摘要：The idea of using mobile objects to gather samples from a sensor field has been recently proposed. Akey challenge is how to gather the sensor data in a manner that is energy efficient with respect to the sensor nodes thatserve as sources of the sensor data. An algorithmic technique called Band-based Directional Broadcast is introduced tocontrol the direction of broadcasts that originate from sensor nodes. The technique is studied by simulations thatconsider energy consumption and data deliverability. The goal is to direct each broadcast of sensor data toward themobile sink, thus reducing costly forwarding of sensor data packets. Using directional antennas to conserve bandwidthand energy consumption wireless sensor networks has attracted much attention of the research community in recentyears.Very few researches has focused on applying directional antennas to broadcasting. In this paper, we propose avirtual link reduction (VLR) based broadcasting protocol for ad hoc wireless networks using directional antennas.Simulation results show that VLR outperforms most existing omnidirectional and directional broadcasting schemes inthe sense that its normalized transmission cost and redundancy are significantly reduced. Based on the results weconclude that VLR is more bandwidth and energy –efficient.
