Cooperative Communication and QoS in Infrastructure WLANs
(2018-05-08)IEEE 802.11 wireless LANs operating in the infrastructure mode are extremely popular and have seen widespread deployment because of their convenience and cost efficiency. A large number of research studies have investigated ... -
Cooperative Communication In Store And Forward Wireless Networks Using Rateless Codes
(2013-08-30)In this thesis, we consider a cooperative relay-assisted communication system that uses rateless codes. When multiple relays are present, the relay with the highest channel gain to the source is the first to successfully ... -
Distributed Algorithms for Power Allocation Games on Gaussian Interference Channels
(2017-09-20)We consider a wireless communication system in which there are N transmitter-receiver pairs and each transmitter wants to communicate with its corresponding receiver. This is modelled as an interference channel. We propose ... -
Distributed Coding For Wireless Sensor Networks

Distributed Joint Source-Channel Coding For Multiple Access Channels
(2010-12-31)We consider the transmission of correlated sources over a multiple access channel(MAC). Multiple access channels are important building blocks in many practical communication systems, e.g., local area networks(LAN), cellular ... -
Information Rates over Point-to-Point and Multi-user Wireless Channels with Energy and Delay Constraints
In this thesis, we consider communication systems having energy, delay and reliability constraints. We characterize optimal communication rates achievable over these systems. First we consider point-to-point communication ... -
Modelling and Performance Analysis of New Coolstreaming for P2P IPTV
(2018-02-23)Peer to peer networks are becoming increasingly popular among Internet users as the downloading peers share the storage and upload bandwidth load of the system. This makes it possible for a large number of users to share ... -
On Design and Analysis of Energy Efficient Wireless Networks with QoS
(2018-06-13)We consider optimal power allocation policies for a single server, multiuser wireless communication system. The transmission channel may experience multipath fading. We obtain very efficient, low computational complexity ... -
Packet Scheduling on the Wireless Channel
(2017-12-07)Scheduling has always been an indispensable part of resource allocation in wireless networks. Accurate information about channel-state is assumed as a modeling simplification. However, in a real-life network ,e.g., Long ... -
Providing QoS To Real-time And Data Applications In 3G Wireless Systems
(2010-07-29)In this thesis we address the problem of providing end-to-end quality of service (QoS) to real-time and data connections in a third generation (3G) cellular network based on the Universal Mobile Telecommunication System ... -
Resource Allocation in Femtocells via Game Theory
(2018-08-14)Most of the cellular tra c (voice and data) is generated indoors. Due to attenuation from walls, quality of service (QoS) of di erent applications degrades for indoor tra c. Thus in order to provide QoS for such users the ... -
Robust Nonparametric Sequential Distributed Spectrum Sensing under EMI and Fading
(2018-07-16)Opportunistic use of unused spectrum could efficiently be carried out using the paradigm of Cognitive Radio (CR). A spectrum remains idle when the primary user (licensee) is not using it. The secondary nodes detect this ... -
Sequential Detection Based Cooperative Spectrum Sensing Algorithms For Cognitive Radio
(2011-07-11)Cognitive radios are the radios which use spectrum licensed to other users. For this, they perform Radio Environment Analysis, identify the Spectral holes and then operate in those holes. We consider the problem of Spectrum ... -
Spectrum Sensing in Cognitive Radios using Distributed Sequential Detection
(2018-03-17)Cognitive Radios are emerging communication systems which efficiently utilize the unused licensed radio spectrum called spectral holes. They run Spectrum sensing algorithms to identify these spectral holes. These holes ... -
Wireless Content Centric Networks: Cross Layer Designs for Queueing, Caching, Power Control and Beamforming
Ever increasing user base of social media platforms such as Facebook, Youtube and the Over-the-Top platforms such as Netflix, Prime Video etc., has increased the demand for High Definition Videos/Contents over the Mobile ...
