An Improved Distributed Resource Discovery Algorithm
一种改进的分布式资源发现算法

The Flooding algorithm is a traditional resource discovery algorithm in disrtributed networks. However.it is shown that the Flooding algorithm do not perform well in ad-hoc mobile networks. In this paper, we present an algorithm called Double-direction-feedback (DDF) based on the Flooding algorithm, which uses mobile agent to transmit the resource messages between the network nodes. We prove that DDF can achieve better results in the performance by good convergence and is adaptive to the ad-hoc mobile network envirement.
