Research Approach o Investigating various MANET database system
architectures.
o Developing a real-time MANET scheduler based on deadline and mobile host disconnection to schedule real-time
transactions.
o Incorporating the energy modes of mobile hosts (Active,
Doze, and Sleep) and transaction types (Firm and Soft real-
time) into the protocols for transaction submission, processing, result delivery, caching, replication,
commit and concurrency control.
o Constructing a prototype using open source database and
network software and laptop and PDA hardware to validate
the research results.
o Using real-world applications (fire fighting, military and
virtual classrooms) for testing.

Research Objective To develop and prototype a transaction management technique for a Mobile Ad-Hoc Network (MANET) multi database management system that takes energy restriction, mobility and transaction real-time constraints into consideration.
Significant Results o Evaluated seven MANET database architectures and identified three for prototype.
o Designed the transaction submission, processing and result delivery protocols for the decentralized MANET database architecture.
o Designed a caching model (GMANET) for group-based MANET that enables many transactions to meet their deadlines.
o Designed a data replication technique that is power aware, network partition aware and real-time aware.
o Implemented the first version of the prototype (Server software: MySQL, Linux; Client software: DALP, Win CE; Location: GPS).

Broader Impact o The research results could be used for communication in collaborative environments such as military, disaster recovery and virtual meetings.
o The prototype developed will be made available for other researchers to evaluate their work in MANET databases.
