A Measurement-Based Path Loss Model for Mobile-to- Mobile Link Reliability Estimation

This paper shows results of narrowband path loss measurements in a typical urban mobile-to-mobile radio environment at 900 MHz band. The path loss exponent and the variance of the random variable modeling the effects of shadowing and fading are derived from real world measurements performed in an urban and rural area. These parameters can be used with a simple power law path loss model to predict reliable communication link for communication systems operating in a mobile-to-mobile environment, such as a cross-layer routing protocol design of mobile ad-hoc networks. The proposed method can be also used for path evaluation of multipath routing.
