Abstract

Abstract –Wireless sensor networks undergo tremendous applications to be utilized for. In this paper, we propose a wireless ad hoc sensor network architecture that does not depend on a centralized unit to urban city’s vehicular control, by applying different sensors distribution for main and side streets. On this architecture, we define and evaluate through simulation the effectiveness of our work against the traditional fixed-time traffic light model. Traffic lights coordination is addressed in master and local controllers by executing green-wave algorithm at our architecture. Simulation results show that this architecture achieves great reduction in total waiting time on the city been projected

Abstract

Vehicular network security had spanned and covered a wide range of security related issues. Howeversolar energy harvesting Road Side Unit (RSU) security was not defined clearly, it is this aspect that is considered in this paper. In this work, we will suggest an RSU security model to protect it against different internal and external threats. The main goal is to protect RSU specific data (needed for its operation) as well as its functionality and accessibility. The suggested RSU security model must responds to many objectives, it should ensure that the administrative information exchanged is correct and undiscoverable (information authenticity and privacy), the source (e.g., VANET server) is who he claims to be (message integrity and source authentication) and the system is robust and available (using Intrusion Detection System (IDS)). In this paper, we suggest many techniques to strength RSU security and they were prototyped using an experimental model based on Ubicom IP2022 network processor development kit .
