Designing a wireless sensor network for ocean status notification system

Abstract

Reliable and energy efficient routing protocols are considered as critical issues of discussion in Wireless Sensor Networks (WSN). In this paper, we proposed a novel scheme based on Wireless Sensor Networks for Ocean Status Notification System (WOSNS) so that the environmental conditions of the oceans can be monitored. According to the proposed approach, all the sensed data in each area will be transmitted to the related cluster head; then, they will be forwarded to the nearest sink. We used two sinks in appropriate positions. We used the proposed Smart Inner Routing Algorithm (SIRA) for routing data from the cluster heads to the related sink. Furthermore, we proposed a Binary Recursive Convergent (BRC) algorithm for aggregating data in each area. Multi-hop delivery was used to conduct the routing operations. We also introduced a Bidirectional Duplicate Elimination Technique (BDET to eliminate the duplicate data of the sinks. Simulation results indicated that the proposed method is better than the other protocols in terms of average delivery ratio, network lifetime and network traffic.
