State Dependent Attempt Rate Modeling of Single Cell IEEE~802.11 WLANs with Homogeneous Nodes and Poisson Packet Arrivals
Analytical models for IEEE 802.11-based WLANs are invariably based on approximations, such as the well-known decoupling approximation proposed by Bianchi for modeling single cell WLANs consisting of saturated nodes. In this paper, we provide a new approach to model the situation when the nodes are not saturated. We study a State Dependent Attempt Rate (SDAR) approximation to model M queues (one...
متن کاملCell-Level Modeling of IEEE 802.11 WLANs
We develop a scalable cell-level analytical model for multi-cell infrastructure IEEE 802.11 WLANs under a so-called Pairwise Binary Dependence (PBD) condition. The PBD condition is a geometric property under which the relative locations of the nodes inside a cell do not matter and the network is free of hidden nodes. For the cases of saturated nodes and TCP-controlled long-file downloads, we pr...
متن کاملState-dependent Control of a Single Stage Hybrid System with Poisson Arrivals
We consider a single-stage hybrid manufacturing system where jobs arrive according to a Poisson process. These jobs undergo a deterministic process which is controllable. We define a stochastic hybrid optimal control problem and decompose it hierarchically to a lower-level and a higher-level problem. The lower-level problem is a deterministic optimal control problem solved by means of calculus ...
متن کاملService Differentiation of IEEE 802.11 Wireless LAN with Poisson Packet Arrivals
We propose two analytical models using discrete-time Markov chain to compute the throughput and delay for IEEE 802.11 WLAN. Instead of assuming that there is always a frame at each station ready to send, we consider the more realistic Poisson arrival traffic model. Although we study only the RTS/CTS access mechanism, the analysis can be easily extended to the basic access mechanism. Furthermore...
متن کاملPerformance Evaluation of Three Node Tandem Communication Network Model with feedback for first two nodes having Homogeneous Poisson arrivals
Abstract In this paper we introduced the three node communication model with feedback for the first and second nodes assuming where every arrival makes homogeneous Poisson process one of the possible decisions by forwarding to the next node or to return back to nodes without taking service. Assuming such a decision to be entirely governed by the queue at the instant of the arrival, the transien...
