    Materiality Analysis for CSR Reporting in Spanish SMEs

    Most Corporate Social Responsibility (CSR) standards have not been designed to be implemented in Small and Medium sized Enterprises (SMEs). Given that 99% of Spanish companies are SMEs, this study aims to propose a selection of basic CSR material issues that, because of their usefulness and significance, should be adapted...

    Global SMEs' Strategy

    In developed countries the number of SMEs vastly exceeds the number of MNCs. An important share of SMEs are somehow linked to MNCs - but the impression prevails, that SMEs are in a subordinate position and certainly do not have a global strategy. The authors argue, however, that there should...

    Capacity of Interference-Limited Three Dimensional CSMA Networks

    Wireless multi-hop networks have been increasingly used in military and civilian applications. In many a applications, the region in which the network is deployed is better modeled by a 3D space, instead of a Two Dimensional (2D) planar area. Examples include a wireless network deployed across different floors inside a...

    Uncoordinated Cooperative Truncated ARQ Schemes in Wireless Systems

    In this paper, the authors propose two uncoordinated cooperative truncated ARQ schemes based on node position or local SNR information. If the original transmission between a source and a destination fails, the source and all the potential relays that have correctly received the data packet will contend for the channel...

    On the Information Propagation Process in Multi-Lane Vehicular Ad-Hoc Networks

    This paper studies the information propagation process in a 1D mobile ad-hoc network formed by vehicles traveling on a highway. The authors consider that vehicles can be divided into traffic streams; vehicles in the same traffic stream have the same speed distribution, while the speed distributions of vehicles in different...

    On Graphs Supporting Greedy Forwarding for Directional Wireless Networks

    Greedy forwarding is an efficient and scalable geographic routing algorithm for wireless networks. To guarantee the success of greedy forwarding, many research efforts assign virtual coordinates to nodes to obtain a greedy embedding of the network. Different from these existing efforts, this paper presents an approach that enables greedy forwarding...

    How a Consumer Can Measure Elasticity for Cloud Platforms

    One major benefit claimed for cloud computing is elasticity: the cost to a consumer of computation can grow or shrink with the work-load. This paper offers improved ways to quantify the elasticity concept, using data available to the consumer. The authors define a measure that reflects the financial penalty to...

    A Traffic Density Model for Radio Overlapping in Urban Vehicular Ad Hoc Networks

    Vehicular traffic density is a key factor in determining the behavior of radio overlapping and thus impacts performance of data and safety message communication in Vehicular Ad hoc Networks (VANETs). In this paper, the authors propose a novel density model for urban traffic systems and employ this model for the...

    Analytical Bounds on the Critical Density for Percolation in Wireless Multi-Hop Networks

    In a wireless multi-hop network there are a number of self-organized and decentralized wireless nodes which communicate with each other in a peer-to-peer manner over wireless channels. Each node helps in forwarding packets from source nodes to destination nodes in a multi-hop manner. In such a network, one node must...

    Reducing Transmission Losses in Body Area Networks Using Variable TDMA Scheduling

    The authors consider a typical Body Area Network (BAN) setting in which sensor nodes send data to a common hub regularly on a TDMA basis, as defined by the emerging IEEE 802.15.6 BAN standard. They explore variable TDMA scheduling techniques that allow the order of transmissions within each TDMA round...

    What Do Managers' Survey Responses Mean And What Affects Them? The Case Of Market Orientation And Firm Performance

    Using cross-sectional surveys to support proposals of causal sequences in theoretical models is problematic, especially when the surveys are of managers and performance is a dependent variable. The results of such surveys reveal more about managers' sensemaking processes than the actual processes, a rival causal theory that marketing potentially ignores....

    Use of Flip Ambiguity Probabilities in Robust Sensor Network Localization

    Collinear or near collinear placement of some sensors in a wireless sensor network causes the location estimates of nearby sensors to be sensitive to erroneous distance measurements which leads to large location estimation errors. These errors and the possible propagation of these errors to the entire network or a large...

    Evaluation of Three Vision Based Object Perception Methods for a Mobile Robot

    This paper addresses object perception applied to mobile robotics. Being able to perceive semantically meaningful objects in unstructured environments is a key capability in order to make robots suitable to per-form high-level tasks in home environments. However, finding a solution for this task is daunting: it requires the ability to...

    Connectivity of Wireless CSMA Multi-Hop Networks

    In this paper, the authors consider the impact of interference on the connectivity of CSMA networks. First, it is shown that the aggregate interference experienced by any receiver in a CSMA network with arbitrarily distributed nodes is upper bounded. Then, they derive an equivalent transmission range for CSMA networks where...

    Two-Step and Apex-Angle Routing Algorithms for Delaunay Triangulations

    Memoryless Online Routing (MOR) algorithms are suitable for the applications only using local information to discover paths, and Delaunay triangulations are the class of geometric graphs widely proposed as wireless network topologies. Motivated by these two facts, this paper reports two new MOR algorithms for the Delaunay triangulations: the Two-step...

    VLOCI: Using Distance Measurements to Improve the Accuracy of Location Coordinates in GPS-Equipped VANETs

    Many vehicles rely on the Global Positioning System (GPS) to compute their locations. The inaccuracy of GPS devices means sometimes vehicles believe they are located in different lanes or roads altogether. Vehicular Ad hoc NETworks (VANETs) allow vehicles to communicate with each other using wireless means and thus connect them...
