On the other hand, when the NWMS receives information about the misbehaving node B from the source and destination nodes respectively, the NWMS creates a row in its MNL including the sequence number=1, node ID=NID_0002, and weight=1 as shown in Table 2.
If the source node S receives a NWARN(D, B) message, it sends an ACK message to the destination node to notify that it received it normally, and the source and destination nodes report node B to the NWMS.
8 shows the operating procedure of the NWMS received information regarding the suspicious node from the source and destination nodes.
In the proposed routing protocol, the source and destination nodes report nodes with false accusations to the NWMS, which is an upper layer' node.
Since the NWMS has private keys for the whole nodes, it could compare the path identification value with the address chain to identify the false report action by collusion of two nodes.
The NWMS checks the weight of the corresponding node, and if it is not 0, it decreases 0.
In addition, it shows the best performance because it could continuously manages the nodes with abnormal activities through the NWMS even if they move.
Packets additionally generated are the NWARN packet with which the destination node reports the malicious nodes with false accusations to the source node as a unicast, the ACK packet with which the source node informs the normal receiving of the NWARN packet to the destination node, the NWARN packet with which the source and destination nodes report the malicious nodes to the NWMS, and the packet that the NWMS broadcasts to all the nodes in the area.
size], the time of the simulation is T, and the average number of nodes included on the path from the reporting node to the NWMS is n, then the overhead V for transmitting the NWARN packets and the acknowledged ACK packets between the source and destination nodes is as given in Eq.
the overhead U generated when the source and destination nodes report the suspicious nodes to the NWMS is as in Eq.
the overhead B generated when the NWMS broadcasts the nodes with abnormal activities is as in Eq.
