Abstract EN
Searching and retrieving the demanded correct information is one important problem in networks; especially, designing an efficient search algorithm is a key challenge in unstructured peer-to-peer (P2P) networks.
Breadth-first search (BFS) and depth-first search (DFS) are the current two typical search methods.
BFS-based algorithms show the perfect performance in the aspect of search success rate of network resources, while bringing the huge search messages.
On the contrary, DFS-based algorithms reduce the search message quantity and also cause the dropping of search success ratio.
To address the problem that only one of performances is excellent, we propose two memory function degree search algorithms: memory function maximum degree algorithm (MD) and memory function preference degree algorithm (PD).
We study their performance including the search success rate and the search message quantity in different networks, which are scale-free networks, random graph networks, and small-world networks.
Simulations show that the two performances are both excellent at the same time, and the performances are improved at least 10 times.
