Simple randomized parallel algorithms for finding a maximal matching in an undirected graph
The authors present simple randomized parallel algorithms for finding a maximal matching in a unidirectional graph G=(V, E) for the CRCW and CREW models. The algorithm for the CRCW model has O(log m)Expand

Mobile Pee-to-Peer systems using Super Peers for Mobile Environments
As the number of mobile device users increases, many researches on pee-to-peer (P2P) systems in mobile environments have been carried out. In this paper, we propose two mobile P2P systems that haveExpand

A cooperative forwarding scheme for social preference-based selfishness in mobile social networks
Most schemes in mobile social networks (MSNs) assume that nodes simply forward messages without considering selfishness. We therefore first devise social preference-based selfishness for MSNs byExpand
