    Abstract
    Reliability and energy consumption are two of the main constraints in wireless sensor networks (WSNs). In this paper, a novel energy efficient and high speed error control scheme is introduced that is based on the Redundant Residue Number System (RRNS) allowing real-time application of WSNs. The proposed approach employs a new 3-moduli set {22n+1, 2 2n1-1, 2n- 1 } and an efficient reverse converter which relies on the Mixed Radix Conversion (MRC) algorithm and achieves significant improvements both in terms of conversion delay and hardware design. In order to obtain error controllability, two-redundant-moduli set 23n+1 - 1, 24n+1 - 1 is also added to the main 3-moduli set. The theoretical... 

    RDTP: reliable data transport protocol in wireless sensor networks

    Abstract
    The paper deals with a new reliable data transport protocol for wireless sensor networks, referred as RDTP. One of the most prominent challenges in wireless sensor networks is reliable transport of data from sensor nodes to sink node. For designing protocols for such networks hardware, some constraining factors associated with energy and processing power must be taken into consideration. There are two generic methods, ARQ and FEC to achieve reliable data transport. Here, a reliable data transport protocol for wireless sensor networks is proposed, in which an efficient moduli set in redundant residue number system has been employed. The modulus set is exploited as a means for adding... 

    A Framework for the Definition, Elaboration and Optimization of Service levels in Cloud Manufacturing Network, Considering Service Composition in the Transportation and Logistics

    Abstract
    Regarding to emergence of the globalization concepts in manufacturing, technology and information technology has come to aid of the organizations to expand communication across the globe, in order that companies can overcome many of their deficiencies in this way. To achieve this goal, Cloud Manufacturing (CMfg) system have been investigated, while today the CMfg is a new manufacturing paradigm and is one of the dominant concepts in manufacturing industries. Regarding to the nature of the cloud, the resources used to meet the customer demands are not necessarily concentrated in a specific geographic location, or the demand of a customer may not be satisfied with a distinct service, as a...
