A power-aware technique to manage real-time database transactions in mobile ad-hoc networks

A mobile ad-hoc network (AMNET) is a collection of wireless autonomous mobile hosts which are free to move randomly, thus forming a temporary network without any fixed backbone infrastructure. AMNET is typically used in battlefields and disaster recovery situations where temporary network connectivity is required Techniques that manage database transactions in AMNET need to address additional issues such as host mobility, energy limitation and real-time constraints. The paper proposes a solution for transaction management that reduces the number of transactions missing deadlines while balancing the energy consumption by the mobile hosts in the system. The paper then presents a performance study by means of simulation
