In this paper we analyze the capacity improvement by directional antennas over omni-antennas in wireless sensor networks. The capacity in our analysis is the end-to-end per-node throughput. We analyze the typical traffic pattern for sensor networks, where traffics are destined to or originated from the sink. The main results of our analysis are summarized as follows: 1) The network capacity is O(1/N ) for both omni and directional antennas, where N is number of sensor nodes in the network. 2)doi:10.1145/2379799.2379802 fatcat:gvukowwi35ep7fvnpnt6sc2ms4
