Managing real-time database transactions in mobile ad-hoc networks

In a mobile ad-hoc network (MANET), mobile hosts can move freely and communicate with each other directly through a wireless medium without the existence of a fixed wired infrastructure. MANET is typically used in battlefields and disaster recovery situations where it is not feasible to have a fixed network. Techniques that manage database transactions in MANET need to address additional issues such as host mobility, energy limitation and real-time constraints. This 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. This paper then reports the simulation experiments that were conducted to evaluate the performance of the proposed solution in terms of number of transactions missing deadlines, total energy consumption and the distribution of energy consumption among mobile hosts.
