Energy Efficient Data Dissemination in Multi-UAV Coordinated Wireless Sensor Networks

Abstract

With the requirement of better connectivity and enhanced coverage, collaborative networks are gaining a lot of popularity these days. One of such collaborative networks is formed between the wireless sensor networks (WSNs) and the unmanned aerial vehicles (UAVs). WSNs comprise static nodes arranged in a flat grid topology which may be randomly deployed or by some particular distribution. With the sensors operating on batteries, WSNs face a crucial issue of energy depletion during network operations. Integration of WSNs with UAVs can provide a solution to this excessive utilization of energy resources. UAVs provide a maneuvering support by playing a pivotal role of a manager node in these networks. However, integration of these networks demands an improved approach for data dissemination for effective utilization of network resources. For this, we propose a new data dissemination approach, which utilizes the attraction properties of fire fly optimization algorithm to provide energy efficient relaying. The proposed approach provides continuous connectivity, better lifetime, and improved coverage in the UAV coordinated WSNs. The performance of the proposed model is presented in terms of significant gains attained for parameters, namely, throughput, coverage, mean hops, lifetime, and delays, in comparison with the EEGA, ERIDSR, and I-ERIDSR approaches.

An Efficient Mobility Model for Improving Transmissions in Multi-UAVs Enabled WSNs

“…Nature-based algorithms help in performing cooperative rendezvous and efficient task allocation for coordinated UAV networks [4]. A cooperative ground to air surveillance mechanism that employs UAVs for broad coverage and ground nodes for a detailed zoomed in picture of the area under surveillance is presented in [5][6][7]. The various UAV application scenarios are presented in Figure 1.…”

“…The various UAV application scenarios are presented in Figure 1. The multi-hop characteristics of WSN data transmission were replaced by direct communication between UAV and sensor nodes where UAVs served as sinks [7,8]. Alongside available performance gains, the network formation and setting up way-points for UAV movements are an issue.…”

“…Cellular network-based air-to-ground links and unmanned aircraft system (UAS)-backbone systems, communication aware sensor distribution, etc are some of the promising aspects of the UAV systems. 2,3 The crucial step towards UAV networks is the development of sustainable multi-UAV environments. National regulations, routing, path planning, quality of service (QoS), integration with Global Information Grid (GIG), mobility control, coordination, and standardization are the steps required for efficient migration towards flying networks (multi-UAV).…”
