Wireless sensor network localization techniques
Wireless sensor network localization is an important area that attracted significant research interest. This interest is expected to grow further with the proliferation of wireless sensor network applications. This paper provides an overview of the measurement techniques in sensor network localization and the one-hop localization algorithms based on these measurements. A detailed investigation ...
متن کاملLocalization algorithm techniques for sensor node in wireless sensor network
Localization is a way to determine the position of sensor nodes. It is very important to know about the location of data. This information can be obtained using localization technique in wireless sensor networks. Acombination of distance and direction measurement techniques introduced to estimate ranges not require any hardware and its cost effectiveness as compare to rangebased algorithm techn...
متن کاملGenetic Algorithm for Wireless Sensor Network With Localization Based Techniques
In wireless sensor network nodes position estimation in space is known as localization. Node localization in wireless sensor network is important for many applications and to find the position with Received Signal Strength Indicator requires a number of anchor nodes. However the estimation of distance from signal strength decay in not very accurate especially in time varying environmental condi...
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...
متن کاملWireless Sensor Network Localization Research
DV-Hop algorithm is one of the important range-free localization algorithms. It performs better in isotropic density senor networks, however, it brings larger location errors in random distributed networks. According to the localization principle of the DV-Hop algorithm, this paper improves the estimation of average single hop distance by using the Least Equal Square Error, and revises the esti...
