Reliable Adaptive Replication Routing for Wireless Sensor Networks

Abstract

In this paper, we consider the problem of reliable communication, the packet-loss prevention and packet-loss recreation recovery techniques are widely used and have many practical challenges. Hence, we propose a Reliable Adaptive Replication Routing (RARR) Algorithm, here the packet loss replication is accomplished in several hops and End-to-End (E2E) reliability is improved compared to conventional single E2E paths. RARR algorithm is comprised of a link capacity estimator, random disseminator and a replicator. The protocol employs an adaptive neighbor 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 proposed 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.

“…Many works are motivated by search-and-rescue scenarios in subterranean areas (Wang et al, 2014;Zhao et al, 2017;Gomathi et al, 2015;Li et al, 2020;Lindqvist et al, 2022b) where gasses are one of the potential dangers that rescue workers need to consider. Similar rescue scenarios were also of great interest in the recent DARPA Subterranean Challenge (DARPA, 2020), where teams of robots were tasked to search vast underground areas to find and localize objects of interest.…”
