Abstract

Link failure and unreachable nodes due to interference from external devices are common problems in WSNs. These interferences can be a major inhibitor to node performance and network stability. In order to tolerate these failures, we propose an immune-inspired self healing system where an individual node can detect degradations in network performance, perform diagnostic tests, and provide automated immediate response to recover the network to a stable state. We evaluate and compare the performance of our approach with other routing protocols on a testbed environment using TelosB hardware motes.
