DOI: 10.1109/CSNT.2013.79. Mobile agents carry services (code, rules, etc.) as their payload and populate a robotic network. They either migrate conscientiously or track pheromones diffused by robots wanting a service.

(Accepted) Operations occurring at every step at each node: AtNodeQueue 1.If an Agent is at the top of the Intra-node Queue a.CloneifNecessary() b.Compute “NextNode” using Pheromone- Conscientious Algorithm c.Check if movement to the next node is possible. If true goto (d) else goto (3) d.Execute OnDeparture() Method 2.If an Agent is permitted into the Intra-Node Queue a.Execute OnArrival() Method 3.Decrement the Life-time of every agent in the Queue OnArrival() 1.Execute the service if this is the RRS that requested for its service. If true goto (2) else goto (3) 2.Change the Cloning Resource and the Life-time based on rewards 3.Enter into the Intra-Node Queue of the entering Node OnDeparture() 1.Remove from the Intra-Node Queue of the existing Node CloneifNecessary() 1.Find Resource needed for cloning 2.Find the Number of Clones 3.Decrement the Resource based on the Number of clones 4.Create Clones 5.Recharge the Cloning Resource Mobile Agent based Systems (Artificial Being) A MOBILE AGENT FRAMEWORK FOR AN INTERNET OF THINGS 5 Architectures of mobile agent based devices that can populate the Internet of Things Components of the off-board Mobile Agent Framework (MAF) Components of the on-board Mobile Agent Framework (MAF) Functions: Support Migration and Execution of Mobile Agents Maintain neighbour list The envisaged Internet of Things The air-conditioner, vacuum-cleaner and the robot use the MAFs running on dedicated nodes while the printer and web- cam have the same embedded within themselves. Types of Mobile Agents in the Internet of Things 1.SfR (Search for Resource) Agents: These mobile agents are capable of finding a resource in the network as per the specifications of the task to be performed. 2.PaS (Provide a Service) Agents: These mobile agents carry the source code (service) for a task as its payload.
