With sensor networks on the verge of deployment, security issues pertaining to the sensor networks are in the limelight. Though the security in sensor networks share many characteristics with wireless ad hoc networks, the two fields are rapidly diverging due to the fundamental differences between the make‐up and goals of the two types of networks. Perhaps the greatest dividing difference is the energy and computational abilities. Sensor nodes are typically smaller, less powerful, and more prone to failure than nodes in an ad hoc network. These differences indicate that protocols that are valid in the context of ad‐hoc networks may not be directly applicable for sensor networks. In this paper, we survey the state of art in securing wireless sensor networks. We review several protocols that provide security in sensor networks, with an emphasis on authentication, key management and distribution, secure routing, and methods for intrusion detection.

In this paper, we propose a formal study based on model checking to formally verify an enhancement authenticated version of ad hoc on‐demand multipath distance vector (AOMDV) called authenticated optimized AOMDV (AO‐AOMDV). In this new version, we have added new functionalities in route discovery and route maintenance processes combined with the advantages of μTESLA. This contribution allows a transmitter to compute multiple authenticated routing paths toward the destination. The result of the formal verification study, under UPPAAL and SPIN, shows the behavior of the protocol that may not be revealed by simulation. 相似文献

Time‐division multiple‐access (TDMA) is a common medium access control paradigm in wireless sensor networks. However, in its traditional form, the TDMA‐based protocols suffer from low channel utilization and high message delay because of a long frame length needed to provide collision‐free transmissions, which is particularly damaging in dense wireless sensor networks. In this paper, we investigate the performance and the energy efficiency of a class of TDMA‐based protocols, called reduced‐frame TDMA, where every TDMA slot is augmented with a short time period dedicated for carrier sense multiple access‐based contention resolution mechanism. Because of their ability to dynamically resolve collisions caused by conflicting slot assignments, the reduced‐frame TDMA protocols can be configured with any frame length, independently of node density. In addition, we present a distributed heuristic slot assignment algorithm that minimizes interslot interference in the presence of limited number of slots per frame. The simulation results indicate that the reduced‐frame TDMA protocols significantly reduce the message delay and increase the maximum throughput without incurring significant penalty in energy efficiency compared with the traditional TDMA scheme.

With the rapid advancement in the Internet of things, protocols are challenged to perform routing with low power over lossy networks (RPLs). Performance analysis of RPL attracted many researchers in the field. However, to the best of our knowledge, limited or no studies have been made to develop heterogeneous analytical models that aim at the classification and ranking of RPL deployments based on combinations of desired properties. In this paper, we develop an analytical framework that captures the effectiveness of RPL and enables its sound evaluation and classification. Performance metrics include power consumption, churn in, received packets, and duty cycle, to name but a few. The obtained results based on our analytical framework confirms its effectiveness compared to the simulation results obtained in the literature. The best performance is noted for the deployments with 50 m of range and for different number of nodes. 相似文献
