Java-Cache hotspot data, using algorithms at least recently, java-hotspot
1. Least recently used algorithm LRU (Least recently used, Least recently used)
[Implementation]: The most common is to use a linked list to save cached data.
1. Insert new data into the head of the l
For most applications, access to hotspot data exists, that is, the Access Frequency of some data in a certain period of time is much higher than that of other data.Common hot data includes "the latest news", "the most popular news", and "movies with the largest downloads.
To understand the support of MySQL Innodb for

Samsung mobile sm-c5000 You can limit the amount of mobile data used in a mobile hotspot, and when you reach the traffic limit you set, you will automatically disable the move hotspot and disconnect all devices from the hotspot. To use this feature, follow these steps:
Note: 1. Please open the WLAN

, and the node is placed in the list header.3. When the chain is full, discard the data from the tail of the linked list and delete the corresponding data in the map.ResultsBased on the above change of the LRU algorithm, completely remove the hit cache need to traverse the chain list This drawback, performance has been greatly improved.2, using Redis cache data,
is more. I failed many times and then used the real machine test directly, through WiFi, and thanks to my colleagues for providing their own device testing. This step needs to be noted that when the Android phone opens a port when there is a blocking method we'd better put in the thread to open, after accepting the data we can not update the interface data, this is the location of Android in the more heada

Refer to association Rules algorithm, generally think of Apriori or FP, generally very few think of the hotspot, the algorithm does not know the application is less or I check the data means too low, in the Internet only found very little content, this article http:/ /wiki.pentaho.com/display/datamining/hotspot+segmentation-profiling, probably analyzed a little,
Note: 1. Please open the WLAN hotspot first.2. If you re-enable a mobile hotspot, the traffic usage resets to zero.1. In standard mode, click "Settings".2. Click "More connection Settings".3. Click on "WLAN Hotspot and network share".4. Click "Move Hotspot".5. Click "Set mobile Dat
