Underground coal mine monitoring with wireless sensor networks
Mo Li, Yunhao Liu
Article No.: 10
Environment monitoring in coal mines is an important application of wireless sensor networks (WSNs) that has commercial potential. We discuss the design of a Structure-Aware Self-Adaptive WSN system, SASA. By regulating the mesh sensor network...
Distributed localization for anisotropic sensor networks
Hyuk Lim, Jennifer C. Hou
Article No.: 11
In this article, we address the issue of localization in anisotropic sensor networks. Anisotropic networks differ from isotropic networks in that they possess properties that vary according to the direction of measurement. Anisotropic...
Segmenting a sensor field: Algorithms and applications in network design
Xianjin Zhu, Rik Sarkar, Jie Gao
Article No.: 12
The diversity of the deployment settings of sensor networks is naturally inherited from the diversity of geographical features of the embedded environment, and greatly influences network design. Many sensor network protocols in the literature...
Security model and framework for information aggregation in sensor networks
Mark Manulis, Jörg Schwenk
Article No.: 13
Information aggregation is an important operation in wireless sensor networks (WSNs) executed for the purpose of monitoring and reporting environmental data. Due to the performance constraints of sensor nodes the in-network form of the aggregation...
SGF: A state-free gradient-based forwarding protocol for wireless sensor networks
Pei Huang, Hongyang Chen, Guoliang Xing, Yongdong Tan
Article No.: 14
Limitation on available resources is a major challenge in wireless sensor networks. Due to high rates of unexpected node/link failures, robust data delivery through multiple hops also becomes a critical issue. In this article we present a...
Trail: A distance-sensitive sensor network service for distributed object tracking
Vinodkrishnan Kulathumani, Anish Arora, Mukundan Sridharan, Murat Demirbas
Article No.: 15
Distributed observation and control of mobile objects via static wireless sensors demands timely information in a distance-sensitive manner: Information about closer objects is required more often and more quickly than that of farther...
Energy-efficient multihop reprogramming for sensor networks
Sandeep Kulkarni, Limin Wang
Article No.: 16
Reprogramming of sensor networks is an important and challenging problem, as it is often necessary to reprogram the sensors in place. In this article, we propose MNP, a multihop reprogramming service designed for sensor networks. One of the...
Path coverage by a sensor field: The nonhomogeneous case
Pallavi Manohar, S. Sundhar Ram, D. Manjunath
Article No.: 17
We analyze the statistical properties of the coverage of a one-dimensional path induced by a two-dimensional nonhomogeneous random sensor network. Sensor locations form a nonhomogeneous Poisson process and sensing area for the sensors are circles...
Analytic evaluation of target detection in heterogeneous wireless sensor networks
Loukas Lazos, Radha Poovendran, James A. Ritcey
Article No.: 18
In this article, we address the problem of target detection in Wireless Sensor Networks (WSNs). We formulate the target detection problem as a line-set intersection problem and use integral geometry to analytically characterize the probability of...
