The promising projects of satellite swarm have been studied by scientists from NASA, ESA and other institutes around the world. With a massive number of pico-class, low-power and low-weight space-crafts like pico-satellites, nano-satellites, Swarm can exploring outer space environment or taking other tasks that are hard to be fulfilled by common satellites. The other merit of using swarm than common...
It is a practical challenge to provide reliable and efficient communication for data transmission in wireless sensor networks. To recover from packet losses, conventional approaches tried to use retransmission or FEC mechanisms. However, these mechanisms may introduce excessive energy overhead for reliability guarantee. By exploiting the wireless broadcast nature and the node overhearing capability,...
To solve the problem that geographic routing using traditional greedy metric decreases successful packet delivery on non-ideal communication link, we propose a link-aware geographic routing (LAG). The LAG not only expects the minimum Euclidean distance between neighbor nodes and the destination, but also requires the better link quality between the current node and relevant neighbor nodes during the...
