IMS

IMS

IMS stands for information management system, which is a set of business processes, technology tools, and policy guidelines used to manage the life cycle of information and knowledge. It was first developed by IBM in 1958 for NORAD and released in 1963 as the first ever DBMS. The IMS scheme is used in applications where better error performance is more important than high data rate.From: Optimizing Project Management [2020], Cloud Computing Strategies [2019], Effect of Pointing Error on the Performance of Improved Modified Switching Scheme of Hybrid FSO/RF System under Mixture Gamma Atmospheric Turbulence [2022]

It is important to note that the IMS is access-independent. Hence it can support IP-to-IP sessions over packet data GPRS/EDGE or 3G, packet data CDMA, IP wireless LANS 802.11 and 802.15, as well as wire-line IP networks. The IMS consists of session control, connection control, and application services framework. Security interfaces were also introduced in Release 5, which included the access security, access domain security, and lawful interception interface.

In case of identical average data rate, the IMS scheme gives a reduced amount of outage probability in comparison to the HS scheme. In this case, the proposed scheme provides same data rate and BER but high reliability. Thus, the proposal of designing a new switching scheme (IMS scheme) achieves the primary objective of high link reliability of hybrid systems. In case of identical outage probability, the IMS scheme provides same outage probability, less BER but less data rate also. So in this scenario, the choice between IMS and HS shall be governed by the requirements of data rate/ BER. The IMS scheme may be used in such applications where better error performance is the key requirement rather than high data rate. Thus, for both cases it is seen that IMS scheme exhibits better performance in terms of both outage probability and BER as compared to HS scheme.
