[0094] As for the third example, the following step-by-step instructions for Figure 10 The degraded search technique for the vertex / edge graph G1 shown. According to step 1 of Table 1, let the modified vertex / edge G=G1, and set the edge number variable to 0 (j=0).

[0095] In step 2 of Table 1, in the modified vertex / edge graph G, an edge is selected as edge e in the modified vertex / edge graph G 0 , so the associated vertices of the two edges have the minimum rank. In particular, in the modified vertex / edge graph G: vertex C, vertex E, and vertex G have rank 1, respectively. Furthermore, the only neighbor vertex of vertex C is vertex F with rank 2. The only neighbor vertex of vertex G is vertex F with rank 2. Therefore, we arbitrarily choose edge e 0 =BC.

[0096] for edge e 0 , e 1 ,... e j The current set of , in the modified vertex / edge graph G=G1-{e 0 , e 1 ,... e j}, if edge e j Adjacent sides of = , increment the edge number variable (increment j) to move...

Abstract

The present invention discloses a power management technique for a network including a plurality of computing devices. Power management techniques include identifying an order in which one or more of a plurality of computing devices may transmit data within specified time intervals. In one aspect, the number of wakeups for computing devices within a network is reduced by adding a number of adjacent channel time allocation periods within a defined time interval for sharing computing devices. In one aspect, the network may be based on time division multiple access (TDMA).

Description

technical field [0001] The present invention relates to a computing device, and more particularly to conserving power in a network including the computing device. Background technique [0002] Certain time division multiple access (TDMA) networks connect multiple computing devices via links based on TDMA technology. TDMA is used to subdivide network access among multiple computers within multiple consecutive time slots. During each time slot of the time frame, one computing device is assigned to use the network. If the computing device is sending and receiving data during that particular time slot, the computing device may wake up during that particular time slot. In order to conserve power (particularly in wireless networks and / or utilizing batteries for operations such as Personal Display Assistants (PDAs) and handheld or cellular telephones), it is desirable to put the computing device to sleep during these time slots when data is not being sent or received . However,...
