A Survey on Key Pre-distribution Scheme in Homogeneous Wireless Sensor Networks

Abstract

Wireless sensor network(WSN) has a wide range of applications in military as well as in civilian services. Key predistribution is a challenging task in sensor networks. Because the neighbor of a node after the deployment of sensors is unknown. For secure communication, neighbors must posses a secret common key or there must exist a key-path among these nodes. In this paper we have discussed in brief about various key pre-distribution schemes for homogeneous sensor networks and we had analyzed merits and demerits for each of them. Among various schemes a suitable scheme can be chosen based on the requirement and the resource availability of the sensors.
