Modelling concurrent mobile transactions execution in broadcasting environments

الملخص EN

Broadcast is an efficient and scalable method for resolving the bandwidth limitation in a wireless environment.

There is a trade-off between clients’ access time and throughput for update mobile transactions in on-demand data dissemination environments.

Data scheduling at the fixed server can allow more transactions to commit while retaining the access time for each transaction.

In this paper, we present a data scheduling scheme for both read only and update mobile transactions in pull-based broadcasting environments.

Rather than consider access time, which is well studied elsewhere in [1, 2, 3] , our concern is to examine the probability that a mobile transaction is able to avoid conflict and commit.

Specifically, a set of formulas giving an analysis of this probability is examined.

Furthermore, a report of a simulation study for validating these formulas is also provided.
