Cost-Age-Time Data Organized Garbage Collection

Creator:: Lee, Dongjun
Abstract:: NAND flash based solid state drives (SSDs) require out-of-place updating due to the characteristics of flash memories. In addition, due to the mismatched granularity between read/write and erase operations, a cleaning policy involving garbage collection and wear leveling has to perform data migration incurring high overhead. Another challenge is that...

Target-based coverage extension of 802.11 MANETs via constrained UAV mobility

Creator:: Johnson, Taylor N.
Abstract:: MANETs are known to be useful in situations where mobile nodes need to communicate and coordinate in dynamic environments with no access to fixed network infrastructure. However, connectivity problems can occur when sub-groups within a MANET move out of communication range from one another. The increasingly prolific use of UAVs...

Spatial motion vector recovery in wireless high deﬁnition video transmission using H.264 over WLANs

Creator:: Gatimu, Kevin
Abstract:: Mobile devices are becoming more prevalent and complex. As a result, the wireless communication aspect of these devices is becoming increasingly signiﬁcant. At the same time, video demands in terms of availability and quality are also on the uprise. High deﬁnition (HD) video is the standard of choice for meeting...

Power reduction of MPEG video decoding for mobile multimedia systems

Creator:: Lewis, James M.
Abstract:: The purpose of this thesis is to explore methods which can reduce the power dissipation of a mobile system while decoding MPEG video. MPEG decoding is a microprocessor intensive process that makes heavy use of both the L1 and L2 caches as well as main memory. The heavy load placed...

Opportunistic bandwidth sharing through reinforcement learning

Creator:: Venkatraman, Pavithra
Abstract:: The enormous success of wireless technology has recently led to an explosive demand for, and hence a shortage of, bandwidth resources. This expected shortage problem is reported to be primarily due to the inefficient, static nature of current spectrum allocation methods. As an initial step towards solving this shortage problem,...

A statistical inference framework for finding recurring patterns in large data with applications to energy management

Creator:: You, Zeyu
Abstract:: We consider the problem of finding unknown patterns that are recurring across multiple sets. For example, finding multiple objects that are present in multiple images or a short DNA code that is repeated across multiple DNA sequences. We first consider a simple problem of finding a single unknown pattern in...

Compensation method of the excess loop delay in continuous-time delta-sigma ADCs based on model matching approach

Creator:: Guo, Jia
Abstract:: Continues-Time (CT) Delta-Sigma (ΔΣ) Analog-to-Digital Converters (ADCs) have one important constrain, namely the excess loop delay. Most previous excess lop delay compensation methods need to know the exact value of the excess loop delay in advance. However, the value of the excess loop delay is a uniformly distribution random variable....

Measurement and characterization of ultra-wideband wireless interconnects within active computing systems

Creator:: Woracheewan, Sirikarn
Abstract:: Ultra-wideband (UWB) radio has become an attractive alternative for wireless communications due to the robustness to multipath fading, low power transmission, mostly-digital implementation, and low cost. Furthermore, short-range, high data-rates applications are possible with UWB radios due to the wide spectral allocations at 3.1 - 10.6 GHz. This thesis presents...

Network coding in relay networks

Creator:: Alban, Eduardo
Abstract:: Transmission over wireless networks presents multiple technical challenges due to noise, interference, fading, power constraints and bandwidth limitation. Different solutions have been propposed to overcome these issues and some of them are treated here. Cooperative diversity has been proposed as an implementation for networks where terminals are restricted to using...
