Abstract
A method and system for conserving battery strength of a mobile node, such as a laptop computer, on a wireless local area network (WLAN). The mobile node transmit symbols, which are units of data, during transmission cycles to maintain a connection with the WLAN. A battery charge level of the mobile node is measured. As the battery charge level drops below pre-defined levels, a frequency of symbol transmission for the mobile node is reduced. The reduction of the frequency of the symbol transmission results in lower power demands by a transmitter chipset of the mobile node. Thus, the mobile node is able to prolong the life of the battery of the mobile node.
Claims20
A method for transmitting data in a network, said method comprising:
- measuring a battery charge level of a mobile node on the network;
- adjusting a data transmission rate for said mobile node according to said battery charge level;
- and
- transmitting data from said mobile node at said data transmission rate.
A mobile node on a computer network having means to adjust a mobile node data transmission rate according to a battery power level of said mobile node.
A base node on a network having means to adjust a data reception rate according to a battery power level of a mobile node.
A computer program product, residing on a computer usable medium, for conserving power consumption in a wireless network, said computer program product comprising:
- program code means for determining a battery charge level of a mobile node on a network;
- program code means for adjusting a data transmission rate according to said battery charge level;
- and
- program code means for transmitting a data from said mobile node at said data transmission rate.
