Enhanced IP Multimedia Subsystem (IMS) for futuristic tactical networks

A critical element of the all-IP architecture is IP multimedia subsystem (IMS). IMS is a maturing technology and has been standardized by wireless cellular industry. However, IMS was not designed and developed for using in military environments and supporting associated application services. Introducing IMS into futuristic military networks for supporting future combats has to face different challenges. In this paper, the authors explain advantages and challenges of using IMS for supporting multimedia experience in tactical environments. The paper proposes an enhancement to improve IMS performability.
