Radio-frequency identification (RFID) readers are powered RF devices that communicate with tags (whether mobile or fixed) and read necessary information to be processed. A RFID tag is detected by an antenna. In a where the attached object such as vehicle, human, animal, more difficult detect than in case stationary object. Currently, deployment engineers researchers use trial-and-error approaches decide on best conditions of detection influence factors which affect detectability (detection...

Vehicular ad-hoc networks (VANETs) are highly mobile wireless ad hoc for vehicular safety and other commercial applications, whereby vehicles move non-randomly along roads while exchanging information with roadside infrastructures. Inter-vehicle communication (IVC) is achieved wirelessly using multihop communication, without access to fixed infrastructure. Rapid movement frequent topology changes cause repeated link breakages, increasing the packet loss rate. Geographical routing protocols...
