摘要：Data dissemination in asymmetrical communication environment, where the downlink communication capacity is much greater than the uplink communication capacity, is best suited for mobile environment. In this architecture there will be a stationary server continuously broadcasting different data items over the air. The mobile clients continuously listen to the channel and access the data of their interest whenever it appears on the channel and download the same. The typical applications of such architecture are stock market information, weather information, traffic information etc. The important issue that is to be addressed in this type of data dissemination is – how quickly the mobile clients access the data item of their interest i.e. minimum access time so that the mobile clients save the precious battery power while they are on mobile. This paper reviews the various techniques for achieving the minimum access time. The advantages and disadvantages are discussed and explored different research areas for achieving the minimum access time.s.
