We study the problem of planning the motion of “data mules” for collecting the data from stationary sensor nodes in wireless sensor networks. Use of data mules significantly reduces energy consumption at sensor nodes compared to...
MCRT: Multichannel Real-Time Communications in Wireless Sensor Networks
Xiaorui Wang, Xiaodong Wang, Xing Fu, Guoliang Xing
Article No.: 2
As many radio chips used in today’s sensor mote hardware can work at different frequencies, several multichannel communication protocols have recently been proposed to improve network throughput and reduce packet loss for wireless sensor...
Spatiotemporal Models for Data-Anomaly Detection in Dynamic Environmental Monitoring Campaigns
Ethan W. Dereszynski, Thomas G. Dietterich
Article No.: 3
The ecological sciences have benefited greatly from recent advances in wireless sensor technologies. These technologies allow researchers to deploy networks of automated sensors, which can monitor a landscape at very fine temporal and spatial...
Hierarchical Spatial Gossip for Multiresolution Representations in Sensor Networks
Rik Sarkar, Xianjin Zhu, Jie Gao
Article No.: 4
In this article we propose a lightweight algorithm for constructing multiresolution data representations for sensor networks. At each sensor node u, we compute O(log n) aggregates about exponentially enlarging neighborhoods...
Recent work has shown that, despite the minimal information provided by a binary proximity sensor, a network of these sensors can provide remarkably good target tracking performance. In this article, we examine the performance of such a sensor...
Providing efficient data aggregation while preserving data privacy is a challenging problem in wireless sensor networks research. In this article, we present two privacy-preserving data aggregation schemes for additive aggregation functions, which...
Data Collection in Wireless Sensor Networks with Mobile Elements: A Survey
Mario Di Francesco, Sajal K. Das, Giuseppe Anastasi
Article No.: 7
Wireless sensor networks (WSNs) have emerged as an effective solution for a wide range of applications. Most of the traditional WSN architectures consist of static nodes which are densely deployed over a sensing area. Recently, several WSN...
Analysis of Deterministic Tracking of Multiple Objects Using a Binary Sensor Network
Yann Busnel, Leonardo Querzoni, Roberto Baldoni, Marin Bertier, Anne-Marie Kermarrec
Article No.: 8
Let consider a set of anonymous moving objects to be tracked in a binary sensor network. This article studies the problem of associating deterministically a track revealed by the sensor network with the trajectory of an unique anonymous object,...
