Error Control in Distributed Node Self-Localization

Error Control in Distributed Node Self-Localization

Location information of nodes in an ad hoc sensor network is essential to many tasks such as routing, cooperative sensing, and service delivery. Distributed node self-localization is lightweight and requires little communication overhead, but often suffers from the adverse effects of error propagation. Unlike other localization papers which focus on designing elaborate localization algorithms, ...

Beacon Node Placement for Minimal Localization Error

Beacon node placement, node-to-node measurement, and target node positioning are the three key steps for a localization process. However, compared with the other two steps, beacon node placement still lacks a comprehensive, systematic study in research literatures. To fill this gap, we address the Beacon Node Placment (BNP) problem that deploys beacon nodes for minimal localization error in thi...

Optimized Distributed Range-Based Node Localization in Wireless Sensor Networks

This paper proposes range-based distributed single-hop and scalable 3D node localization algorithm by using the application of Biogeography Based Optimization in anisotropic Wireless Sensor Networks (WSNs). In anisotropic networks, radiation patterns are not uniform. An anisotropic property of propagation media and heterogeneous properties (different battery backup statuses) of the devices are ...

Error Correcting Codes for Distributed Control

The problem of stabilizing an unstable plant over a noisy communication link is an increasingly important one that arises in applications of networked control systems. Although the work of Schulman and Sahai over the past two decades, and their development of the notions of “tree codes” and “anytime capacity”, provides the theoretical framework for studying such problems, there has been scant p...
