Background/RobotSim

Goal Develop communication capability in Cooperative Robotics Simulator in order to provide a basic communication between simulated robots.

Primary Use cases

Use case 1 – Send Message

Use case 2 – Set parameters

Requirements Send Broadcast message  Support the ability to send broadcast message.  Support the ability to receive broadcast message.  Only simulated robot that has broadcast capability shall send or receive broadcast message.  Support the ability to delay message before sending out.  Simulated robots with active send link shall send broadcast message to other robots.  Only simulated robot with active receive link shall receive broadcast communication.

Requirement (cont.) Send Point-to-Point message  Support the ability to send point-to-point message.  Support the ability to receive point-to-point message  Only simulated robot that has point-to-point capability shall send or receive point-to-point message.  Shall delivery to only one simulated robot specified by a destination address.  Shall support the ability to delay message before sending out.  Simulated robots with active send link shall send point-to-point message to only robot with active receive link  Only simulated robot with active receive link shall receive point-to- point message.  Simulated robots with range restriction shall send messages within range limit

Requirement (cont.) Set Parameters  Support the ability to set delay time for each robot or the entire system.  Support the ability to start up or shutdown all the communication links or for each robot. It shall support the ability to activate/deactivate send link only, receive link only or both of them.  Support the ability to set range limit for each simulated robot.  Support the ability to set message delivery probabilities.

Cost Estimation Function Point Analysis ParametersSimpleAvgComplexTotal InputSign on request Request to send messages. Request to start up/ shutdown links Set parameters OutputSuccess or failure to sign on Success or failure to send messages. Success or failure to start up / shutdown links. Success or failure to set parameters. Distribute messages to all recipients Total 33

Cost Estimation (cont.) FP = Unadjusted Function Points * ( *  F i ) (where Fi are complexity adjustment factors) Complexity Adjustment FactorsValue Are data communications required5 Is the code designed to be reusable3 Total Complexity Adjustment Factors8 Therefore, total Adjusted Function Points is 33 * 0.73 = Number of Lines of Code = 55(for Java) * = 1325 or KLOC

Cost Estimation (Cont.) COCOMO I model  Effort = 3.2 * (Size) 1.05  Effort = 3.2 * (1.325) 1.05  Effort = 4.3 person-months  Time = 2.5 * (Effort) 0.38  Time = 2.5 *  Time = 4.35 months
