  面向无线己布匹局网绕干用优募化的拓扑把持切磋

  Secondly, the topology control for ad hoc networks with directional antennas is

  investigated, in order to maintain network connectivity while reducing node energy

  consumption and increasing network capacity.

  A distributed neighbor-based topology control approach for ad hoc networks with

  steered beam antennas, referred to as the DK-Neigh, is proposed to maintain the

  outdegree of every node equal to or slightly below a specific value K . Quadrat

  statistical methods are employed to derive analytical expressions to determine the

  critical transmission range and neighbor number K . The approach can build the

  resulting communication graph with high probability connected. Extensive

  simulations are carried out, which show that the DK-Neigh is to achieve a high

  probability (more than 96 percent) of connectivity. If width of beam is smaller than 60

  degree, average energy cost of nodes is reduced at least 15 percent than the topology

  control protocol K-Neigh using omni-directional antennas. Simulations show the

  DK-Neigh is more energy-efficient while maintaining network connectivity.

  A localized topology control algorithm for Ad hoc networks with steered beam

  directional antennas, referred to as the BATC, is proposed in this thesis. The topology

  is controlled not only by adjusting the transmission powers of nodes but also by

  changing the directional antenna’s direction. The centralized algorithm preserves the

  connectivity of the resulting topology. At the same time, the resulting network

  topology reduces energy consumption, decreases traffic interference and improves
