In this paper we propose the first proactive co-operative link self-healing (POLISH) scheme, in which the secure link compromised in WSNs automatically self-heals with time, without the help of a server. Our scheme updates a secure link using the random data transmitted from the neighboring sensor nodes, based on the idea of the POSH scheme. It is necessary to newly take the security of a link between sensors into consideration in our scheme since such security is not considered in the POSH scheme. We conduct analytical evaluation and a simulation experiment for our scheme, and the results indicate that our scheme is very effective in self-healing.
