Abstract
Designing an efficient routing protocol that opportunistically forwards data to the destination node through nearby sensor nodes or devices is significantly important for an effective incidence response and disaster recovery framework. Existing sensor routing protocols are mostly not effective in such disaster recovery applications as the networks are affected (destroyed or overused) in disasters such as earthquake, flood, Tsunami and wildfire. These protocols require a large number of message transmissions to reestablish the clusters and communications that is not energy efficient and result in packet loss. This paper introduces ODCR - an energy efficient and reliable opportunistic density clustered-based routing protocol for such emergency sensor applications. We perform simulation to measure the performance of ODCR protocol in terms of network energy consumptions, throughput and packet loss ratio. Simulation results demonstrate that the ODCR protocol is much better than the existing TEEN, LEACH and LORA protocols in term of these performance metrics.
Highlights
Among many applications wireless sensor networks had been used for incidence respone and disaster recovery
This is because using Eqs. (6) and (7) we find that the average message transmission in opportunistic density clustered-based routing protocol (ODCR) is much lower than that in LEACH and Threshold Sensitive Energy Efficient Sensor Networks Protocol (TEEN) protocols
Each sensor or wireless device joins to a cluster and transmits data packets to the cluster head or if the node is isolated opportunistically forwards data packets whenever encounters another node with higher probability of data delivery to the destination
Summary
Among many applications wireless sensor networks had been used for incidence respone and disaster recovery. This paper introduces an energy efficient and reliable opportunistic density clustered-based routing protocol (ODCR) for emergency/disastrous situations.
