Impact of location heterogeneity on random walk mobility models
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Conference Paper)
This paper investigates random walk mobility models with location heterogeneity, where different locations may have different neighboring regions.With the assumption of totally n locations, we consider two cases, i.e., ...
Improving macrocell downlink throughput in rayleigh fading channel environment through femtocell user cooperation
(2013 , Article)
This paper studies cooperative techniques that rely on femtocell user diversity to improve the downlink communication quality of macrocell users. We analytically derive and evaluate the achievable performance of these ...
Securing vehicle-to-grid communications in the smart grid
(2013 , Article)
Using vehicle-to-grid (V2G) services, battery vehicles (BVs) may help the smart grid alleviate peaks in power consumption. However, wireless communications infrastructure between BVs and the smart grid also introduce severe ...
Impact of channel estimation error on bidirectional MABC-AF relaying with asymmetric traffic requirements
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Article)
Channel estimation error results in severe performance deterioration in wireless networks. In this paper, we study the impact of imperfect channel estimation (ICE) on the outage performance of bidirectional relaying where ...
Carrier aggregation for LTE-advanced: Uplink multiple access and transmission enhancement features
(2013 , Article)
Multiple access and transmission enhancement in support of carrier aggregation techniques has been actively studied in the 3GPP LTEAdvanced standardization process of the nextgeneration mobile broadband communication ...
A measurement study on the topologies of BitTorrent networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Article)
BitTorrent (BT) is a widely-used peer-to-peer (P2P) application. Most of BT's characteristics (except the topology) have been studied extensively by measurement approaches. In this paper, we deploy a measurement system to ...
Copy limited flooding over opportunistic networks
(2013 , Conference Paper)
Mobile devices with local wireless interfaces can be organized into opportunistic networks which exploit communication opportunities arising from the movement of their users. With the proliferation and increasing capabilities ...
A survey on communication infrastructure for micro-grids
(2013 , Conference Paper)
A micro-grid is a small scale power supply network that is designed to provide electricity to a small community with its own renewable energy sources. Due to distributed generation variability, security and load sharing ...
Social interaction increases capacity of wireless networks
(2013 , Conference Paper)
A network model with both social and communication characteristics is considered. Different capacity regions are computed as a function of the social network size for each node. It has been shown that as the social ...
Capacity and delay analysis for data gathering with compressive sensing in wireless sensor networks
(2013 , Article)
Compressive sensing (CS) provides a new paradigm for efficient data gathering in wireless sensor networks (WSNs). In this paper, with the assumption that sensor data is sparse we apply the theory of CS to data gathering ...
