1. A method comprising:
- computing, by a deterministic random number generator at a first wireless communication node, a pseudorandom number, the deterministic random number generator employing the same random number generation algorithm as a random number generator of a second wireless communication node;
determining a time of a next randomized beacon transmission using the computed pseudorandom number;
transitioning the first wireless communication node from a power saving mode to an active receiving state at a time based on the determined time; and
receiving, by the first wireless communication node over a wireless link while the first wireless communication node is at the active receiving state, a randomized beacon transmission at the determined time.

Abstract
A deterministic random number generator at a first wireless communication node computes a pseudorandom number. The deterministic random number generator employs a same random number generation algorithm as a random number generator of a second wireless communication node. The first wireless communication node determines a timing of a randomized beacon transmission using the computed pseudorandom number.
