In-Network Phased Filtering Mechanism for a Large-Scale RFID Inventory Application

چکیده
-RFID technology is one of automatic identification technologies. In current RFID systems, RFID data are managed and processed by a middleware. In the near future, when RFID technology will be applied to large scale warehouses, airports, or seaports, it is necessary that wireless sensors integrated a RFID reader construct wireless sensor network because of difficulties of building wired network infrastructure. However adjacent RFID readers in wireless sensor network can generate many duplicate data at the same time. These duplicate data transmissions may waste the energy of sensor nodes integrated a RFID reader and cause network congestions. So we propose in-network phased filtering mechanism for a large-scale RFID inventory application. In this paper, we describe our idea to reduce a processing time of filtering and confirm the idea by a simulation.

A conic quadratic model for supply chain network design under hub, capacity, delay and lost sale
In this paper, mathematical models are proposed for simultaneously modeling location and inventory control decisions in a four echelon supply chain network considering capacity. The echelons considered in this paper include suppliers, warehouses, hubs and retailers. The aim of the model is to minimize the location, transportation and inventory control costs. Hence, a non-linear mixed integer pr...

State estimation is the foundation of any control and decision making in power networks. The first requirement for a secure network is a precise and safe state estimator in order to make decisions based on accurate knowledge of the network status. This paper introduces a new estimator which is able to detect bad data with few calculations without need for repetitions and estimation residual cal...

Nowadays, Network Intrusion Detection Systems (NIDS) are widely used to provide full security on computer networks. IDS are categorized into two primary types, including signature-based systems and anomaly-based systems. The former is more commonly used than the latter due to its lower error rate. The core of a signature-based IDS is the pattern matching. This process is inherently a computatio...
