Optimized consistence maintenance strategy in semantic caching

Semantic caching is an attractive method when disconnection or connection jam happens in a distributed computing or a mobile computing environment. However, in semantic caching, the consistency maintenance technology is a challengeable technology. The existent methods have many limitations that restrict the practicability of semantic caching in a great extent. This paper extends the existing work in three ways: firstly, corrects relative concepts in previous works and gives a kind of valid consistency maintenance strategy; furthermore, produces related optimization functions to simplify the updating queue; finally, implements the simulation system to test the performance of our works in semantic caching.
