Detection and Counter Measure of Packet Misrouting by GPS-Free Positioning of Ad-Hoc Nodes

Algorithm 4

Behavioural data Collection.

	Input: n = 0, N, A,CHN, LTN
	N: Number of nodes participated in cluster.
	A: Attacker node
	CHN: Cluster head node
	LTN: Local truster node
	Output: resistant to attacker
(1)	Regressive {
(2)	if (the test attacker information is not available in routing table of local-truster node and cluster head node) then
(3)	Release from this practice
(4)	else
(5)	Discover the attitude of attackers’ node = {attackersn}Є N
(6)	Approve action on attackers’ node
(7)	Discover action of attacker
(8)	if (all attacker nodes follow the approve action) then
(9)	The number of attacker’ node increases or decreases.
(10)	Update information into cluster head and local-truster node.
(11)	end if
(12)	n++}
