In this paper, we study the performance and impact of maintaining temporal consistency on a recently proposed concurrency control protocol for processing transactions in broadcast environments. This protocol offers autonomy between mobile clients and the server such that mobile clients can read consistent data off the air without contacting the server. However, most of the existing mobile computing applications, such as information dispersal systems for stock prices and weather information, are comprised of real-time read only transactions. In order to deliver timely and useful results, real-time transactions must read temporal consistent data in addition to completing the execution before their deadlines. A number of approaches to maintaining temporal consistency are studied through a series of simulation experiments. Results show that taking advantage of data semantics and temporal consistency requirement can improve the performance of mobile read only transactions in broadcast environments.
