Efficient Data Consistency Schemes in 2-Tier Cellular Networks

Mobile computing raises many research issues due to the different characteristics of computing resources. In this paper, we present the concept of 2-tier data consistency schemes in which the messages to be transferred are handled by the appropriate MSS(Mobile Support Station). Instead of just relaying messages among MH’s (Mobile hosts), MSS’s maintain data and handle the messages together on behalf of the mobile hosts in its area. Also, different data consistency schemes can be applied for each different level (wireless or wired communication level) to reduced communication overhead.
