An Asymmetrical Wireless Communication Transceiver
BackgroundExisting solutions for short range wireless communications between a host device and a number of user devices (or sensor nodes) are characterized by the symmetrical designs of their transceiver capabilities. The digital signal processing (DSP) algorithms necessary for channel equalization, compensation and synchronization require a substantial...

An Adaptive Wireless Transmission Protocol to Maximize Allocation of the Radio Spectrum
BackgroundToday's prevalence of multimedia communication devices places a high demand on wired and wireless communication systems. The wide range of user applications and requirements, coupled with the fast variation of wireless channels, places added pressure on the already overcrowded and inefficiently allocated conventional radio spectrum. User mobility,...

An Embeddable Security Protocol to Address Vulnerabilities Inherent in Wireless Networks
Background:Wireless communication networks are now facing various risks of intrusion and attacks due to their lack of a physical association between the transmitter and legitimate receiver. The traditional methods to address these security issues are to use the higher layers of the OSI model which include conventional authentication and cryptographic...
