In this paper, we propose an algorithm to support distributed mobile sensors to collect data in sensing areas needing to be observed. The algorithm exploits random positions of mobile sensors to measure the area and applies compressive sensing (CS) to reconstruct all sensed data based on a certain number of CS measurements. At a time instant, the sensors add all readings within their sensing range...
Mobile sinks have been shown to balance energy and help to achieve uniform power consumption across wireless sensor networks (WSN). In this paper, a compressive sensing (CS) based algorithm for distributed mobile sensors to collect data from static sensors deployed in a sensing area is proposed. The mobile sensors deployed randomly in the field are capable as mobile sinks. They move randomly in the...
In this paper, we propose an algorithm supporting distributed mobile sensor networks (MSN) for scalar field mapping that has many applications such as environmental monitoring or battle field surveillance, etc. We exploit the integration between compressive sensing (CS) and the collaboration of the mobile sensors. In the algorithm each distributed mobile sensor measures at random positions in the...
The demand of next generation mobile communications includes not only high data transmission rate, indoor coverage but also the capability to provide QoS guaranteed services to high user density areas under the constraint of limited radio spectrum. In order to fulfill these requirements effectively, cognitive radio and femtocell are considered as promising technologies. Moreover, the dearth of simulation...
Merging IP routing and mobile communication poses many challenges especially for a dynamic, heterogeneous networking environment such as a Naval Task Force. In this paper, we present an effort to design, develop, test and demonstrate an interoperable coalition interface for a Naval Task Force for the four-nation Coalition Networks for Secure Information Sharing (CoNSIS) project. A field experimentation...
The objective of this thesis is to determine the value of software developers for the mobile value chain. To identify different strategies for mobile platforms integrating developers, two case studies are conducted: Apple and Google. Porter's approach of key activities is used to identify, how the two companies create a sustainable competitive advantage and which roles developers fulfill within the...
In this paper, we present exact analytical expressions for the outage probability of cooperative diversity wireless relay networks operating in various decode-and-forward (DF) protocols (fixed, adaptive, and incremental relaying) under Rayleigh fading conditions. Current works only analyze the asymptotic behavior of these protocols, either under high signal-to-noise ratios (SNR) or under low SNR-low...
In mobile communications, time varying channels make the available channel information out of date. Timely updating the channel state is an obvious solution to improve the system performance in a time varying channel. However, a better knowledge of the channel comes at the cost of a decrease in the system throughput. Thus, predicting the future channel conditions can improve not only the performance...
