The node localization problem in mobile sensor networks has received significant attention. Recently, particle filters adapted from robotics have produced good localization accuracies in conventional settings. In spite of these successes, state-of-the-art solutions suffer significantly when used in challenging indoor and mobile environments characterized by a high degree of radio signal irregularity...
The effect of advances in the fields of ubiquitous computing, wireless communications and embedded system design has seen a corresponding rapid improvement of wireless sensor technology. Sensor networks have emerged as a platform for deployment and sustenance of critical applications that require real-time sensing and data acquisition for decision-making purposes. A significant number of malicious...
Recent advances in the field of wireless networks have entailed collateral growth in the number of possible malicious attacks against them. A significant amount of work has been done towards ensuring security of a class of such networks, namely, Wireless Sensor Networks. Considering the untrusted environments of operations of such networks, the threat of distributed attacks against constrained resources...
Data aggregation is a crucial technique for energy constrained sensor networks. Previous researches on data aggregation are featured as query-oriented, which only provide partial information of the event happened in the deployment area at the base station. In this paper, we propose an event-oriented data aggregation approach, called EDA. EDA presents the distributed algorithm by exploiting Cloud Membership...
We target an interesting problem of simultaneous optimization of lifetime and source-to-sink delay in wireless sensor networks, and present a fuzzy multiobjective online routing algorithm. For a routing request, the proposed routing algorithm finds a path that offers a good balance between the two routing objectives, namely maximizing the network lifetime and minimizing the source-to-sink delay. Fuzzy...
We address the maximum lifetime routing problem in wireless sensor networks, and present an online multipath routing algorithm. The proposed algorithm strives to maximize the network lifetime metric by distributing the source-to-sink traffic for a given routing request along a set of paths. Fuzzy membership function is used for designing the edge weight function. Simulation results obtained under...
We address the maximum lifetime routing problem in wireless sensor networks (WSNs) and propose two online routing algorithms based on fuzzy logic, namely fuzzy maximum lifetime algorithm and fuzzy multiobjective algorithm. The former attempts to maximize the WSN lifetime objective, whereas the latter strives to simultaneously optimize the lifetime as well as the energy consumption objectives. The...
In our latest work, we developed a data fusion algorithm which can be applied on fusion centers of a cluster-based wireless sensor network (WSN). The data fusion algorithm is a mathematical model based on fuzzy logic theory. In fuzzy logic, a collection of objects is processed using fuzzy sets to obtain a value, which summarizes the collection. In this paper, we examine the effects of imprecise WSN...
