... node in the network is linked as a chain. In each round, a node in the chaining structure is chosen as the chaining head. Both ends of the chain then start transmitting data to adjacent nodes in ... transmission between the sensor nodes. Most of the existing methods consist of preselecting m keys from a key pool and forming a key chain. Then, the sensor nodes make use of the...
