A GPS Based IP Dynamic Configuration Approach in Mobile Ad Hoc Network

Address dynamic configuration in the IP-based network is often accomplished by the dynamic host configuration protocol (DHCP), however, the mobility of mobile ad hoc network (MANET) nodes always involve unpredictable topology changes. Previous works on IP address in ad hoc network assumes that all the address is configured statically by the centralized administration. However, as with the rapid development of wireless network, there are not enough IP addresses available to identify each individual user. DHCP can not be utilized in a mobile ad hoc network due to the lack of any centralized DHCP server in distributed dynamic environment. There are also two typical enhanced solutions for dynamic host configurations, i.e., MANETConf and Quorum approaches. Consider the information of geographical position that from a GPS, we proposed a simplified configuration protocol to reduce controlling overhead and the associate traffic loss during handover period. Extensive environments are implemented comparing the performance of the three approaches. The results shown that the GPS based configuration is more efficient than the traditional methods.
