IRS: Incentive Based Routing Strategy for Socially Aware Delay Tolerant Networks

Delay Tolerant Networks (DTNs) are special class of networks which can work in the challenged environment where conventional networks fail to work. The main reason for the failure of conventional or traditional network is absence of end-to-end path. If end-to-end path does not exist traditional network can not work, but in modern day to day life computer network and internet is an essential part of our life. Thus, DTNs is the most probable solution for challenged area where traditional networks can not provide services. In real life everyone carries smart phones and handheld devices, these devices can play important role in relaying data for DTNs i.e, social DTNs. Socially aware (DTNs) are human-driven DTNs in which nodes act similar to human behavior. They can act selfishly to save their resources and deny to relay packets. For the solution of this problem we have proposed IRS, incentive based routing strategy. In this approach intermediate nodes can participate and earn incentives for sacrificing their selfishness.
