Journal ArticleDOI
TL;DR: A context-aware cross-layer (CACL) broadcast model that uses only contextual data available to the 802.11 MAC is presented and it is concluded that, for a wide range of network conditions, CACL offers superior reliability and throughput.

Journal ArticleDOI
TL;DR: It is observed that CACL strongly outperforms the 802.11 MAC at high posting rates and is used in conjunction with a controlled flooding routing protocol, Self-Balancing Supply/Demand (SBSD), to test three different road-based mobility levels.

TL;DR: This work proposes space and communication efficient schemes capable of correlating spatial dimension with different physical values and combines rank order statistics, regular sampling, and bitmap representation to trade-off precision vs. energy consumption.
Abstract: We address the problem of efficient in-network processing of hybrid spatial queries in Wireless Sensor Networks (WSN), where the data may correspond to different physical phenomena in different regions. We propose space and communication efficient schemes capable of correlating spatial dimension with different physical values. To trade-off (im)precision vs. energy consumption, the proposed schemes combine rank order statistics, regular sampling, and bitmap representation. We present a proof of concept implementation of the proposed methodology and quantify the benefits of our approach through simulations.
