    The significant advances of hardware manufacturing technology and the development of efficient software algorithms make technically and economically feasible a network composed of numerous, small, low-cost sensors using wireless communications, that is, a wireless sensor network. WSNs have attracted intensive interest from both academia and industry due to their wide application in civil and military scenarios. In hostile scenarios, it is very important to protect WSNs from malicious attacks. Due to various resource limitations and the salient features of a wireless sensor network, the security design for such networks is significantly challenging. In this article, we present a comprehensive survey of WSN security issues that were investigated by researchers in recent years and that shed light on future directions for WSN security.

    This article surveys research in service advertising, discovery, and selection for mobile ad hoc networks and related issues. We include a categorization of service discovery architectures for MANETs and their modes of operation, presenting their merits and drawbacks. We pay particular attention to cross-layer service discovery - a special class of efficient service discovery approaches for MANETs. We also present security issues and discuss service description options, service selection mechanisms, and service-state maintenance techniques. We conclude with a summary, an outlook, and directions for future research in this area. View full abstract»

    We compile and classify the research work conducted for Ethernet passive optical networks. We examine PON architectures and dynamic bandwidth allocation algorithms. Our classifications provide meaningful and insightful presentations of the prior work on EPONs. The main branches of our classification of DBA are: grant sizing, grant scheduling, and optical network unit queue scheduling. We further examine the topics of QoS support, as well as fair bandwidth allocation. The presentation allows those interested in advancing EPON research to quickly understand what already was investigated and what requires further investigation. We summarize results where possible and explicitly point to future avenues of research. View full abstract»

  • A design framework and taxonomy for hybrid routing protocols in mobile Ad Hoc networks

    Routing protocols for mobile ad hoc networks can be classified into two categories: topological routing and geographic routing. Hybrid routing protocols that take advantage of both schemes have attracted a lot of attention recently. This article provides a systematic survey of these hybrid routing protocols. We first analyze the three types of routing information used in the hybrid routing protocols, namely, topological information, geographic information, and hierarchy information. Then, based on a review of the representative hybrid routing protocols, we summarize the three design options for hybrid routing protocols, namely, radius of the routing zone (1, k, or D), geographic information (position or position plus partition), and routing structure (flat or hierarchical). Finally, we propose a three-dimensional design framework that can accommodate well all of the existing hybrid routing protocols. The framework also helps find the unexplored design space, motivating the design of new hybrid routing protocols. View full abstract»

    This article presents a comprehensive survey of the state-of-the-art for vehicle ad hoc networks. We start by reviewing the possible applications that can be used in VANETs, namely, safety and user applications, and by identifying their requirements. Then, we classify the solutions proposed in the literature according to their location in the open system interconnection reference model and their relationship to safety or user applications. We analyze their advantages and shortcomings and provide our suggestions for a better approach. We also describe the different methods used to simulate and evaluate the proposed solutions. Finally, we conclude with suggestions for a general architecture that can form the basis for a practical VANET. View full abstract»
