Performance optimality enhancement algorithm in DDBS (POEA)

作者：

Highlights：

• A new dynamic data allocation algorithm for non-replicated DDBS (POEA) is presented.

• POEA improves fragments reallocation to different sites.

• POEA adopts the shortest path between the old location and the new anticipated location.

• Experimental results show that POEA has efficiently reduced the transmission cost.

• Minimizes frequency and time spent on fragment migration over the network sites.
