Reliable Adaptive Replication Routing for Wireless Sensor Networks

In this paper, we consider the problem of reliable communica-tion, the packet-loss prevention and packet-loss recreation recov-ery techniques are widely used and have many practical chal-lenges. Hence, we propose a Reliable Adaptive Replication Rout-ing (RARR) Algorithm, here the packet loss replication is accom-plished in several hops and End-to-End (E2E) reliability is im-proved compared to conventional single E2E paths. RARR algo-rithm is comprised of a link capacity estimator, random dissem-inator and a replicator. The protocol employs an adaptive neigh-bor knowledge scheme which differentiates the density of nodes in the deployed scenario and hence reduces the overheads compared to the existing Proliferation Routing scheme. Simulation results demonstrate the effectiveness of this scheme and show that the pro-posed protocol is a feasible solution to increase the service quality (i.e., E2E transmission success rate, energy efficiency) compared with the well-known routing techniques. The proposed protocol is scalable and practical, and it dynamically adapts to the network topology. Keywords
