Research of neighbor discovery for IPv6 over low-power wireless personal area networks

The Ipv6 neighbor discovery protocol is unable to meet the networking and address configuration requirements of the nodes in the wireless sensor network (WSN). To address this problem, the 6lowpan network architecture is presented in this paper, and based on the architecture, a method for configuring addresses of the 6lowpan nodes and a basic process for interaction during neighbor discovery are proposed. A context management and distributing strategy is also proposed to expanded 6lowpan domain, providing an approach to the standard protocol RFC6775. Simulation results show that the proposed 6lowpan neighbor discovery protocol is highly feasible and effective.
