Paper Abstract:
|
Bandwidth variability and handoff of wireless communication may cause mobile transaction operations to be delayed. A
shared data item that is locked by a mobile transaction could obstruct operations of other fixed host transaction from
being executed. So the response time for fixed host transaction execution is lengthened because of the delayed
transmission for mobile transaction operations .In this paper, we extend the two phase locking protocol for mobile
databases to deal with this challenge. The objective of this adaptation is higher throughput for fixed host transaction in
present of mobile transaction. Simulation studies of our protocol show a better performance than if we used standard two
phase locking protocol. |
