Optimal Non-Coherent Detector for Ambient Backscatter Communication System
Sudarshan Guruacharya, Xiao Lu, Ekram Hossain
The probability density function (pdf) of the received signal of an ambient backscatter communication system is derived, assuming that on-off keying (OOK) is performed at the tag,…
Edge Caching for Cache Intensity under Probabilistic Delay Constraint
Tachporn Sanguanpuak, Sudarshan Guruacharya, Nandana Rajatheva +1
In order to reduce the latency of data delivery, one of techniques is to cache the popular contents at the base stations (BSs) i.e. edge caching. However, the technique of caching…
Inter-Operator Infrastructure Sharing: Trade-offs and Market
Tachporn Sanguanpuak, Sudarshan Guruacharya, Ekram Hossain +1
We model the problem of infrastructure sharing among mobile network operators (MNOs) as a multiple-seller single-buyer market where the MNOs are able to share their own base statio…
On Spectrum Sharing Among Micro-Operators in 5G
Tachporn Sanguanpuak, Sudarshan Guruacharya, Ekram Hossain +2
The growing demand in indoor small cell networks has given rise to the concept of micro-operators (MOs) for local service delivery. We model and analyze a spectrum sharing system i…
Resource Allocation for Co-Primary Spectrum Sharing in MIMO Networks
Tachporn Sanguanpuak, Sudarshan Guruacharya, Nandana Rajatheva +1
We study co-primary spectrum sharing concept in two small cell multiuser network. Downlink transmission is explored with Rayleigh fading in interfering broadcast channel. Both base…
Multi-operator spectrum sharing using matching game in small cells network
Tachporn Sanguanpuak, Nandana Rajatheva, Mehdi Bennis +2
In this paper, we study a problem where multiple operators (OPs) need to share a common pool of spectrum with each other. Our objective is to maximize the social welfare, defined a…
Approximation of Meta Distribution and Its Moments for Poisson Cellular Networks
Sudarshan Guruacharya, Ekram Hossain
The notion of meta distribution as the distribution of the conditional coverage probability (CCP) was introduced in \cite{Haenggi2015}. In this letter, we show how we can reconstru…
Edge Caching in Delay-Constrained Virtualized Cellular Networks: Analysis and Market
Tachporn Sanguanpuak, Sudarshan Guruacharya, Ekram Hossain +3
Caching of popular contents at cellular base stations, i.e., edge caching, in order to eliminate duplicate transmission through the backhaul can reduce the latency of data delivery…
Infrastructure Sharing for Mobile Network Operators: Analysis of Trade-offs and Market
Tachporn Sanguanpuak, Sudarshan Guruacharya, Ekram Hossain +2
The conflicting problems of growing mobile service demand and underutilization of dedicated spectrum has given rise to a paradigm where mobile network operators (MNOs) share their…
Level-Triggered Harvest-then-Consume Protocol with Two Bits or Less Energy State Information
Sudarshan Guruacharya, Vandana Mittal, Ekram Hossain
We propose a variation of harvest-then-consume protocol with low complexity where the harvest and consume phases change when the battery energy level reaches certain thresholds. Th…
Battery Recharge Time of a Stochastic Linear and Non-Linear Energy Harvesting System
Sudarshan Guruacharya, Vandana Mittal, Ekram Hossain
Systems harvesting energy from a stochastic source have been widely studied in the literature. However, we are not aware of any work that deals with the time it takes for a battery…
Self-Sustainability of Energy Harvesting Systems: Concept, Analysis, and Design
Sudarshan Guruacharya, Ekram Hossain
Ambient energy harvesting is touted as a low cost solution to prolong the life of low-powered devices, reduce the carbon footprint, and make the system self-sustainable. Most resea…
SINR Outage Evaluation in Cellular Networks: Saddle Point Approximation (SPA) Using Normal Inverse Gaussian (NIG) Distribution
Sudarshan Guruacharya, Hina Tabassum, Ekram Hossain
Signal-to-noise-plus-interference ratio (SINR) outage probability is among one of the key performance metrics of a wireless cellular network. In this paper, we propose a semi-analy…
