To improve the performance of Ad hoc on-demand multipath
distance vector (AOMDV) protocol, we proposed NS-AOMDV which is
short for “AOMDV based on node state”. In NS-AOMDV, we introduce node state to
improve AOMDV’s performance in selecting main path. In route discovery process,
the routing update rule calculates the node weight of each path and sorts the
path weight by descending value in route list, and we choose the path which has
the largest path weight for data transmission. NS-AOMDV also uses the
technology of route request (RREQ) packet delay forwarding and energy threshold
to ease network congestion, limit the RREQ broadcast storm, and avoid low energy
nodes to participate in the establishment of the path. The results of
simulation show that NS-AOMDV can effectively improve the networks’packets
delivery rate, throughput and normalized routing overhead in the situation of
dynamic network topology and heavy load.
