An Enhanced Forwarding Method based on Intelligent Water Drops Algorithm in Named Data Network

Although Named Data Network (NDN) has made a bright future in the Internet for high volume of requests by many users, how to send a request package (I - Pkt ) consciously from the consumer to the p roducer and returning the data package (D - Pkt) inversely is still one of its most important challenges. According to the recent limited researches, using service quality parameters beside an optimization algorithm li ke ant colony to find the optimal path has been an appropriate response to solve this problem. Insufficient attention to service quality parameters to find an optimal path is a problem to be focused on. In line with this, this study has addressed forwardin g using the Intelligent Water Drops (IWD) optimization algorithm. In this algorithm, the best possible path based on many parameters related to path quality like cost, delay and number of steps taken by the package (I - Pkt) will be selected. In other words, the water drop movement tries to find the optimal path through the amount of soil collection in the path or the velocity rate. The results of simulating in ndnSIM simulator show that comparing the ant colony, it has been improved in cost parameter on aver age by 23%, in hit ratio parameter by 24% and in hop count parameter by 13%. The general result is increasing service level quality in NDNs.
