Push technology is a kind of technology that automates the information delivery process without requiring users to request the information that they need. Wireless has experienced explosive growth in recent years; “push” will be the predominant wireless service delivery paradigm of the future. We can expect a large number and a wide variety of services, alerts and messages, such as promotional content, to be delivered to consumer’s phones or PDAs. To push information to wireless device becomes a challenge because of the problem of intermittent communication links and resource constraint on wireless devices as well as limited bandwidth. This chapter describes an efficient multicasting mechanism that “pushes” pre-specified information to groups of wireless devices. The mechanism is able to operate with limited bandwidth and also overcome the connectivity problem. A framework has been designed that implements the concept of push technology to multicast the sales information via wireless technology. The design of a message-oriented system for wireless information is described and that is followed by the implementation details that are compliance to Java Messege Service (JMS).
