, query execution over a specific geographical region is an essential function for collecting sensed data. However, sensor nodes deployed in sensor networks have limited battery power. Hence, the minimum number of connected sensor nodes that covers the queried region in a sensor network must be determined. This paper proposes an efficient distributed protocol to find ...
