摘要：Neighbor discovery is a component of communication and access protocols for ad hoc
networks. Wireless sensor networks often must operate under a more severe low-power
regimen than do traditional ad hoc networks, notably by turning off radio for extended
periods. Turning off a radio is problematic for neighbor discovery, and a balance is needed
between adequate open communication for discovery and silence to conserve power. This
paper surveys recent progress on the problems of neighbor discovery for wireless sensor
networks. The basic ideas behind these protocols are explained, which include deterministic
schedules of waking and sleeping, randomized schedules, and combinatorial methods
to ensure discovery.
