Cost-Aware SEcure Routing (CASER) Protocol Design for Wireless Sensor Networks

Lifetime optimization and security are two conflicting design issues for multi-hop wireless sensor networks (WSNs) with non-replenishable energy resources. In this paper, we first propose a novel secure and efficient Cost-Aware SEcure Routing (CASER) protocol to address these two conflicting issues through two adjustable parameters: energy balance control (EBC) and probabilistic-based random walking. We then […]

C22. Avionics Full-duplex switched Ethernet (AFDX): Modeling and simulation

This paper develops a comprehensive simulation model for Avionics Full-duplex switched Ethernet (AFDX) network based on OPNET platform. Accordingly, the performance of AFDX networks is analyzed. The effect of frame size, switching delay and changing frames transmission order on the AFDX network performance are investigated. It is found that using faster switches and small frame size reduces […]

Quality of service evaluation of VoIP over wireless networks

The Voice over IP (VoIP) service demands high priority over other services and applications. Some constrains are associated with this real-time service, such as delay and throughput which need to be addressed before delivering to the customer. The mobility in IP networks is a demand that facilitates IP applications and services, especially in wireless networks. […]

A distributed energy efficient packet transmission algorithm for the IEEE802.11 WLAN

IEEE802.11 based WLAN networks are considered to be the default broadband access network supporting a range of traffic sources. In this paper a dual parameter based cost function is proposed which can be used to determine the transmission data rate for a transmitting WLAN device in order to maximize the energy efficiency of an infrastructure […]

Evaluation of cognitive radio for mission-critical and time-critical WSAN in industrial environments under interference

The evaluation of Cognitive Radio (CR) for Wireless Sensor and Actuator Networks (WSANs) in industrial wireless automation applications is presented in this contribution. Current wireless solutions do not ensure enough performance for hard real-time and reliability requirements, based on time-critical data traffic. These industrial applications are characterized by harsh environments, where the robustness of wireless […]
