Abstract—Underwater Acoustic Sensor Networks (UASN) consisting of sensor nodes and underwater gateways (routers) have wide variety of applications which include environmental monitoring, scientific exploration, surveillance etc. Ad hoc nature of these networks in terms of mobility due to water current pose challenges in topology management. Neighbor discovery is an important issue in topology management which is required to auto configure the node addresses, and establish communication links among the nodes to perform routing management. The media access control (MAC) protocol may utilise the neighbor discovery information to decide the accessibility of the media by nodes so as to reduce the delays and increase throughput. Thus there is a necessity of integrating MAC protocol and neighbor discovery mechanism in UASN. In this paper, we describe the architectural elements of neighbor discovery protocol module implementation in NS3. The implementation models surface and underwater interactions, mobility, and channel conditions required for network level simulation. The module implements two main classes namely, NeighborDiscoveryProtocol and NeighborDiscoveryCache, which enable the protocol interactions. We present the preliminary results from implemented module using NS3.
