A range based node localization scheme with hybrid optimization for underwater wireless sensor network

Abstract

A great interest among researchers to establish Underwater Wireless Sensor Networks (UWSN) with mobile nodes have been created in recent past because of numerous potential applications in aquatic science. In comparison of radio communication, acoustic communication has lower bandwidth and larger propagation delay. This enacts additional restrictions on any localization algorithm. Existing range-based approaches involve increased localization latency and error even with large deployment of anchor nodes. Some of the optimized localization techniques involve higher energy consumption and cost. In order to solve these issues, a hybrid optimized localization technique is proposed that can accurately localize mobile nodes in UWSN. In this algorithm, a fitness function is concluded based on the number of hops from the anchor node, Time of Arrival (ToA) distance estimation error and transmission delay. In comparison of existing localization techniques, proposed algorithm helps in reducing the energy consumption, localization error, localization delay and localization cost and experiment results proved the same.

“…Nain et al 42 and Kumar et al 43 have focused on localization techniques in UWSN. In Chaudhary et al, 44 an extensive review of node deployment and data collection challenges are proposed.…”

Underwater Cross Layer Protocol Design for Data Link Layer: Stochastic Network Calculus

“…Once the node is dead, the next node gets active for further communication by sharing the beacon frame. There are many localization algorithms available in various surveys [32] [34]. For example, the hierarchical localization technique [41] is suitable for the underwater coral farming application, shown in Figure 4.…”

TAEffect: Quantifying interaction risks in trust‐enabled communication systems

“…several evaluation metrics, such as energy consumption, expected transmission count, and congestion avoidance. Toward the localization problem of mobile sensor node under the influence of shipping movement, fishing movement, and tectonic plates movement, Nain et al 59 proposed a range‐based scheme to achieve the location latency reduction and accuracy with hybrid optimization technique for the underwater sensor networks. Seen from the above work, we know that the wireless sensor‐based communication systems confronted many influential factors, such as shipping/fishing/tectonic‐plates movement, energy‐shortage, and communication interruption.…”
