One problem with DHCP is connectivity, where connected devices can cause saturation of the IP address range. 60% of the devices connected to a wireless network occupy an IP during the entire lease time without being used due to its mobility between the available networks. Therefore, a unified configuration in the lease time and the range of IP addresses in each network segment results in inefficient use of IPs. In this work, after analyzing the connectivity behavior and performance of DHCP of the west zone of the Universidad Autónoma de San Luis Potosí, we proposed the development of a dynamic optimization model of DHCP for the allocation of IP addresses using an adaptative algorithm implemented in free software as a solution to the saturation problem in this University. The results show an improvement of connectivity in wireless networks by 98% by adjusting their lease times and by 100% by adequately managing the distribution of the IP address range in each network segment. This adaptative algorithm functions as an intermediate agent that inspects the behavior and performance of DHCP and automatically searches for an immediate solution to the IP address saturation in the subnet.References
