Cooperative inter-vehicular communications in highway traffic
(2011)
In this paper, we investigate the performance of a single relay assisted cooperative vehicular network in a highway traffic scenario. Source and relaying vehicles are assumed to be traveling in the same direction with ...
Relay selection in dual-hop vehicular networks
(IEEE, 2011-02)
In this letter, we investigate cooperative diversity with relay selection over cascaded Rayleigh fading channels. In particular, we analyze the performance of a relay selection scheme for cooperative vehicular networks ...
Outage analysis of Hybrid-ARQ protocols in coherent free-space optical communications
(IEEE, 2011)
In this paper, we investigate the performance of automatic retransmission request (ARQ) protocols in coherent free-space optical (FSO) communications. Specifically, we study the outage performance of three different ...
DMT analysis of multi-hop coherent FSO communication over atmospheric channels
(IEEE, 2011)
In this paper, we investigate the diversity-multiplexing tradeoff (DMT) of a multi-hop coherent free-space optical (FSO) system over atmospheric channels. We consider a relay-assisted FSO system with decode-and-forward ...
EM-based joint time delay and channel estimation for cooperative communications
(IEEE, 2011)
In this paper, we study joint time delay and channel estimation for a cooperative communication system with amplify-and-forward (AF) relaying. The proposed joint estimator is based on Expectation-Maximization (EM) algorithm ...
On the performance analysis of multirelay cooperative diversity systems with channel estimation errors
(IEEE, 2011-06)
In this paper, we investigate the performance of an amplify-and-forward (AF) cooperative diversity system with multiple relays in the presence of channel estimation errors. We consider both conventional relaying (in which ...
Flexible architecture of relay-based wireless network for network lifetime extension with hop-count constraint
(Informa Group, 2011)
In relay-based wireless networks, messages need to be forwarded via intermediate relay mobile terminals (MTs). However, because of various transmission distances and unbalanced traffic load, some relay MTs may tend to drain ...
Preface
(Springer International Publishing, 2011-09)
Developments in the field of wireless communications continue at an unabated pace. During the previous decade starting in the early 1990s, we have seen the introduction and mass market adoption of many different types of ...
Minimum power architecture of relay-based network with bandwidth and hop-count constraints
(Trans Tech Publications, 2011)
Energy bills are on the rise and with the recent attention to saving the global environment. Saving energy (minimizing energy consumption) is becoming a standard issue for all industrial and commercial applications. Moreover, ...
