    Wireless sensor networks (WSNs) have been widely recognized as a promising technology that can enhance various aspects of structure monitoring and border surveillance. Typical applications, such as sensors embedded in the outer surface of a pipeline or mounted along the supporting structure of a bridge, feature a linear sensor arrangement. Economical power use of sensor nodes is essential for long-lasting operation. In this paper, we present wireless High-Level Data Link Control (HDLC) a novel approach to energy-efficient data routing to a single control center in a linear sensor topology. Applying a standard data layer along with a time division multiple access (TDMA)-based Medium Access Control (MAC) and time synchronization technique specifically designed for the linear topology, we address the interoperability problem with guaranteed energy efficiency and data link performance in linear sensor topology.Peer Reviewe

    [EN] Wireless sensor networks (WSNs) are becoming one of the demanding platforms, where sensor nodes are sensing and monitoring the physical or environmental conditions and transmit the data to the base station via multihop routing. Agriculture sector also adopted these networks to promote innovations for environmental friendly farming methods, lower the management cost, and achieve scientific cultivation. Due to limited capabilities, the sensor nodes have suffered with energy issues and complex routing processes and lead to data transmission failure and delay in the sensor-based agriculture fields. Due to these limitations, the sensor nodes near the base station are always relaying on it and cause extra burden on base station or going into useless state. To address these issues, this study proposes a Gateway Clustering Energy-Efficient Centroid- (GCEEC-) based routing protocol where cluster head is selected from the centroid position and gateway nodes are selected from each cluster. Gateway node reduces the data load from cluster head nodes and forwards the data towards the base station. Simulation has performed to evaluate the proposed protocol with state-of-the-art protocols. The experimental results indicated the better performance of proposed protocol and provide more feasible WSN-based monitoring for temperature, humidity, and illumination in agriculture sector.This work has also been partially supported by the European Union through the ERANETMED (Euromediterranean Cooperation through ERANET joint activities and beyond) project ERANETMED3-227 SMARTWATIR.Qureshi, KN.; Bashir, MU.; Lloret, J.; León Fernández, A.

    Wireless sensor networks are networks of tiny sensing devices for communicating in using wireless technology. Wireless sensor networks are deployed in scenarios where any plant information should be available for industrial control applications. Cross-layer interaction is most important factor to gain maximum efficiency and also able to provide difficult interaction among the layers of the protocol stack. Hence to achieve this is challenging issue because latency, energy and reliability are at odds, and also resource constrained does not support complex algorithm. Wireless sensor networks have many protocols. In this paper Breath protocol is proposed for industrial control application .To minimizing energy consumption in network breath is designed for WSNs by which nodes attached to plants must carry information via through multi hop routing to sink. To optimize energy efficiency the protocol is based on randomized routing, medium access control, and duty-cycling. Alternate model of breath protocol ensures a long lifetime of the network by making effective distribution of workload in sensor nodes. Hence it shows as a good terminology for efficient, timely data gathering for industrial control applications. DOI: 10.17762/ijritcc2321-8169.15032

    Efficient Retransmission QoS-Aware MAC Scheme in Wireless Sensor Networks

    In this paper, an Efficient Retransmission Random Access Protocol (ERRAP) is designed that combines scheme of collision avoidance and energy management for low-cost, short-range wireless radios and low-energy sensor nodes applications. This protocol focuses on efficient Media Access Control (MAC) schemes to provide autonomous Quality of Service (QoS) to the sensor nodes in one-hop QoS retransmission group in WSNs where the source nodes do not have receiver circuits. These sensor nodes can only transmit data to a destination node, but cannot receive acknowledgement or control signals from the destination node. The proposed scheme ERRAP provides QoS to the nodes which work independently on predefined time by allowing them to transmit each packet an optimal number of times within a given period. Our simulation results demonstrate the superiority of ERRAP scheme which increases the delivery probability and reduces the energy consumption

    Efficient And Secure Key Distribution Protocol For Wireless Sensor Networks

    Modern wireless sensor networks have adopted the IEEE 802.15.4 standard. This standard defines the first two layers, the physical and medium access control layers; determines the radio wave used for communication, and defines the 128-bit advanced encryption standard (AES-128) for encrypting and validating transmitted data. However, the standard does not specify how to manage, store, or distribute encryption keys. Many solutions have been proposed to address this problem, but the majority are impractical in resource-constrained devices such as wireless sensor nodes or cause degradation of other metrics. Therefore, we propose an efficient and secure key distribution protocol that is simple, practical, and feasible to implement on resource-constrained wireless sensor nodes. We conduct simulations and hardware implementations to analyze our work and compare it to existing solutions based on different metrics, such as energy consumption, storage overhead, key connectivity, replay attack, man-in-the-middle attack, and resiliency to node capture attack. Our findings show that the proposed protocol is secure and more efficient than other solutions

    TKP: Three level key pre-distribution with mobile sinks for wireless sensor networks

    Get PDF
    Wireless Sensor Networks are by its nature prone to various forms of security attacks. Authentication and secure communication have become the need of the day. Due to single point failure of a sink node or base station, mobile sinks are better in many wireless sensor networks applications for efficient data collection or aggregation, localized sensor reprogramming and for revoking compromised sensors. The existing sytems that make use of key predistribution schemes for pairwise key establishment between sensor nodes and mobile sinks, deploying mobile sinks for data collection has drawbacks. Here, an attacker can easily obtain many keys by capturing a few nodes and can gain control of the network by deploying a node preloaded with some compromised keys that will be the replica of compromised mobile sink. We propose an efficient three level key predistribution framework that uses any pairwise key predistribution in different levels. The new framework has two set of key pools one set of keys for the mobile sink nodes to access the sensor network and other set of keys for secure communication among the sensor nodes. It reduces the damage caused by mobile sink replication attack and stationary access node replication attack. To further reduce the communication time it uses a shortest distance to make pair between the nodes for comunication. Through results, we show that our security framework has a higher network resilience to a mobile sink replication attack as compared to the polynomial pool-based scheme with less communication tim
