“…The observed parameters include efficient utilization of communication bandwidth within the clusters, avoiding redundant message transfer between the nodes, localizing energy efficient route setup within the clusters, reduction in energy consumption, etc. [1], [2] made an analysis that reliable routing of packets from nodes to its base station is the most important task for the networks. Routing in wireless networks is bit more complex than other wired networks.…”

“…Clustering produces initial categories in which values of a data set are further classified during the classification process. Previous works [1,2] have tried to develop intelligent receivers that are capable of identifying the incoming modulation scheme and reconfigure themselves accordingly. However, these architectures support only a very limited number of constellations, thus limiting both generality and performance [13][14][15].…”

A technique for grouping different modulation schemes in a nodal management network (by clustering identically modulated nodes) is presented in this paper. The modulation tracking scheme localizes a specific node (allocated with a unique, but dynamically varying modulation scheme). The clustering mechanism to group the identical nodes exists intrinsically. The proposed modulation identification scheme and clustering mechanism are implemented using high speed architectures and the performance of the proposed approach is validated for multiple modulation scenarios.

“…While these provide insight into securing virtual coordinate systems, the majority of the solutions rely on assumptions that are not applicable in the P2P domain. Defense mechanisms such as SPINE [Capkun and Hubaux 2005], LAD [Du et al 2006], and TCSD [Chen et al 2008] as well as those proposed by and Mathews et al [2007] rely heavily on a pre-defined set of reference nodes to identify potentially malicious activity. ROPE , SLA [Anjum et al 2005], and the work by Mathews et al [2007] require the reference nodes to be trusted.…”

Virtual coordinate systems provide an accurate and efficient service that allows hosts on the Internet to determine the latency to arbitrary hosts without actively monitoring all of the nodes in the network. Many of the proposed systems were designed with the assumption that all of the nodes are altruistic. However, this assumption may be violated by compromised nodes acting maliciously to degrade the accuracy of the coordinate system. As numerous peer-to-peer applications come to rely on virtual coordinate systems to achieve good performance, it is critical to address the security of such systems.In this work, we demonstrate the vulnerability of decentralized virtual coordinate systems to insider (or Byzantine) attacks. We propose techniques to make the coordinate assignment robust to malicious attackers without increasing the communication cost. We use both spatial and temporal correlations to perform context-sensitive outlier analysis to reject malicious updates and prevent unnecessary and erroneous adaptations. We demonstrate the attacks and mitigation techniques in the context of a well-known virtual coordinate system using simulations based on three representative, real-life Internet topologies of hosts and corresponding round trip times (RTT). We show the effects of the attacks and the utility of the mitigation techniques on the virtual coordinate system as seen by higher-level applications, elucidating the utility of deploying robust virtual coordinate systems as network services.

“…We assume that a compromised node is eventually detected: different detection strategies exist in literature [14,15]. If a node is compromised, the ACM increments c 1 and c 2 , and transfers to all non-compromised sensors, on a secure channel, the updated value S = h(S, c 1 ): this step can be performed through a secure broadcast scheme 4 .…”

“…This is a common assumption, and it represents an active area of research (for instance see [14,15]). Last, we assume that there is a way to distribute key updates secretly and on an authenticated channel, and there is a way to distribute authenticated messages commanding nodes to update their counters.…”

Abstract. Although very developed in many sectors (databases, filesystems), access control schemes are still somewhat elusive when it comes to wireless sensor networks. However, it is clear that many WSN systems -such as healthcare and automotive ones -need a controlled access to data that sensor nodes produce, given its high sensitivity. Enforcing access control in wireless sensor networks is a particularly difficult task due to the limited computational capacity of wireless sensor nodes. In this paper we present a full-fledged access control scheme for wireless sensor data. We enforce access control through data encryption, thus embedding access control in sensor data units. We also propose a lightweight key generation mechanism, based on cryptographic hash functions, that allows for hierarchical key derivation. The suggested protocol only relies on simple operations, does not require interactions between nodes and data consumers and has minimal storage requirements.
