We develop a novel auction-based algorithm to allow users to fairly compete for a wireless fading channel. We use the second-price auction mechanism whereby user bids for the channel, during each time-slot, based on the fade state of the channel, and the user that makes the higher bid wins use of the channel by paying the second highest bid. Under the assumption that each user has a limited bud...

OF THE DISSERTATION Service Outage Based Adaptive Transmission in Fading Channels by Jianghong Luo Dissertation Director: Prof. Roy Yates, Prof. Predrag Spasojević The service outage based allocation problem explores variable rate transmission schemes and combines the concepts of ergodic capacity and outage capacity for fading channels. The ergodic capacity determines the maximum achievable rat...

AbsnaciIn this paper, we analyzed the performance of dynamic resource allocation with channel de-allocation and buffering in cellular networks. Buffers are applied for data traffic to reduce the packet loss probability while channel de-allocation is exploited to reduce the voice blocking probability. The results show that while buffering data traffic can reduce the packet loss probability, it h...

This paper presents two strategies for joint adaptive modulation and coding (AMC) techniques. The first strategy is based on the fixed sub-channel (FS)-AMC allocation, which exploits the coherence bandwidth of the wireless channel to divide the transmitted frame into independent sub-channels that correspond to the channel coherence bandwidth as well as selecting the optimal modulation and codin...

INTRODUCTION In this lecture, we continue on radio resource management in wireless networks, and are focused on the resource allocation algorithm. Firstly, we discuss the goal of optimum regarding resource allocation, based on which we define the assignment failure rate and the instantaneous capacity of a wireless system. We also discuss two kinds of channel allocation: Fixed Channel Allocation...

Received Nov 19, 2017 Revised Jan 23, 2018 Accepted Feb 19, 2018 Long Term Evolution (LTE) is the technology used in modern third and fourth generation mobile wireless cellular networks. Due to the presence of large number of users, mobility and varying channel conditions, proper resource allocation is essential to provide a good user experience and improve the system throughput.

We present an analytical model to compute the blocking probability in channelized cellular systems with dynamic channel allocation. We model the channel occupancy in a cell by a two-dimensional (2-D) Markov chain, which can be solved to obtain the blocking probability in each cell. We apply our analytical model to linear highway systems with and without lognormal shadowing and then extend it to...

In this paper, we consider the problem of rate and power allocation in a multiple-access channel (MAC). Our objective is to obtain rate and power allocation policies that maximize a general concave utility function of average transmission rates on the information-theoretic capacity region of the MAC without using queue-length information. First, we address the utility maximization problem in a ...

Cooperative communication has characteristics of offering spatial diversity by employing relays to improve communication efficiency significantly in wireless networks. One of the important design issues in cooperative communication is to optimize the power allocated to source and relay. The problem of allocating optimal power significantly affects the performance of the network as more power ra...
