Abstract
Due to lack of features of traditional network characteristics, DTN becomes one of the promising research paradigms of wireless network. As there are intermittent connectivity and store-carry-forward features, end-to-end acknowledgement is not possible. DTN is also named as ‘opportunistic network’. But interestingly, intermediate nodes may always not behave fairly. Sometimes, due to limited resources (bandwidth and memory) intermediate nodes may behave ‘selfish’. Intermediate nodes may also behave unfairly to next hop node intentionally. This behaviour is known as ‘misbehaving behaviour’. Recent studies on ‘selfish node’ and ‘misbehaving node’ show us the negative impact on network performance (delivery ratio, delivery cost, delivery latency). So we design a slightly new concept inspired by real-life application in our paper showing the positive aspect of the involved nodes in the network. Apart from participating in data forwarding, node may behave as ‘traffic node’ trying to show the right path towards destination.
