Based On The IPv6Address Automatic Of Wireless Sensor Network

Wireless sensor network, the future will go into all aspects of life, if each node in the wireless sensor networks can be connected to the Internet, so that the user or host will directly from the nodes in the wireless sensor network data acquisition. the wireless sensor nodes can be carried by a user or host directly manipulated, for wireless sensor network application will be more extensive, but the IPv4address now is depleted, it cannot meet the requirements of wireless sensor nodes at the same time many, the maturity of IPv6technology, together with the address number, suitable for use in wireless sensor networks, but now most of the IPv6address configuration method is mainly used in mobile ad hoc networks, the wireless sensor network, study is few in the wireless sensor network, in order to make any node can connect to the Internet, this thesis designs a protocol WSNACP (Wireless Sensor Network Automatic Configur-ation Protocol), the protocol in the wireless sensor network can be completed on the IP node address configuration. The WSNACP protocol consists of4states, respectively, is a new node> agent node、 common node and failure node, the different condition, different tasks and responsibilities, new nodes that does not have a legitimate IP addresses to nodes. there are generally two kinds of situations, one is just to join a network node, a network. Node duplicate address, then request assigns addresses to nodes. The new node in the network to apply for IP address, at the same time the new node has a detection network address the role of conflict; the agent node is the main distribut-ion node address, and management address allocation table, and forwards the data function; common node is transmitting data, assist the agent node to complete the new node address configuration, as well as to repeat address detection task; failure node is a node for a variety of reasons from the network is temporarily not to recover the IP address of the node. In this thesis, the detailed design of IPv6address structure, as well as the protocol configuration address needs all kinds of package, for a variety of state of the node data transceiver detail design. Node through mutual cooperation between different state reached automatically assigned IP address, the protocol is robust to fusion duplicate address detection function, at the same time protocol also has the address of the function recovery.Based on the WSNACP to achieve, with the OPNET (Optimization Performance Network Engineer Tool) simulation software on the agreement to carry out the simulation test, and analyzes the protocol performance index. Through the OPNET network simulation, the WSNACP protocol address configuration repetition rate lower than the traditional address allocation protocol, duplicate address detection is also relatively traditional address allocation protocol overhead is lower.
