Achieving Optimal Throughput Utility and Low Delay With CSMA-Like Algorithms: A Virtual Multichannel Approach

Stability and throughput improvement for multichannel CSMA and CSMA/CD protocols with optimal bandwidth allocation

A Distributed Throughput-Optimal CSMA/CA

This paper addresses a distributed throughputoptimal CSMA/CA for wireless ad hoc networks, which is called the preemptive CSMA/CA. It achieves the optimality in a completely distributed fashion, even with discrete backoff time, non-zero carrier sense delay and data packet collisions. The algorithm is derived from the extension of Q-CSMA by Ni, Bo and Srikant to include collisions and is similar...

Energy Efficient and Throughput Optimal CSMA Scheme

Carrier Sense Multiple Access (CSMA) is widely used as a Medium Access Control (MAC) in wireless networks thanks to its simplicity and distributive nature. This motivated researchers to find CSMA schemes that achieves throughput optimality. In 2008, it has been shown that even simple CSMAtype algorithms is able to achieve optimality in terms of throughput and has been given the name ”adaptive” ...

Achieving Service Differentiation in 802.11e WLANs using p-Persistent CSMA Throughput/Delay Analysis

There is a growing need for quality of service (QoS) provisioning over 802.11 wireless local area networks. The 802.11e amendment addresses this need by allowing for traffic to be given different priority assignments. This can allow for QoS to be provided by service differentiation. In this paper we provide a simple throughput/delay analysis for p-persistent CSMA which can be used as an analysi...

a benchmarking approach to optimal asset allocation for insurers and pension funds

uncertainty in the financial market will be driven by underlying brownian motions, while the assets are assumed to be general stochastic processes adapted to the filtration of the brownian motions. the goal of this study is to calculate the accumulated wealth in order to optimize the expected terminal value using a suitable utility function. this thesis introduced the lim-wong’s benchmark fun...
