Adaptive Recursive Join Algorithm in MANET Mobile Database
Jia Jian-kun · Journal of Heilongjiang Hydraulic Engineering College · 2008
This paper is based on the characteristics of MANET mobile database system,which includes multi-hop routing,limited energy,nodes movement and disconnection frequency etc.The query plan presentation model based on multi-label tree and the cost model based on energy transmission are both raised.The adaptive recursive join algorithm is designed.The result of experiment shows that adaptive recursive join algorithm could save query energy consumption effectively and speed up enquiry response time.
