LTE Physical Layer Performance Analysis

May 15, 2014
Author(s)
Wen-Bin Yang, Michael R. Souryal
In this report, we present results of a physical layer performance study for all MCSs (from MCS0 to MCS28) in terms of block error rate (BLER) and spectral efficiency. The results are obtained by using the Steepest Ascent LTE toolbox for MATLAB which

Efficient Field Coverage in Mobile Sensor Networks: A CPS Perspective

April 17, 2014
Author(s)
Kamran Sayrafian, Hamid Mahboubi, Amir G. Aghdam
Mobile sensor networks (MSN) are an excellent example of Cyber-Physical Systems where motion capability of the network nodes offers an opportunity to co-design the physical and cyber components of the system. As sensor nodes have limited energy resources

Power Supply Issues for Wireless Sensor Networks: A Review

March 1, 2014
Author(s)
Wenqi Guo, William M. Healy, Mengchu Zhou
Wireless sensor networks (WSNs) have enabled numerous embedded wireless applications in different areas such as military/battlefield, environmental monitoring, and intelligent building systems. They consist of a large number of nodes that need to operate

Dynamic Spectrum Access: Current State of the Art and Future Challenges

February 2, 2014
Author(s)
Anirudha Sahoo, Michael R. Souryal
Dynamic Spectrum Access (DSA) is emerging as a promising technology to mitigate the spectrum scarcity caused by static frequency allocations. Despite the clear need for more efficient allocation, however, DSA faces a number of challenges, chief among them

Analysis for Dynamic Metrology

January 30, 2014
Author(s)
Andrew M. Dienstfrey, Paul D. Hale
Diverse measurement contexts require estimates of time varying quantities. Ideally the measurement device responds to signal variations significantly more rapidly than the modulation of the signal itself. If so, then well-developed techniques may be used

Greedy Backpressure Routing for Smart Grid Sensor Networks

January 13, 2014
Author(s)
Hamid Gharavi
In this paper, a greedy backpressure routing protocol is proposed for multigate mesh networks. This protocol evaluates the greedy backpressure metric (GBM) value of mesh points and routes packets in the direction of the steepest gradient. The GBM value is
