Pain Modelling In An Artificial Immune System Based Manet

The dynamic topology of a Mobile Ad Hoc Network (MANET) can introduce operational performance constraints. Cells in the human body use pain to indicate a sense of stress or discomfort. This paper conceptualizes pain in a MANET. As MANET is a collection of mobile nodes that may be acting as a source, destination or relay there is an inherent instantaneous variability in the MANET, and this affects performance. At times, nodes may not be willing to consume energy to act as a relay, which would be for the benefit of the other MANET nodes, and this action reduces the MANET performance thereby introducing the concept of pain. We consider critical parameters like trust, effective node energy and the energy cost associated with each packet at a node. In this paper, we model MANET performance as pain utilizing the principles of an Artificial Immune System (AIS). In the Human Immune System (HIS), cells can distinguish between a variety of problems including foreign body attacks and cellular senescence. This paper presents a pain model and imparts pain reduction to stabilize the network using an AIS based approach that mimics the HIS.
