Over the past decade, wireless sensor networks have advanced in terms of hardware design, communication protocols, resource efficiency, and other aspects. Recently, there has been growing interest in mobile wireless sensor networks, and several small-profile sensing devices that are able to control their own movement have already been developed. Unfortunately, resource constraints inhibit the use...
As complex and powerful systems, mobile robots can be used to cooperate with WSNs, whose nodes have restricted resource. Considering the vulnerability of traditional architecture for robot cooperated sensor networks deployment and perception with respect to adaptability and expandability, an original concept of HEDPA, which means hierarchical expanding deployment and perception architecture, is proposed...
Localization is a fundamental problem in wireless sensor networks (WSN). Many applications of WSN and middleware such as router require the sensor nodes to obtain their locations. Most existing localization algorithms use some mobile anchor nodes (e.g., equipped with GPS) to transmit beacons with their own coordinates for localizing other nodes. These algorithms do not need too much cost but obtain...
