Battery-conserving transmission and encoding method for wireless ad hoc networks
First Claim
1. A method for conserving power in a wireless ad hoc network, comprising:
- receiving, in a device, a burst via the wireless network, the burst including a preamble, a postamble and one or more blocks of data, the device being in one of a low power state and a powered off state at a time when the preamble is received;
determining whether the preamble of the burst includes data indicating an ID of the receiving device;
when the determining determines that the preamble includes the data indicating the ID of the receiving device, performing;
deriving, from the preamble, information indicating a time for powering on one or more components of the device to receive the one or more blocks of data included in the burst;
powering on the one or more components at a first time period based on the derived information in order to receive the data in a block of the one or more blocks;
powering off the one or more components at a specific time period from a beginning of the first time period based on the derived information;
repeating the powering on and the powering off for each of the one or more blocks of data in the burst; and
processing the received one or more blocks of data.

Abstract
A burst of data in a wireless network includes a preamble [502], a postamble [504] and one or more blocks of data [506]. A low or no power receiving device [102] receives the preamble [502]. When the preamble [502] includes an ID of the receiving device, structural information of the burst is derived from the preamble [502], indicating when at least one component of the device is to be powered on to receive the at least one block of data [506] included in the burst. The at least one component [306, 308, 310] is powered on at a first time period in order to receive the data in the one or more blocks of data. The at least one component [306, 308, 310] is powered off at a specific time period from a beginning of the first time period. The powering on and off are repeated for each of the one or more blocks of data [506] in the burst.
