Abstract: In the mobile ad hoc networks, due to the multi-hop of the data, the limited bandwidth and the dynamic changes of the network topology, the network performance is hindered. This paper proposes a Load-based Queue Scheduling algorithm (LBQS) for MANET. Nodes thoroughly consider their own load states when forwarding packets. The priorities of packets are assigned according to the current node’s load level. When nodes are leisure, they should help other nodes to construct route first. In order to avoid network transmission delay increasing and packets losing, nodes should delay or forbid the construction of new route passing through them when their load level is high. The simulation results show that LBQS algorithm can effectively decrease the network transmission delay and promote the network throughput to a certain extent.
