M-CAN: a lookup protocol for mobile peer-to-peer environment

With the development of the mobile communication technology and P2P, a combination of mobile computing and P2P, MP2P, has revealed its attractions. Compared to traditional P2P, characteristics of MP2P include unreliable connection, limited bandwidth and constrains of mobile devices. Although there have existed some classic lookup protocols for traditional P2P systems, they all fall into impropriety and inefficiency under MP2P because of their scalability limits, unreliability and requirements of bandwidth. In this paper, a new protocol, M-CAN, is proposed for implementing an efficient lookup in MP2P. By grouping and registering resources appropriately, M-CAN accelerates the lookup process in MP2P environment. Tests show that M-CAN can greatly enhance the system performance and effectivity.
