Comparative study and performance analysis of incentive compatible routing protocol for two-hop delay tolerant networks

Abstract

Many routing protocols try to identify the complete route from source to destination first and then transfer the data. Sometimes, identifying the instantaneous end-to-end paths may be difficult. In such cases, the routing protocols must take a store-carry-forward approach. Delay Tolerant Networks (DTNs) are such networks which uses the store-carry-forward approach in order to address the issue of lack of continuous network connectivity which is the most common problem in heterogeneous networks. Routing is the major issue for DTNs describing their overall performance. Many flooding and forwarding based routing protocols came into existence and showed their performance by considering different aspects like buffer size of the node, bandwidth, delivery probability, number of hops and energy consumption. In our work, the performance of Incentive Compatible Routing Protocol for two-hop delay tolerant networks is evaluated and compared with the performance of Epidemic Routing Protocol by considering the parameters like: Energy Balancing Factor, Routing overhead, Residual energy, Network Life time ratio, Number of alive and dead nodes and End-to-end delay.
