"... Even though the analyses in many wireless networking problems assume that the value of the path loss exponent (PLE) is known a priori, this is often not the case, and an accurate estimate is crucial for the study and design of wireless systems. In this paper, we address the problem of estimating the ..."

1Analysis of the Relation Between Fresnel Zone and Path Loss Exponent Based on Two-Ray Model
"... Abstract—In this letter, the underlying factor that leads to the change of path loss exponent n is investigated, using a reasonable and reliable indirect demonstration which is based on the simple two-ray model and a developed multi-ray model. It is found that the 1st Fresnel zone is the underlying ..."

Path Loss Exponent and User Velocity Dependent Variable Hysteresis Margin Based Call Handover Algorithm
"... With the use of picocells to meet the increased demand of traffic density, the mobile communication networks need to comply with greater number of call handover requests than the normal cells. As the probability of handover requests is directly proportional to the mobile velocity, the handover respo ..."

response should be made dependent on mobile velocity to avoid unwanted call termination and early handover for high and low velocity vehicles respectively. Due to the dependency of handover performance to path loss exponent, a variable hysteresis scheme has already been proposed. As the handover
Dynamic Path Loss Exponent Estimation in a Vehicular Network using Doppler Effect and Received Signal Strength
"... Abstract — Localization in Ad-hoc wireless sensor networks is one of the important and demanded fields in engineering research and industry. Among these networks, vehicular Ad-hoc network, VANET, with emerging applications like Intelligent Transport Systems is considered as the most challenging area ..."

The main drawback of RSS based ranging is its considerable inaccuracy which is mostly originated from uncertainty of the path loss exponent which has an exponential effect on distance measurement. Without knowing
