Abstract:

In the scene with multiple sensing tasks in wireless sensor network, an Adaptive Capacity Control Strategy (ACCRP-MST) is proposed to use intermediate nodes efficiently. ACCRP-MST finds multiple node-disjoint paths for each source-sink pair by taking into account the tradeoff between residual energy and hop count and achieves traffic load balance. Then it uses the Multi-path Source Routing (MSR) protocol to report the acquired data in order to save the storage and computing cost of the intermediate nodes. Simulation results based on NS-2 show that the proposed ACCRP-MST outperforms several other energy-efficient routing protocols by increasing the network lifespan and communication reliability and efficiently enhancing the overall performance of the network.
