We study delay-efficient data aggregation scheduling in wireless sensor networks subject to signal to interference-plus-noise ratio (SINR) constraints. We construct a routing tree and propose two scheduling algorithms that can generate collision-free link schedules for data aggregation. We prove that the delay of each algorithm is $(O(R+\Delta ))$ time slots, where $(R)$ and $(\Delta)$ are respectively...
Data aggregation is a primitive communication task in wireless sensor networks (WSNs). In this paper, we study designing data aggregation schedules under the Protocol Interference Model for answering queries. Given a network consisting of a set of nodes V distributed in a two-dimensional plane, we address different kinds of queries in this paper. First and foremost, we consider a single one-off query...
Efficient aggregation of data collected by sensors is crucial for a successful application of wireless sensor networks (WSNs). Both minimizing the energy cost and reducing the time duration (or called latency) of data aggregation have been extensively studied for WSNs. Algorithms with theoretical performance guarantees are only known under the protocol interference model, or graph-based interference...
