A Novel Range-free Localization Scheme for Wireless Sensor Networks
This paper present a low-cost yet effective localization scheme for the wireless sensor networks. There are many studies in the literature of locating the sensors in the wireless sensor networks. Most of them require either installing extra hardware or having a certain amount of sensor nodes with known positions. The localization scheme we propose in this paper is range-free, i.e., not requirin...
متن کاملEffective Range- Free Localization Scheme for Wireless Sensor Network
Location aware sensors can be used in many areas such as military and civilian applications. Wireless Sensor Networks help to identify the accurate location of the event. In this paper a cost effective schema for localization has been proposed. It uses two beacon nodes to identify the location of unknown nodes. It also uses flooding and estimating method to accurately identify the location of o...
متن کاملRange-Free Localization Schemes for Wireless Sensor Networks
Localization of nodes is one of the key issues of Wireless Sensor Network (WSN) that gained a wide attention in recent years. The existing localization techniques can be generally categorized into two types: range-based and range-free. Compared with rang-based schemes, the range-free schemes are more costeffective, because no additional ranging devices are needed. As a result, we focus our rese...
متن کاملRange Free Localization Schemes for Wireless Sensor Networks
Wireless sensor networks have become a hot research area due to their numerous applications in monitoring inaccessible areas, which are difficult to be monitored by conventional methods. A large number of wireless sensor network based applications are location dependent, where the sensed data is meaningless without accurate location of its origin. Some of these applications require highly accur...
متن کاملImprove range-free localization accuracy in wireless sensor network using DV-hop and zoning
In recent years, wireless sensor networks have drawn great attention. This type of network is composed of a large number of sensor nodes which are able to sense, process and communicate. Besides, they are used in various fields such as emergency relief in disasters, monitoring the environment, military affairs and etc. Sensor nodes collect environmental data by using their sensors and send them...
