The design of effective routing protocols in airborne networks (ANs) relies on suitable mobility models that capture the movement patterns of airborne vehicles. Expand

We present a comprehensive survey and comparative analysis of mobility models that are either adapted to or developed for AN evaluation purposes. Expand

The audio/visual mapping problem of speech-driven facial animation has intrigued researchers for years. Expand

A new network layer that can support multihop communications efficiently in WiMAX networks and that can fully exploit the features of the WiMAX standards. Expand

We introduce a systematic approach to determine what to teach and how to teach in an ethics curriculum using the Delphi technique, a process-driven research method; and an instructional design model. Expand

This paper presents a closed form designs of complex orthogonal space-time block codes of rates (k + I)/(2k) for 2k-1 or 2k transmit antennas. Expand

We present an Error Correction Based Cipher (ECBC) that combines error correction and data security as one unit so that both encryption and encoding could be carried out at the physical layer. Expand

In this paper, we investigate the symbol-error-rate (SER) for binary phase-shift keying (BPSK) and QPSK modulations, but the approaches can be generalized to other constellation schemes. Expand

In this paper, we explore the advantages of network coding and space–time coding in improving the performance of two-way-relayed communications where two terminals absent of direct links exchange information through a single relay in between. Expand
