Multi-agent Prognostic Health and Usage Monitoring (MULTI-PHUM)
 

Multi-agent Prognostic Health and Usage Monitoring (MULTI-PHUM) is our prototype software that was developed as a result of a NASA Phase II SBIR in May 2007 (Patent pending, MULTI-PHUM was copyrighted in 2008.).  It performs fault diagnosis and prognosis with a friendly user interface. The Multi-PHUM is used to monitor the health of a dynamic system, providing repairing action and explanation when the system is running abnormally. It also estimates remaining useful lifetime or time-to-failure of the abnormal part to schedule maintenance operations without affecting adversely the overall system functionalities so that uptime is maximized. The diagnosed impending failures, the remaining useful lifetime of the process and the scheduled maintenance operations lead to Condition Based Maintenance (CBM).

Wireless Communications
 

IIS Corp has a patent on Power Control in Wireless Communications
Our  Actor Critic Fuzzy Reinforcement Learning (ACFRL) algorithm optimizes the battery Power use in crowded networks by Controlling the transmitter power in wireless communication networks and provides multiple benefits. It allows interfering links sharing the same radio channel to achieve required quality of service (QoS) levels, minimizing the power spent in the process and extending the battery life of mobile users. Moreover, by judiciously using power to achieve their QoS goals, interference is mitigated and the network capacity increases. 

The main dilemma that the transmitter (agent) faces in controlling its power is the following. When the agent observes high interference in the channel, it recognizes that it will have to spend a lot of power to overcome the interference and transmit a packet successfully. Therefore, a better strategy is to back off, buffer the traffic and wait for the interference to subside. However, as the agent is backing off, the buffer is filling up with newly arrived  packets, which increases buffering delays and pushes the agent to become more power-aggressive to reduce its backlog. The interference in the channel is proportional to the power used by the agents using this channel. Therefore, a power-aggressive agent may cause other agents to go into a backoff mode or also become aggressive. 
In our research, we develop and analyze new strategies for coordinated power control among multiple agents. The agents can potentially be heterogeneous by using different initial policies.

System of Systems (SOS)
 

Another area of important research is the field of System of Systems (SOS).in which IIS Corp has access to a powerful team including the pioneers of the field.

 
DEVS
 
DEVS is a formalism, which provides a means of specifying the components of a system in a discrete event simulation. In DEVS formalism, one must specify Basic Models and how these models are connected together. These basic models are called Atomic models and larger models which are obtained by connecting these atomic blocks in meaningful fashion are called Coupled models. A Java-based implementation of DEVS formalism, DEVSJAVA, can be used to implement these atomic or coupled models.
