A Key Pre-distribution Scheme for Wireless Sensor Networks Using Cell Model
Liu He · Microelectronics & Computer · 2006
In order to achieve secure communication between nodes in wireless sensor networks, the messages between nodes must be encrypted before sent. Nodes can be close to predict target point when special deployment knowledge is used, and can also be grouped by the geography knowledge. So keys can be distributed to nodes in the same group and neighbor groups according to the location information. Key pre-distribution using cell model will provide high efficiency in key distribution and sharing, and will also reduce the cost of distribution and maintenance. This scheme can substantially improve the networks' security and connectivity.
