Abstract
In wireless sensor network, how to quickly match the real-time changing network and reduce the energy consumption in the topology discovery process has been a hot research topic, especially in the network with a large amount of mobile nodes. This paper proposes an improved mobile agents topology discovery (IMATD) protocol for software-defined wireless sensor network (SDWSN). This protocol uses mobile agents (MA) to quickly and efficiently go through each node in the network and collect their topology-related information so that each node can obtain the entire network's topology information. And the mobile agents report and update collected topology information to the controller periodically, so the controller can achieve efficient network management. The simulation results show that the proposed protocol can effectively reduce topology discovery convergence time, reduce topology discovery energy consumption, and balance node energy distribution of the entire network.
