Multi-user diversity in a spectrum sharing system
TLDR
We investigate the effects of multi-user diversity in a spectrum sharing system where secondary users restrictively utilize a spectrum licensed to primary users only if interference perceived at primary users is regulated below a predetermined level. Expand

Enhanced Markov Chain Model and Throughput Analysis of the Slotted CSMA/CA for IEEE 802.15.4 Under Unsaturated Traffic Conditions
TLDR
In this paper, we propose an analytical Markov chain model of the slotted carrier-sense multiple-access/collision-avoidance protocol for IEEE 802.15.4 under unsaturated traffic conditions. Expand

A Street-Centric Opportunistic Routing Protocol Based on Link Correlation for Urban VANETs
TLDR
In urban vehicular ad hoc networks (VANETs), due to the high mobility and uneven distribution of vehicles, how to select an optimal relaying node in an intra-street and how to determine a street selection at the intersection are two challenging issues in designing an efficient routing protocol in complex urban environments.

Optimal modulation and coding scheme selection in cellular networks with hybrid-ARQ error control
TLDR
We propose an optimal modulation and coding scheme (MCS) selection criterion for maximizing user throughput while taking into account the number of transmissions and successful decoding probability in HARQ operation in cellular networks. Expand

An Estimated Distance-Based Routing Protocol for Mobile Ad hoc Networks
TLDR
We propose an estimated distance (EstD)-based routing protocol (EDRP) to steer a route discovery in the general direction of a destination, which can restrict the propagation range of route request (RREQ) and reduce the routing overhead. Expand

A Novel Random Access for Fixed-Location Machine-to-Machine Communications in OFDMA Based Systems
TLDR
We propose a novel random access scheme based on its fixed TA information for M2M communications at a large number of fixed-location machine devices in future orthogonal frequency division multiple access systems. Expand

Spatial Group Based Random Access for M2M Communications
TLDR
We expect that the number of machine-to-machine (M2M) devices will rapidly increase in the near future due to a growing demand for a wide range of M2M applications such as e-health, public safety, surveillance, remote maintenance and control, and smart metering. Expand
