Algorithms of continuous top-k join query over structured overlay networks
Yihong Qiu · Journal of Shandong University · 2009
It is challenging to process continuous queries over structured overlay networks due to the distribution characteristic of the environment. An algorithm based on top-k join queries over structured overlay networks is presented. In the proposed algorithms,the data that can not contribute the finale top-k results was discarded based on the pre-computing results of ranked functions. The performance of the algorithms was analyzed. Our algorithms reduced the network traffic while more nodes participate in the query process.
