Common Notion of Time in the MIDAS MANET: Arrogant Clocks

چکیده

The EU-IST-MIDAS project has developed middleware that helps to simplify development of software for mobile ad-hoc networks (MANET) with distributed data. One of the challenges in distributed systems is the time difference in the various nodes that are part of the MANET. Time differences can disrupt the consistency of the data stored in a distributed database upon replication. This paper argues why clock synchronisation does not solve the needs of the MIDAS MANET, and introduces the concept of arrogant clocks as a method for maintaining a common notion of time in order to improve consistency when replicating database records between the different nodes in the MANET.

Estimating Reliability in Mobile ad-hoc Networks Based on Monte Carlo Simulation (TECHNICAL NOTE)

Each system has its own definition of reliability. Reliability in mobile ad-hoc networks (MANET) could be interpreted as, the probability of reaching a message from a source node to destination, successfully. The variability and volatility of the MANET configuration makes typical reliability methods (e.g. reliability block diagram) inappropriate. It is because, no single structure or configurat...
