Electronically Reconfigurable Antenna Terminals for Energy Efficient Routing and Propagation Path Optimization Applied to Mobile Ad Hoc Networks (MANET)

摘要

In this paper, the influence of the features of the propagation channel in the performance of Mobile Ad Hoc Networks (MANET) is studied. In order to overcome the possible propagation limitations, a particular reconfigurable multiantenna terminal configuration for MANETs is provided, along with an optimization procedure to select the proper radiation pattern at each node of the network. The adequate selection of the radiation pattern at each node lets maximize the transmission/reception capabilities of the wireless network, depending on the propagation channel features and their evolution in time. In addition, a modified routing strategy is proposed, based on the existence of an alternative route at each node, provided that the main one is not available because of propagation issues or incidences in the network.
