Peer-to-Peer framework for RFID/non-RFID reader-enabled users
Radio Frequency Identification (RFID) technology can be used for a wide range of applications such as tracking and tracing objects and individuals, localization, collaborative platforms and the like. For portable devices with non-RFID capabilities there is no possibility to allow them to benefit from this technology if no integration platforms are implemented. In this paper we propose an architectural framework in order to enable RFID applications for devices that have non-RFID reading capabilities but a wireless interface. We also propose an application layer time-division-based scheme to allow RFID-enabled devices to scan for RFID tags, preventing reader-to-reader interference and avoiding reading collisions. We depict the system architecture and we perform simulations to compare transmission delay metrics and numerical results are provided.

Platform and experimentation of secure service location with P2P/Client-Server over ad hoc networks
Ad hoc networking is considered as an inexpensive solution for easy and fast wireless network coverage. However, for real service deployment, security and availability in such networks are still under research even though some experimentation has shown its viability. We propose to offer a secure location of services in an ad hoc environment. We focused on the development of a proxy-based solution to combine a P2P-client/server network overlay in order to provide securely the location information of network services and to set a platform that can include application services. A detailed description of the system architecture and platform is provided describing all the modular components as well as numerical results derived from a simple test bed.

RFID network topology design based on Genetic Algorithms
Radio Frequency Identification (RFID) is a well known technology that has entered successfully in the realm of innumerable applications and is considered as one of the principal building blocks for the realization of the Internet of Things concept. However, the majority of RFID applications require the utilization of multiple RFID readers and therefore effective and efficient planning of their networks is a major concern. Network planning is a complex process that involves different steps, one of which is its topology design. In this paper, we focus on the topology design process of a RFID network following an optimization-based approach. More precisely, we propose a multi-objective cost function that is used to evaluate candidate solutions for the position and power levels of the set of RFID readers to be deployed. In order to obtain optimal solutions we applied Genetic Algorithms, a well known heuristic technique. Finally, a developed software tool to assist in the topology design is also presented and processing delay measurements are performed.

RFID service for non-RFID enabled devices: Embedded hardware implementation
Radio Frequency Identification (RFID) applications require the use of specialized hardware in order to obtain the IDs that are provided by the tags. This condition limits the extension of the information to devices with non-RFID capabilities. In this paper we present the design and implementation of a RFID service conceived for devices with non-RFID hardware but a WLAN interface. More specifically, we utilized embedded hardware to build an affordable and practical device that allows obtaining lists of tag IDs by using a common WLAN interface. Additionally, we performed delay metrics experiments and measurements are provided.
