In this paper, we propose to leverage high-speed rail as mobile actor to assist structural health monitoring (SHM) data collection and delivery for wireless sensor and actor networks (WSANs). Due to high density in the network topology, sensor observations have spatial and temporal correlation. With the spatiotemporal correlation, we first provide a two-phase data collection scheme. In the first phase, the WSANs transmit the data to a sink node and then aggregate the data using the spatial correlation. In the second phase, when the high-speed train passing by the tunnel or the bridge, the sink node transmits the data to the train and then aggregate the data with consideration of the temporal correlation. Also because of the high speed mobility of the train, the communication link between the sink and the train may be fail, so we need to estimate the lost packet. We then estimate spatiotemporal distortion to denote the event collection's reliability/fidelity. Through extensive simulation, we discuss several key elements that will affect the reliability.

Recently, wireless sensor and actor networks (WSANs) technology has been also applied for monitoring critical infrastructure protection (CIP). These new applications make more demanding requirements of WSANs and therefore it is necessary to develop algorithms that can manage the communications and route the information from each sensor node to the sink nodes while providing quality-of-service (QoS) requirements. In order to assess the current state of WSANs in terms of performance and QoS support, this article empirically studies the performance of a network with different workloads in terms of reliability, delay and queue occupation with common network topologies. The results reveal the intrinsic lack of reliability and low throughput that this technology currently exhibits, the importance of matching network level capabilities to data link layer capabilities and different behaviour of a PQS in terms of reliability and delay depending on the congestion of the network.

The challenge of efficient point-to-point communication in meshed wireless sensor and Actuator networks (WSANs) can be addressed by Software Defined Networking (SDN). In contrast to the traditional routing protocols for wireless sensor networks (WSNs) that use distributed local information for routing decisions, SDN based routing protocols can access global topology information for routing decisions. The global topology information enables more efficient routing decisions. Accordingly, this paper proposes the SDN based innovative Dynamic Traffic Aware Routing Protocol (DTARP) that uses up-to-date traffic information from the WSAN and topology metrics from graph theory to increase the overall energy efficiency of the WSAN and to avoid traffic congestion in the network. The proposed routing algorithm has been prototyped and compared to other routing algorithms. The evaluation shows a clear advantage of SDN-based routing for peer-to-peer IoT communication.

On "Movement-Assisted Connectivity Restoration in wireless sensor and actor networks"

In wireless sensor and actor networks (WSANs), a set of static sensor nodes and a set of ( mobile) actor nodes form a network that performs distributed sensing and actuation tasks. In [1], Abbasi et al. presented DARA, a Distributed actor Recovery Algorithm, which restores the connectivity of the interactor network by efficiently relocating some mobile actors when failure of an actor happens. To restore 1 and 2-connectivity of the network, two algorithms are developed in [1]. Their basic idea is to find the smallest set of actors that needs to be repositioned to restore the required level of connectivity, with the objective to minimize the movement overhead of relocation. Here, we show that the algorithms proposed in [1] will not work smoothly in all scenarios as claimed and give counterexamples for some algorithms and theorems proposed in [1]. We then present a general actor relocation problem and propose methods that will work correctly for several subsets of the problems. Specifically, our method does result in an optimum movement strategy with minimum movement overhead for the problems studied in [1].

Event Ordering by Double Confirmation in wireless sensor and actor networks

IEEE sensorS JOURNAL 2011年第3期11卷 829-836页

wireless sensor and actor network (WSAN) is a new kind of heterogeneous wireless sensor networks. In WSANs, while sensors gather and send the sensing messages from the physical environment, actors need to take appropriate actions. Based upon the rich source actor, WSANs are increasingly deployed for accurately monitoring the environments subjected to critical conditions. The ordering of monitored events actor received could determine the correct interpretation of what event is occurring in the monitored environment. Hence, event ordering in WSAN is an important issue for applications in monitoring. To address this issue, we proposed an event ordering by double confirmation (OBDC) that could guarantee the event ordering to be correct completely. The simulation results demonstrated that the rate of correct event ordering of OBDC could be up to 100%, but its event handling time and energy consumption increased only more 3.2% and 4.4%, respectively, than the existing algorithm, OBC. However, OBDC still assures the rate of correct event ordering to be 100%, as the quantity of sensed events increased.

wireless sensor and actor networks (WSANs) are likely to become a pervasive technology in the near future due to the special characteristics of these devices and to the great number of applications where it can be applied. One of these applications is the critical infrastructure protection (CIP). In fact, WSANs have actually been identified as having the potential to become an integral part of the CIP. However, in order to achieve that goal, WSANs need to provide a set of features which includes a robust QoS. Unfortunately QoS support mechanisms in WSANs are still largely undeveloped. This paper studies the state-of-the-art of QoS management in WSANs by exploring existing proposals, challenges and open issues in the field. Emphasis is put on QoS in the context of CIP by focusing on the QoS requirements and the needs of CIP applications. Existing middleware and protocols are surveyed and the challenges and open issues in the field are presented. (C) 2011 Elsevier Ltd. All rights reserved.

wireless sensor and actor networks (WSANs) have received increased attention from the research community in the recent years. This is mainly because as an extension to wireless sensor networks(WSN), they have the ability to actively participate in the environment trough the actors. However, this introduces new challenges as to how to transfer commands between nodes, actors and central station who may be from different manufacturers and use different communication protocols. Another important aspect is the ability of the WSAN to present the data to the interested party or to receive the command from the operator, and do this with in the simplest and most user friendly way as possible. In this paper we propose architecture for interconnection between different layers of WSANs and the central stations that would allow building a simple interface that would ease the operation with WSANs in view of Control and Data Acquisition.

In most applications of wireless sensor and actor network it is important to sustain connectivity among all actors at all times. When an actor fails the inter-actor topology may get partitions into disjoint blocks and the application may be negatively impacted. Tolerating the actor failure and restoring the lost connectivity need to be performed while imposing the least overhead on the individual actors. In this paper a Least Distance Movement Recovery (LDMR) algorithm is proposed. LDMR is a distributed approach that exploits non cut-vertices actors in the recovery process. The idea is for a set of direct neighbours of the failed node to move toward the position of the failed node while its original position is replaced with the nearest non cut-vertex actor. The recovery process starts with the search phase where each neighbour broadcasts a message containing the failed node ID, neighbour node ID and, Time-To-Live (TTL). When a neighbour receives responses, it chooses the best candidate based on a certain criteria (e.g. distance). We compare our approach with Recovery through Inward Motion (RIM) which depends only on cascaded movements. Extensive simulation experiments are carried out to validate the performance.

We propose a localized Delay-bounded and Energy-efficient Data Aggregation scheme (DEDA) for wireless sensor and actor networks that are modeled as undirected graphs (URG). The scheme is based on a novel concept of Desired Hop Progress (DHP) and designed for low-traffic, request-driven network scenarios, where delay is proportional to hop count [10]. It builds a local minimal spanning tree (LMST) sub-graph of the network with links weighted by transmission powers. Using edges from LMST, it constructs a shortest path (thus energy-efficient) tree rooted at actor (sink) for data aggregation. The tree is used as is if it generates acceptable delay. Otherwise, it is adjusted by replacing LMST sub-paths with URG edges. The adjustment is done locally, according to the DHP value at each node, with hop count reduction corresponding to the delay allowance per hop (ratio of current LMST delay over maximal allowed one). Through extensive simulation, we show that DEDA may save 25-75% energy per node on average and extend up to 150% network life, depending on network conditions, in comparison with the only existing competing localized solution [11].
