An Efficient Strategy for Enhancing Robustness and Immunization in Wireless Sensor Networks

Free registration required

Executive Summary

To provide cost-effective protection for sensor networks, the authors introduce an immunization method where the percentage of required vaccinations for immunity are close to the optimal value of a targeted immunization scheme. Their strategy retains the advantage of being purely local, without the need of knowledge on the global network structure. The method consists of selecting the vertex with the highest degree within a distance d and asking for a neighbor that has more links than himself or more than a given threshold and immunizing him.
