An attempt to realize advantages with a minimum...
Smart grids (SG) are essential for efficient management and monitoring of electric power networks. One of the most important tasks in SG focuses on fault detection and automatic network reconfiguration. This process allows minimizing power losses and load balancing in distribution networks. In this paper, an adaptation of the open shortest path first (OSPF) routing protocol to accomplish the network...
Internet of Things (IoT) is becoming a reality and new and advanced applications are expected to emerge. For applications with reliability needs to work well in IoT environments, robust data transportation is required. Approaches like TCP are known for not being adequate in sensor network environments, while UDP has been included in the 6LoWPAN stack allowing low-power and limited processing devices...
Wireless sensor networks (WSNs) are widely applied in various industrial applications. In this paper, we present an efficient data gathering scheme that guarantees the Quality of Service and optimizes the following network performance metrics as well as the end-to-end reliability in WSNs: 1) minimum total energy consumption; 2) minimum unit data transmitting energy consumption; and 3) maximum utilization...
Wireless sensor networks have a wide range of applications including target detection and tracking, environment monitoring, industrial process monitoring, hospital monitoring, and public utility service. A sensor network consists of a large number of sensor nodes and a few sink nodes to collect data from sensor nodes. Sensor nodes and sink nodes form a large scale wireless mesh network in which packets...

In this paper, we study the reliable packet forwarding in Wireless Sensor Networks (WSNs) with the multiple-input multiple-output (MIMO) and orthogonal space time block codes (OSTBC) techniques. The objective is to propose a cross-layer optimized forwarding scheme to maximize the Successful Transmission Rate (STR) while satisfying the given end-to-end energy consumption constraint. The channel coding,...
In this paper a Rayleigh fading model based reliability-centric routing algorithm is proposed for Wireless Sensor Networks (WSNs). The proposed scheme is optimized with respect to minimal power consumption to improve longevity as well as to ensure reliable packet transmission to the Base Station (BS). Reliability is guaranteed by selecting path over which the probability of correct packet reception...
Aiming at reliable data delivery in wireless sensor networks, virtual multipath routing (VMR) protocol is proposed. The defining aspect it differs from the traditional ones is it integrates path quality probing, data transmission and route optimization together. In this protocol, multiple paths are engaged in data delivery; meanwhile accumulated transmission times (ATT) of each packet from source...
