Effect of directional antennas on spatiotemporal sampling in clustered sensor networks
2006
IEEE Wireless Communications and Networking Conference, 2006. WCNC 2006.
Preserved Fulltext
We also propose a simple analytical approach to optimizing the antennas beam width in order to improve the spatiotemporal sampling rate by maximizing the transport capacity of the network. ...
In this paper, we investigate this tradeoff between spatial reuse and connectivity in the context of the spatiotemporal sampling rate that can be achieved by the cluster. ...
In this paper, we investigate the effects of directional antennas on spatiotemporal sampling process in clustered sensor networks. ...
