In this article, the SAR (Security-Aware Routing) technology is applied in the AODV (Ad Hoc On-demand Distance Vector) routing protocol, the AODV is modified as viewed from security performances, the wireless Ad Hoc routing protocol with secure consciousness could be realized, and the secure routing protocol (SAR-AODV) is simulated in the OMNet++ simulation environment based on the platform of ...

With the spread of connected vehicles (CVs), a growth novel information services exploiting data transmitted by CVs is expected. Wireless communication systems, in particular vehicular applications, operate with varying level transmission reliability, which may affect quality V2X-data-driven intelligent transport systems (ITS). Therefore, performance ITS should be evaluated variety conditions a...

The Internet of Things (IoT) utilizes trillions of uniquely identifiable smart objects to connect anything at anytime and anywhere. Radio frequency identification (RFID) techniques are a powerful promising enabler for realizing the IoT. Around how to build hierarchical networked RFID systems for the IoT, this dissertation formulates and addresses problems in three key areas, i.e., communication...

This paper describes the implementation of an OMNeT++-based HiperLAN/2 simulation model. The simulation models the HiperLAN/2 standard with a large degree of accuracy, in particular, in the DLC layer. It is designed to be extendable and flexible and incorporates HiperLAN/2 protocol extensions for multihop relaying. It is publicly available.

This work describes our implementation of a framework that allows mobile nodes in OMNeT++ simulations to be equipped with multiple radio subsystems that can be dynamically suspended and woken up. Our framework enables the simulation of wireless architectures that exploit radio hierarchies for power-efficient neighbor and service discovery and connection setup. The design is implemented as an ex...

Simulation involves using a model to produce results, rather than experimenting with a real system. Simulations are typically computationally intensive problems, and lend themselves for execution on large-scale PC clusters or grids. Use of grid infrastructure for discrete event simulation like communications network simulations, or queuing network simulations etc. is not prevalent; making grid ...

The use of peer-to-peer overlay networks (P2P) to deliver live television on the Internet (P2P TV) is gaining increasing attention. P2P TV systems are growing nowadays at increasing speed as a result of the opening of video content producers to new business models. This process is supported and accelerated by larger bandwidth availability of Internet and better algorithms for compression, repro...
