Network topology always changes randomly during the communication. This paper presented a multi-ant colony based multi-path routing algorithm (MACMPR). Comparing with the conventional ant colony based route protocols, MACMPR extended the basic ant colony to multiple ones with dynamic pheromone release design. Each ant colony searches one path and repulses other ant colonies. Ants deposit pheromones...
A bilayered organic photo diode for the detection of 50-MHz signals is firstly demonstrated. With C60 as the acceptor material and pentacene as the hole transport layer, high electron/hole mobility enlarges operation bandwidth. The results enable the development of low-cost organic image sheets for the detection of high-frequency signals.
Stereo video is widely used because it can provide depth information. However, it is difficult to store and transmit stereo video due to the huge data amount. So, high efficient channel encoding algorithm and proper transmission strategy is needed to deal with the video transmission over limited bandwidth channel. In this paper, unequal error protection (UEP) based on low density parity check (LDPC)...
