Concerning the nodes' limited storage in the wireless sensor networks,an enhanced key distribution scheme based on grid was proposed for wireless sensor networks.The paper constructed a new key distribution scheme for key pools and improved the probability of local connectivity.At the same time,the scheme's security was doubly increased by the use of a hash function to protect key information stored in the nodes.Compared with Du's and E-G's schemes,this experimental result shows that the proposed scheme has better performance on the local connectivity probability and security.
