DaCAP - A Distributed Anti-Cheating Peer to Peer Architecture for Massive Multiplayer On-line Role Playing Game

MMOG is one of the most popular amusements for people today and MMORPG is the hottest of all types of MMOGs. Due to the massive number of players, huge server load and player cheating are the two major problems of MMOGs. This paper studies the load and cheating issues of MMORPGs. Hybrid architecture by combining P2P architecture and client/server architecture is proposed for MMORPGs to reduce server load and improve scalability and flexibility. A fully distributed anti-cheating mechanism with players reciprocally monitoring is also designed in this paper. Analytical and simulation results demonstrate that the proposed architecture significantly reduces server load, increase system scalability, and efficiently detects cheating.
