In wireless ad hoc and sensor networks, localization is a fundamental service to provide location information for those nodes without GPS units. In this paper, we use a simple yet effective proximity measure, called Regulated Neighborhood Distance (RND), to measure the closeness between two neighboring nodes based on their neighbors' numbers. Furthermore, we propose a RND-based localization algorithm,...
In wireless communications, localization has attracted attention from many researchers. Most of the researches focus on isotropic topologies, but in practical scenarios, wireless ad-hoc networks usually have irregular shapes (anisotropic topologies). For anisotropic topologies, many localization algorithms have failed to estimate the location of nodes. This paper proposes a new algorithm based on...
The accuracy of localization is a significant criterion to evaluate the practical utility of localization algorithm in wireless sensor networks. By analyzing the impact of the network topology on the position accuracy of representative localization algorithms, in this paper, we proposed a novel sequential chain directional transmission-based localization algorithm (SCDTLA), which uses the topology...
In many applications of Wireless Sensor Networks (WSN), it is crucial to know the location of sensor nodes. Although several methods have been proposed, most of them have poor performance in irregularly shaped networks. MDS-MAP is one of the localization methods based on multidimensional scaling (MDS) technique. It uses the connectivity information to derive the location of the nodes in the network...
Wireless communication is susceptible to radio interference and jamming attacks, which prevent the reception of communications. Most existing anti-jamming work does not consider the location information of radio interferers and jammers. However, this information can provide important insights for networks to manage its resource and to defend against radio interference. In this paper, we explore methods...
