Energy of Bandwidth and Storage Routing Protocol for Opportunistic Networks

Opportunistic Networks is communication environment which has no stable path. Therefore, in this environment, the routing algorithms are partitioned into two main classes which are metric-based and contact-based. Essentially, contact based algorithms target for a high routing performance and small delay at the same time. However; these protocols consume high resources in terms of Energy, Bandwidth and Storage. Practically, opportunistic nodes such as smart phones and tablets suffer from the limitation of the energy and physical memory. In addition, the environment connectivity instability leads to low bandwidth links. This work proposes a resource concentrate routing protocol for opportunistic networks, named Energy of Bandwidth and Storage Routing Protocol (EBSRP). The energy is considered as a main factor calculated as a function of bandwidth and storage. The proposed EBSRP has its queuing policy calculated as a function of energy ratio. The Simulation results are used to analyze the performance of EBSRP and it is compared with Epidemic using different replication and dropping policies based on energy, bandwidth, and storage. The results show that the proposed protocol has better performance than Epidemic in terms of delivery ratio, delay, and overhead.
