Power management of high-bandwidth wireless mesh network

Abstract

There is provided a power management method to extend the battery life of wireless routers being parts of Wi-Fi or other high-bandwidth wireless mesh networks. The method comprises the steps of connecting the clients, such as smart phones or computers, on a constant, low- bandwidth connection, using the low-bandwidth protocol / network of the routers, and to activate the high-bandwidth protocol of the router, thus providing a high-bandwidth connection to clients, only when either a request is sent by the client, or the file to transfer has a size to important to be supported by the low-bandwidth connection. There is also provided a method to minimize the power consumption of a mesh of wireless routers by activating the high-bandwidth protocol to only the routers that are located on the shortest route between the main router and the client.

Description

[0001] This patent application claims the benefit of priority to US Patent Application Serial No. 62 / 059,286, entitled "Power Management for High Bandwidth Wireless Mesh Networks," and filed October 3, 2014 in the US Patent and Trademark Office. technical field [0002] The present invention relates generally to the field of wireless telecommunications networks. More specifically, the present invention relates to power management for battery powered or autonomous high bandwidth wireless mesh networks. Background technique [0003] Like Dust networks, ZigBee or DASH7, wireless mesh network technologies (hereinafter referred to as "WS networks") are typically optimized for the topology of static multi-hop wireless sensor networks. Their bandwidth is usually limited to speeds of kilobauds per second (kbps). Since a typical wireless router may last for years on D-size batteries or similar, such a network draws very little power. Accordingly, such wireless mesh networks are des...

Problems solved by technology

[0007] For example, despite performing basic low-bandwidth networking functions 10 times per second, devices based on this type of ultra-low power integrated circuit can have a duty cycle of less than 1% and have a time-averaged power consumption of 10uW

[0008] 1- Sleep for 97ms, consume 3uW;

[0009] 2- Wake up within 1ms, consume 1000uW;

[0015] 2- Wake up within about 3000ms and consume about 50000uW;

[0016] 3- Execute the networking function within about 1ms and consume about 500000uW;
