“…Stanford University Interim (SUI) model was originally proposed by Stanford University as the propagation model for Multipoint Microwave Distribution Systems (MMDS) operating in the 2.5GHz to 2.7GHz bands [16]- [18]. But it was later adopted by the IEEE 802.16 working group as the propagation model for Fixed Wireless Access (FWA) systems operating in the 3.5GHz band [20]- [26].…”

“…〈P R (d 0 )〉 is the average path loss at reference distance d 0 , n is the path loss exponent, and Xσ is a zero mean log-normally distributed random variable with standard deviation σ [5]. The reference distance was set at 10 m. The parameters n and σ can be determined using linear regression of the path loss values against the log of normalized distance (d/d 0 ) in a minimum mean square error (MMSE) manner [7].…”

Large scale path loss measurements in sea port are presented. This investigation is useful before deploying Worldwide Interoperability for Microwave Access (WiMAX) equipments to provide last mile Broadband Wireless Access (BWA) for ships and boats in the sea port. Measurements were carried out at 5.8 GHz. Two-ray model fits measured large scale path loss reasonably well. When the distance is very large, the received signal was found to attenuate at the rate of more than double of that of the free space. The attenuation rate was found to depend on the antenna's height.

“…In CDMA-base networks, a RAKE receiver can collect signal energy from different paths. Hence, we assume that there is no fading, and the transmit power is attenuated only due to path loss with exponent α = 2.4 [13], [14]. The burst arrival at each node is a Poisson process.…”

An Interference Aware Distributed Resource Management Scheme for CDMA-Based Wireless Mesh Backbone

Abstract-In this paper, with a cross-layer design principle, we propose an interference aware distributed resource management scheme for a code-division multiple access (CDMA)-based wireless mesh backbone (consisting of a number of wireless routers at fixed sites). Specifically, benefiting from the fixed location of wireless routers, the power allocation is based on the length of the transmission path, so as to ensure a certain level of fairness among the routers. For a new call arrival, based on the maximum sustainable interference concept, each existing receiver (rather than the potential sender) estimates its experienced interference level under the hypothesis that the new call is admitted. If the interference is not tolerable, the existing receiver rejects the new call by sending a blocking-signal. The main advantages of our proposed scheme are the low control message overhead for easy implementation, and the accurate interference estimation. Simulation results are presented to evaluate the performance of our scheme.Index Terms-CDMA, cross-layer design, resource management, wireless mesh networks.
