A new collaborative interaction of mobile phones

Aim To solve the sharing conflict problem of a multi-user graphical Interaction tool over mobile phones,improve the response speed of system and save the communication cost.Methods Because of the low bandwidth of mobile phone,a new concurrency control algorithm for multi-user shared whiteboard is proposed.Results It is proved by probability analyzing that MBC algorithm can reduce the conflict probability and greatly improve the response speed of system and save the communication cost.Conclusion An example is presented to demonstrate the feasibility and validity of the algorithm.
