Objectives: Due to the advancements in the technology, security while transmission becomes a crucial part. So there is a need to design a new protocol that is more efficient than the traditional protocol, and should consider both security and packet delivery ratio along with some other parameters. With this intention, a new technique is proposed which considered the data rates and the security issues.
Methods/Statistical analysis: An improved version of HRARAN protocol is used in order to obtain a secure and reputed transmission in a network which is based on public key cryptography and reputation techniques. Reputation value of a node is used to know whether the node is able to cooperate in a network or not which is calculated by the past behavior of individual nodes. Thus, in such case a cooperative node in the network has highest reputation value. Value in the routing table upgrades after packet reaches at the destination.
Findings: Traditional approach does not perform accordingly in terms of accuracy and packet delivery ratio, which is only 62.3 as compared to the proposed approach in which PDR is high i.e. 76.3. Moreover, PDR defines the number of packet reach at the destination and it can be concluded that in the proposed approach packets reach more in improved HRARAN. Considering another parameter i.e. packet loss in the existing and proposed HRARAN is 754 and 474 respectively which concludes that accuracy of the improved HRARAN is high.
Improvements/Applications: The protocols can be improved by:
• Increasing number of quality parameters in order to selecting the best path.
• Optimization algorithms can be employed for finding out the optimized path for routing.
