In IEEE 802.15.4 wireless personal area networks (WPANs), the reliable data transmission is one of important issues such as the body information for medical treatments. Some handshaking mechanisms in literatures were studied and proposed to guarantee successful frame transmission. One of handshaking mechanisms adopts ACK frame, which is replied by the(More)
The dense wavelength division multiplexing (DWDM) technique has been developed to provide a tremendous number of wave-lengths/channels in an optical fiber. In the multi-channel networks, it has been a challenge to effectively schedule a given number of wavelengths and variable-length packets into different wavelengths in order to achieve a maximal network(More)
