With the research and application of wireless sensor networks are widely used in the medical field. It is put forward higher requirements for its reliability, flexibility and high efficiency. Changeable and unpredictable characteristics of the medical field environment are major factors that lead to the reliability decline in medical wireless sensor network. Finding a reliable path is an effective...
Disjoint multipath routing is an attractive approach for improving the reliability of data delivery in wireless sensor networks. Recently, the issue for maintaining the robustness and efficiency of the disjoint multipath routing against network failures such as network holes are being studied. Several protocols have been proposed to handle the network failures. However, they cause the large performance...
The main purpose of a sensor network is information gathering and delivery. Therefore, the quantity and quality of the data delivered to the end user is very important. Since the majority of developed applications for WSNs are event-critical applications, achieving reliable data transfer as the main factor of dependability and quality of service seems vital. In this paper, we focus on building a tree-based...
Supporting Quality of Service (QoS) in WSNs is still a largely unexplored research field. The commonly accepted QoS metrics include bandwidth, delay, delay jitter and reliability. Besides, whereas the majority of developed applications for WSNs are event-critical applications, achieving reliable data transfer as the main factor of dependability and quality of service seems vital. In this paper, we...
This paper proposes a reliable an energy efficient routing protocol for transmitting periodic packets on industrial wireless sensor networks. For reliable transmission of periodic packets, the proposed protocol chooses the path has highest end-to-end packet reception rate (e2e_PRR) to transmit data packets. Also, a mechanism is used to reduce the number of control packets. The simulation result has...
Future WSNs are expected to carry different traffic such as voice and video as well as data to serve both real and non-real time applications. Therefore, the reliability and quality of the data delivered to support diverse applications is very important. Also, service differentiation is an essential component of QoS that should be supported by routing protocols. In this paper, we introduce a novel...
This paper proposes a reliable routing protocol on wireless sensor networks based on the well-known AODV routing protocol. The main idea of proposed protocol is to find the route which has the highest end-to-end reliability from the source to the destination based on the hop-by-hop packet reception probability. We consider the end-to-end reliability of a route as the product of hop-by-hop packet reception...
The traditional wireless sensor networks based on minimum hop routing (MHR) protocol have the disadvantage of short stable period of minimum hop gradient field (MHGF), this would lead to the data sinking unreliable easily. In this paper, in order to improve the reliability of data sinking, a minimum hop routing wireless sensor network based on link reliability guaranteed (MHR-LR) is proposed. In the...
In energy constrained wireless sensor networks, it is important that a routing protocol provides network redundancy and reliability at a minimum energy consumption cost. To satisfy these conflicting constraints, wireless sensor networks (WSN) routing protocols generally employ a clustering algorithm in which the entire network does not have to be active at all times. In this paper, we propose a novel...
With the success of wireless technologies in consumer electronics, standard wireless technologies are envisioned to be deployed in industrial environments as well. Many industrial applications have stringent requirements on reliability and timing. In wired environments, reliability is well catered by field-bus systems. When wireless links are adopted, reliability requirement is significantly more...
WSN's reliability plays an extraordinary role in certain applications. Among the reliability related solutions, the reliability of the network largely dependent on the routing reliability which mainly dependents on both aspects of the cluster-heads' reliability and gateways' reliability. This paper proposes a novel redundancy-based directional reliable multi-hop clustering routing algorithm (DRMC)...
Body sensor networks are an interesting emerging application of wireless sensor networks to improve healthcare and the quality of life. Current research has mainly focused on single-hop networks, although some works clearly show advantages of multi-hop architectures. In this paper, we model probabilistic connectivity in such multi-hop body sensor networks. Instead of using a circular coverage area,...
This paper presents a reliable routing protocol for wireless ad hoc and sensor networks which is based on the DSR routing protocol. The protocol achieves increased reliability through the maintenance of a reliability factor by the nodes in the network. During the route discovery process, the request messages are only propagated to nodes with a reliability factor that is above a threshold value specified...
