Wireless sensor networks are posed as the new communication paradigm where the use of small, low-complexity, and low-power devices is preferred over costly centralized systems.There are times when just monitoring systems is enough, but for large enterprise applications that demand maximum efficiency and effectiveness, you should consider tracking complete transactions. Monitoring is the process of continually collecting data points on each system. ... Tracking a transaction is the process of looking at the data that is input into a process and the results that are issued, and it will include the timing detail about how long it took as well as what happened inside the process.
