This paper explores the benefits of cooperative diversity for a linear arrangement of wireless sensor network (WSN). Such arrangement is typical for instance in the case of pipeline monitoring. The focus in this work is restricted to the Amplify-and-Forward (AF) protocol at the relay sensor node where a proper lightweight combining strategy is considered at the receiver. A linear 3-node arrangement of WSN network is considered in the simulation. Substantial gain was observable upon deploying our cooperative scheme. It is evident that the distance between sensor nodes plays a role in dictating the overall system performance. Though they both fall under the same paradigm, there can be a remarkable difference between a fully-cooperative and a partially-cooperative relay node. This motivated us to introduce the reliability of cooperation for the relay sensor node, and study its impact on the system performance. Simulation results make it clear that the cooperation reliability of the relay node can excruciately impact the system performance. Proper measure needs to be taken to account for this vulnerability in the cooperative scheme.

wireless sensor networks have been applied in diverse applications, from facility monitoring to localized event surveillance, e.g., in power distribution grids of developing regions where traditional cables are not feasible. linear wireless sensor networks are employed in such situations, where nodes link through lossy tandem links. sensors generate and send data packets through intermediaries to reach network endpoints, where gateways forward aggregated data to a central server. Our previous research introduced a TDMA-based framework to ensure stable, cost-effective deployment, optimize delivery efficiency, and feature a proactive loss recovery mechanism in lossy links. However, as link loss increases, maintaining a high successful delivery probability that all packets from all nodes to the server becomes more challenging. Besides, the number of packets generated at sensors can fluctuate and sometimes exceed downstream link capacity, resulting in unrecovered packet losses. This paper investigates the benefit of using network coding schemes to enhance data transmission reliability in linear multi-hop wireless sensor networks, especially in a high link loss rate and packet fluctuation situations. The simulation results show a significant improvement in overall successful delivery probability and fairness (small deviations of success delivery probability among nodes) compared to the previous method in scenarios with a high link loss rate and moderate packet fluctuation.

The distributed management of residual energy among sensor devices within wireless sensor networks is a crucial technique that can be leveraged to maximize network lifetime. This paper proposes an approach towards this goal based on an ultra-low-power Medium Access Control (MAC) protocol and a geographical multi-hop routing protocol according to a given metric. The best node for the next hop is selected as a function of the minimum hop count and a link cost function. This is done in a manner which minimizes the overall energy consumption of the network, while balancing the load according to the residual energy at each node. To achieve this, the cost function accounts for residual energy, free buffer size, and link reliability to neighbouring nodes. It is designed to balance energy consumption, network life and QoS requirements in terms of end-to-end delay and reliability. Simulation results are presented, obtained through the Castalia framework based on the Omnet++ simulator. These results demonstrate the viability of the proposed scheme through observation of key performance parameters as a function of consumed energy, active time ratio of each node, and packet delivery ratio.

This paper compares the energy consumption used for communication in the special case of a wireless sensor network that is deployed linearly over a long distance to monitor assets such as transmission lines or pipelines. A model for energy consumption is developed based on a suitable network architecture for a linear wireless sensor network (WSN). Using the model, the energy consumption of networks based on two popular wireless communication protocols, LoRaWan and Zigbee, is compared. The results show LoRaWan has significantly better energy efficiency than ZigBee for a linear WSN.

In a multi-hop wireless sensor network with a convergecast communication model, there is a high traffic accumulation in the neighborhood of the sink. This area constitutes the bottleneck of the network since the sensors deployed withing it rapidly exhaust their batteries. In this paper, we consider the problem of sensors deployment for lifetime maximization in a linear wireless sensor network. Existing approaches express the deployment recommendations in terms of distance between consecutive sensors. Solutions imposing such constraints on the deployment may be costly and difficult to manage. In this paper, we propose a new approach where the network is formed of virtual nodes, each associated to a certain geographical area. An analytical model of the network traffic per virtual node is proposed and a greedy algorithm to calculate the number of sensors that should form each virtual node is presented. Performance evaluation shows that the greedy deployment can improve the network lifetime by up to 40%, when compared to the uniform deployment. Moreover, the proposed approach outperforms the related work when complemented by a scheduling algorithm which reduces the messages overhearing. It is also shown that the lifetime of the network can be significantly improved if the battery capacity of each sensor is dimensioned taking into account the traffic it generates or relays.

linear wireless sensor networks (LWSN) are typically used for monitoring infrastructure systems extending over several kilometers, where propagation conditions can be inhomogeneous in different sections of the network. Obstacles and reflecting objects contribute to bit errors in data packets, which take extra time and energy to recover. However, the impact of the inhomogeneities across LWSN sections on the time and energy performance of the entire network remains underreported. In addition, conventional methods of building LWSN by distrib-uting relay nodes among inhomogeneous sections have failed to balance operability and energy efficiency criteria. This article examines the models of time and energy loss in LWSN sections showing different signal fading, represented by the Rician K-factor in the expressions for the bit error probability. On the basis of the dependences of time losses on inter-node distances, algorithms for deploying a heterogeneous LWSN are pro-posed according to the criterion of minimizing end-to-end network delay without restrictions on hardware and energy resources or when distributing a limited number of nodes. As an alternative to the efficiency criterion, we propose algorithms for balancing power consumption in a heterogeneous LWSN at an acceptable level of power loss without limiting the number of nodes or at the lowest level of power loss with a limit on the number of nodes. Experiments were carried out on CC2500 TI node transceivers in five inhomogeneous LWSN sections, where K-factor ranges from 5 to 100, in order to demonstrate the efficiency of the proposed algorithms. Results showed that the end-to-end delay and energy loss can be reduced by 1.36 and 2.4 times, respectively, compared to those in networks with uniformly distributed nodes. To further assess the operability and energy efficiency of the algorithms, a scheme is proposed based on the ratio of normalized concessions in the Pareto region. Addi-tionally, the optimal number of no

In linear wireless sensor network (LWSN) for railway environment monitoring, aiming at the problem that single-hop transmission aggravates the energy exhaustion of nodes and shortens the network lifetime, combining with the requirements on low energy consumption and high real-time of railway environment monitoring, an energy-balanced data transmission strategy for linear wireless sensor network is proposed. Based on the Lagrange multiplier method, it is verified that the energy consumption of non-uniform cluster head (CH) deployment is lower than that of uniform deployment, the CH complete the optimal deployment in a geometric progression, two-sided and the non-uniform manner. Based on this model, the mathematical relationship between the hop counts, CH energy consumption and the network lifetime of K-hop packet transmission strategy is established. Simulation results show that compared with single-hop transmission strategy, the proposed K-hop packet transmission strategy reduces the hop counts and the energy consumption difference of CH and consequently prolong the network lifetime by about 1.6 times, which meets the high requirements of real-time, energy consumption and robustness of the railway environment monitoring network.
