This article proposes two new mechanisms to allow a fair power consumption in mobile ad-hoc networks using the OLSR routing protocol. The key element of OLSR is the election of special nodes called MPR nodes which are designed to broadcast control packets. We propose to introduce new MPR selection criteria which take into account the energy capacity of(More)
Radio Frequency Identification (RFID) technology is a method to remotely store and retrieve data using a small microchip called the RFID tag. This makes identification, authentication of objects and people possible without any physical contact between a tag and its reader. First developed in 1940 by the British army, RFID have developed considerably thanks(More)
Radio Frequency Identification (RFID) technology is a method to remotely store and retrieve data using a small microchip called the RFID tag. This makes identification, authentication of objects and people possible without any physical contact between a tag and its reader. As of today, RFID have been applied to a wide range of problems: supply chain(More)
Mobility models are used in the network simulation area to reproduce the typical behaviour of nodes. If lots of mobility models have been proposed in the literature, very few are taking into account the social behaviour of users. In this paper, we propose a modelling framework to introduce social behaviours into existing mobility models so as to evaluate(More)
Mobile devices are carried by people, which are characterized by their need to socialize. The social character of mobile networks may have an influence in modeling the mobility of their nodes, and consequently in the performance evaluation of the network. In this paper, we introduce social behaviors into existing mobility models so as to mimic real motion(More)
Position-based routing protocols take advantage of location information to perform a stateless and efficient routing. To enable position-based routing, a node must be able to discover the location of the messages’ destination node. This task is typically accomplished by a location service. Recently, several location service protocols have been developed for(More)
Due to advances in silicon manufacturing technology, Radio Frequency Identification (RFID) systems are useful in many applications such as automobile immobilizers, animal tracking, payment systems, automatic toll collection and inventory management. As RFID systems use both radio and wire communication, security issues become a critical concern. However,(More)
