Path loss exponent estimation for wireless sensor network localization
The wireless received signal strength (RSS) based localization techniques have attracted significant research interest for their simplicity. The RSS based localization techniques can be divided into two categories: the distance estimation based and the RSS profiling based techniques. The path loss exponent (PLE) is a key parameter in the distance estimation based localization algorithms, where ...
متن کاملOnline Calibration of Path Loss Exponent in Wireless Sensor Networks
The path loss exponent (PLE) is a parameter indicating the rate at which the received signal strength (RSS) decreases with distance, and its value depends on the specific propagation environment. Path loss exponent estimation plays an important role in distance-based wireless sensor network localization, where distance is estimated from the RSS measurements. Path loss exponent estimation is als...
متن کاملRSS-based Localization in Wireless Sensor Networks with Unknown Transmit Power and Path Loss Exponent using SDP Relaxation
This paper addresses the problem of locating multiple target nodes from noisy received signal strength (RSS) measurements in wireless sensor networks (WSNs), for the case where the transmit power and the path loss exponent (PLE) are simultaneously unknown. According to the conventional path loss model, the maximum likelihood (ML) estimator is derived by solving the nonlinear and nonconvex least...

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 کاملPath Loss Exponent Estimation in a Large Field of Interferers
In wireless channels, the path loss exponent (PLE) has a strong impact on the quality of links, and hence, it needs to be accurately estimated for the efficient design and operation of wireless networks. In this paper, we address the problem of PLE estimation in large wireless networks, which is relevant to several important issues in networked communications such as localization, energy-effici...
