Design And Implementation Of Location-based IPv6 Network Wireless Routing Protocol

As there are more and more terminal devices gaining access to the wireless network,routing policy is vital to the packet diversion.Currently,researches on wireless routing protocol are more partial to the researches on routing hop,link status,etc.,as these different types of parameters are of great significance to the researches on wireless routing protocol.With the rapid development of Internet,there are more and more terminal devices supporting wireless connections,as the allocating resources of required IP addresses have been continuously expanding.The allocating resources of IPv4 addresses have already become exhausted,so there are more and more service applications turning to support the IPv6 addresses.Based on the advantages of IPv6 addresses in their lengths,it is considerable to give much more essential attributes to the IP addresses.Furthermore,due to the increasing number of router devices accessing the wireless network,location information has become a key factor which needs to be considered.Based on the researches on wireless self-organizing network routing protocol,the paper put forwards the routing protocol in combination with the model of IPv6 address structure,and designs the corresponding routing node prototype system specific to the situation of intercommunication between any two nodes which needs to be completed through multi-hop forwarding.This system can generate the forwarding path in the process of route discovery and route selection according to the location information in IPv6 address structure.The main tasks of the paper include two aspects specifically.On the one hand,the paper put forwards a IPv6 address structure model based on the location information,which makes the plane coordinate mapped to the inner IPv6 address structure according to the approach of conversion of number systems,designs the wireless routing protocol in combination with this model,and completes several processes including neighbor discovery,route discovery as well as route selection.On the other hand,the paper designs the routing node prototype systems running the above-mentioned protocols,including LuCI interface configuration,data discovery layer,data calculation layer,data processing layer and data persistence layer.This system acquires the corresponding location information through the wireless mesh networking according to the destination address type of received packets,generates the forwarding path of destination node and store through the protocol processing.Experimental results show that the proposed IPv6 address structure model can be effectively applied to the designed wireless routing protocol,effectively saves the expenses of routing protocol,reduces the proportion of control message in data transmission bandwidth,selects the paths with short wireless links and short time delay for forwarding as far as possible,as there are various spare forwarding paths in convenience of routing switch while there are some changes in the environment of network topology,to ensure the normal forwarding of actual data.
