Localization is one of the important for robots, this paper propose robot localization methods based on WSNs(wireless sensor network). In the WSNs, robots act as a mobile nodes, so the location method for WSNs' nodes can be used for robots. Range-based location method and range-free location method are discussed in detail in the paper.
This paper proposed an efficient mapping system which has been implemented on a mobile cart equipped with a laser range sensor and dead reckoning sensors. The practical mapping system to generate accurate maps in unknown environments is one of the main requirements for mobile robots. The mapping system is divided into hardware and software parts. The hardware part, mobile cart, consisted of two encoders,...
The accurate localization of sensor nodes in a mobile robotic sensor network is important in many surveillance applications. Based on our previous work in sensor localization, this paper introduces a mobility assisted localization approach guided by network rigidity for mobile robotic sensor networks. The rigidity test of a network is based on a pebble game algorithm, that decides whether the network...
For a set of mobile sensor network, a precise localization is required in order to maximize the utilization of mobile sensor network. As well, mobile robots also need a precise localization mechanism for the same reason. In this paper, we showed a combination of various localization mechanisms. Localization can be classified in three big categories: long distance localization with low accuracy, medium...
There exist several application scenarios of mobile ad hoc networks (MANET) in which the nodes need to locate a target or surround it. Severe resource constraints in MANETs call for energy efficient target localization and collaborative navigation. Centralized control of MANET nodes is not an attractive solution due to its high network utilization that can result in congestions and delays. In nature,...
In this paper, algorithms for navigating a mobile node through wireless sensor networks are presented. The mobile node can navigate without the need for a map, compass, or GPS module while interacting with neighboring sensor nodes. Two navigation algorithms are proposed in this paper: the first uses the distance between the mobile node and each sensor node and the second uses the metric calculated...
Optimizing energy consumption for extending the lifetime in wireless sensor networks is of dominant importance. Groups of autonomous robots and unmanned aerial vehicles (UAVs) acting as mobile data collectors are utilized to minimize the energy expenditure of the sensor nodes by approaching the sensors and collecting their buffers via single hop communication, rather than using multihop routing to...
