Analytical evaluation of blocking probability in a mobile radio system with directed retry
In this paper, the blocking probability in a cellular network implementing directed retry (DR) is analyzed as a function of the main characteristics of the scenario (the density of base stations), the propagation model (path loss and shadowing), and the speed of mobiles. The analytical approach allows the evaluation of the blocking probability as a function of the maximum number of cells that c...
متن کاملEstimation in cellular radio systems
The problem to track time-varying parameters in cellular radio systems is studied, and the focus is on estimation based only on the signals that are readily available. Previous work have demonstrated very good performance, but were relying on analog measurement that are not available. Most of the information is lost due to quantization and sampling at a rate that might be as low as 2 Hz (GSM ca...
متن کاملIEEE 802.11 packet delay-a finite retry limit analysis
The contribution of this paper is on the study of packet delays for the IEEE 802.11 wireless local area network DCF MAC protocol. A method is presented capable of taking into account retransmission delays with or without retry limits. We present an analytical model based on a Markov chain which allows us to derive closed form expressions for the packet delays, the probability of a packet being ...
متن کاملFast Channel Assignment in Cellular Radio Systems
This paper proposes a new algorithm using a nonpositive neural network model to solve channel assignment problems in arbitrary cellular mobile radio systems. Unlike traditional neural nets used in optimization problems, the proposed network is guaranteed to deliver valid solutions after every update and needs no parameter tuning. The power of the new method to solve this NP-complete problem wil...
متن کاملPower Control in Cellular Radio Systems
The primary goal of cellular radio systems is to provide communications services to a large number of mobile users. Due to the dramatic increase of this market, the available resources have to be utilized efficiently. Closedloop power control is considered as an important component in these resource management algorithms. Here, relevant aspects on power control are discussed, using an automatic...
