Abstract

Broadcast in the wireless environment has drawn much attention because it is capable of sending data to clients regardless of the number of clients. Most previous researches have aimed at obtaining an independent data item in a minimum time. However, the access probability of each data item based on query request probability has not been dealt with although a few studies have reported on allocating dependent data in different time and channels. This paper proposes a new method of allocating data items and simultaneously reducing average response time required in receiving all the dependent data items in a query. Our performance analysis shows that our proposed method gives better average response time over the existing methods.
