Problems solved by technology

This approach results in almost instant discovery of new wireless devices, but at the cost of increased power consumption and overall efficiency
Even worse, the architecture places limits or rules on when or how many queries / responses can be dispatched, with the result that network congestion can develop very quickly
This problem is exacerbated in particularly crowded areas, such as sports / entertainment venues and urban environments, where a device looking for a new connection may elicit a response from any other wireless device within range resulting in literally thousands of replies

Embodiment Construction

[0023] The disclosure is described in detail with reference to the following drawings and description. The components in the figures are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the invention. Additionally, in the figures, like reference numerals indicate like corresponding parts or devices throughout the different views.

[0024] In this disclosure, a network is established when as few as 2 peer stations have established connections with each other. In this context, one station will already be a station that "supports" a given service or application, while another station will already be "in search" of this service or application. Since multiple stations may be searching for a common service, such as an Internet gateway, there are frequently situations where many stations attempt to connect with a unique service support station. In this case, it sometimes makes more sense to consider the service support station as "connecte...

Abstract

A method for synchronizing discovery of wireless services or applications in a wireless network using a recurring time interval T, wherein wireless devices within the wireless network can be in one of a plurality of predetermined time states. The method includes selecting a time state from among a plurality of time states, performing a discovery during a recurring time interval T of a first wireless device supporting a given service or application in the selected time state, and during the recurring time interval T The above steps are repeated in the corresponding cycle time interval T until all the multiple predetermined time states have been selected.

Description

[0001] Cross References to Applications [0002] This application claims the benefit of US Provisional Application No. 61 / 592,121, filed January 30, 2012, the disclosure of which is hereby incorporated by reference in its entirety. technical field Background technique [0003] The background description provided here is for the purpose of generally presenting the context of the disclosure. To the extent the work is described in this Background section, the work of the presently named inventors and aspects of the description that would not otherwise be qualified as prior art at the time of filing are neither expressly nor implicitly admitted as relative to prior art for this disclosure. [0004] Wireless discovery is the process by which Wi-Fi enabled mobile devices such as cellular phones, laptops, tablets, etc. (collectively referred to as "stations") locate and eventually each other and connect to a wireless network and eventually connect to each other. Typically, this...
