Rank-Based Report Filtering Scheme (RRFS) for Verifying Phoney Reports in Wireless Sensor Networks

Algorithm 3

Guest key generation.

SN: the set of all nodes in the sensor network-SINK

//neighbour of the sink

DN and UN are the corresponding downstream node and upstream node.

DN sends the initiate signal to the UN in RN
