PETRANET: a Power Efficient Transaction Management Technique for Real-Time Mobile Ad-hoc Network Databases

A Mobile Ad-Hoc Network (MANET) is a collection of wireless autonomous mobile nodes with no fixed infrastructure. Since no fixed infrastructure is required, MANET fits well in military operations, emergency disaster rescue, and mobile ad-hoc voting. There are many issues that have to be addressed while designing a technique for managing real-time database transactions in MANET: 1) energy limitations; 2) client and server mobility; 3) real-time constraints imposed on transactions; and 4) frequent disconnection and network partitioning. We have designed PETRANET1: a Power-Efficient Transaction management technique for Real-time mobile Ad-hoc NETwork databases that addresses the above specified issues. In this paper, we present a system prototype that we have developed to implement PETRANET for a military database application.
