In Mobile Ad-hoc Networks if forwarding nodes have high mobility, there are more chances to make local topology inaccuracy. If the node involved in the forwarding path moves frequently then there is the situation of link failure which leads to packet loss. Hence it is required to select the nodes with low mobility which means selection of node as forwarder based on its mobility. Mobility based forwarding node selection scheme improves the routing performance. Source node predicts the distance of each neighbor from itself at particular time (t) using the current location of neighbor and speed of the neighbor. After certain time (t+T) it predicts the distance again using the current location of neighbor. In both situations if the node comes under neighbor status then it is highly stable neighbor. To apply this routing scheme, distance between destination and highly stable neighbors are calculated. The neighbor which is having the minimum distance is selected as forwarder. If there is tie between the nodes then the node which is having high willingness value become forwarder node. This willingness value can be calculated using power, coverage and reliability of the node. The higher values there are more chances to become forwarder node. The message confidentiality and integrity has also being implemented using RSA asymmetric key encryption algorithm. The node authentication is also implemented using Aggregate Signature algorithm. The simulation result shows how it can reduce broadcasting redundancy and improves the packet delivery ratio.
