Space-time efficient network coding for wireless multi-hop networks
Network coding has been recently proposed as a new promising technique that can potentially improve the performance of a wireless multi-hop network significantly. However, most existing studies in this field perform network coding without considering the interplay between transmission power/rate and network coding gain. In many scenarios, the selection of the transmission power/rate brings big ...
متن کاملOn the Design and Tradeoff of Wireless Downlink Space Time Scheduler on Network Capacity and Coverage
It is well-known that wireless scheduling algorithm could exploit multi-user diversity to enhance the network capacity of wireless systems. However, the advantage of scheduling with respect to network coverage is a relatively unexplored topic. We consider a wireless system with an access point or base station equipped with transmit antennas as well as mobiles with single receive antenna. With m...
متن کاملCommunity surveys through space and time: testing the space-time interaction in the absence of replication.
In order to test hypotheses about changes in the environment induced by man, including climatic change, ecologists are sampling portions of the environment repeatedly across time. This paper describes a method for testing a space-time interaction in repeated ecological survey data, when there is no replication at the level of individual sampling units (sites). This methodological development is...
