Abstract
End-to-end reliability for Wireless Sensor Network communications is usually provided by upper stack layers. Furthermore, most of the studies have been related to star, mesh, and tree topologies. However, they rarely consider the requirements of the multi-hop linear wireless sensor networks, with thousands of nodes, which are universally used for monitoring applications. Therefore, they are characterized by long delays and high energy consumption. In this paper, we propose an energy efficient link level routing algorithm that provides end-to-end reliability into multi-hop wireless sensor networks with a linear structure. The algorithm uses implicit acknowledgement to provide reliability and connectivity with energy efficiency, low latency, and fault tolerance in linear wireless sensor networks. The proposal is validated through tests with real hardware. The energy consumption and the delay are also mathematically modeled and analyzed. The test results show that our algorithm decreases the energy consumption and minimizes the delays when compared with other proposals that also apply the explicit knowledge technique and routing protocols with explicit confirmations, maintaining the same characteristics in terms of reliability and connectivity.
Highlights
Many industrial applications require the deployment of sensor networks that follow straight lines. In applications such as monitoring water, oil, or gas pipelines, roads, tunnels, borders, etc., wireless communication technologies provide clear advantages for the creation of highly reliable and self-healing industrial systems that can respond to new events [1]. This problem has been studied in recent years, and different authors proposed the deployment of Linear Wireless Sensor Networks (LWSN) [2], characterized by sparse node deployment along the linear infrastructure
WSNs have been widely studied, and there are different protocols that have been designed to support a wide range of network topologies, for example, 6LowPAN and ZigBee, which can use IEEE 802.15.4 for the lower layers
This paper presents a new proposal for sensing linear infrastructures with WSN to send alerts
Summary
Many industrial applications require the deployment of sensor networks that follow straight lines. In LWSNs, nodes may be placed in a thin (one dimension, forming a line) or thick (two or three dimensions around a line) configuration, and can have identical (one-level) or differentiated (multiple-level, creating a hierarchical network) functionalities [9] In the applications such as pipeline monitoring, a thin one-level network is cheaper and simpler to build and maintain, this being the configuration considered in this paper to propose solutions for the minimization of energy consumption and delays (while maintaining reliability and connectivity) in LWSNs. a direct transposition of classical protocols on LWSN is not efficient, as linear topologies are the worst cases for hierarchical networks (spoilage) and for stochastic distribution (time for reparation) [10].
