Slack time scheduling for managing database transactions in mobile ad-hoc networks

Abstract

In a mobile ad-hoc network (MANET), traditional mobile nodes (TMNs) are movable and can communicate with other TMNs through a wireless medium without any infrastructure network. MANET is focused in the field of applications such as military, disaster recovery situations where it is difficult to establish a fixed network. The network systems that schedule database transactions in MANET need to focus additional issues such as energy limitation and scheduling constraints. This paper proposes a solution for scheduling database transactions that reduces the number of transaction missing deadlines while balancing the energy consumption by the TMNs in the system. The proposed solution is setting up reasonable concurrency control when guaranteeing isolation. This paper then reports the simulation experiments that were conducted to evaluate the effectiveness of the proposed system in terms of number of transaction missing deadlines, total energy consumption and distribution of energy consumption among TMNs.
