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

Algorithm 2

Connection establishment algorithm.

//SINK: the base station or the data collection unit

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

ID (): identifier of

: distance between N_i and the sink

: no. of nodes to which the sink broadcasts the relation signal

is the node among neighbours to which the relation signal is sent by the sink

//set of nodes in the network except the nodes to which the relation signal is sent by the sink

Condition to be met: (any node in RS)

: the threshold for the number of nodes to validate the report

//index refers to a neighbour of the sink

FOR to do

  relation-propagate ()

//Function used to establish the families in the network.

//index refers to a neighbour of neighbour

relation_propagate ()

()

//if statement refers to the condition that must be met to terminate the family establishment process

if () or ()

    terminate relation_propagate

else

    for every node in neighb_set

    if

      establish relation between and

    end if

    relation_propagate ()

   end for

end if
