Nature inspired algorithms are common in routing and security in mobile wireless sensor networks (WSN). While most of the existing algorithms are bio-inspired, chemistry inspired security algorithms are rare. Chelation is a chemical process where a molecule forms two or more bonds with an atom or a molecule to hold it strongly. Analogous to this chemical process, a chelating node in a mobile WSN is defined as a mobile node that forms more than one logical association with another node. The paper uses mobile polydentate chelating node, which uses multiple heterogeneous logical linkages with a rogue node, to ascertain non-friendly behavior of a node to ensure detection and removal. The multiple linkage processes are based on challenge-response using public key infrastructure, integrity of routing algorithm, routing table fidelity and data path tracking. This n-dentation ensures detection of captured nodes as well as nodes planted by adversaries. The paper demonstrates the applicability of this process for a mobile WSN-based border surveillance where the number of attacks is high and varied in its pattern. The proposed approach reduces false negative as well as false positive detection by its n-modular redundancy. Simulation results are presented to illustrate the effectiveness of this scheme.
