First, we discuss a QoS enhancement to a standard routing protocol, Dynamic Source Routing (DSR). By incorporating a new routing metric and the available bandwidth and delay estimation algorithms with DSR, we design a new routing protocol, QoSAware Source Routing (QASR), to meet the QoS requirements specified by Statement of Requirements (SoR) for public safety communications. We then evaluate the performance of QASR and the well-known standard routing protocols including Adhoc On-demand Distance Vector (AODV) and DSR based on real public safety scenarios using OPNET modeler at the 4:9GHz public safety spectrum band. Simulation results show that QASR significantly outperforms DSR and AODV in terms of various performance metrics. 2. Routing Protocols for Vehicular Ad Hoc Networks in Rural Areas Research on vehicular ad hoc networks (VANETs) has focused mainly on efficient routing protocol design under conditions where there are relatively large numbers of closely spaced vehicles. These routing protocols are designed principally for urban areas with high node density, fully connected networks, and are not suitable for packet delivery in a sparse, partially connected VANET.

In this paper, we examine the challenges of VANETs in sparse network conditions, review alternatives including epidemic routing and propose a Border node Based Routing (BBR) protocol for partially connected VANETs. The BBR protocol can tolerate network partition due to low node density and high node mobility.

The performance of epidemic routing and BBR are evaluated with a Geographic and Traffic Information (GTI) based mobility model that captures typical highway conditions. The simulation results show that under rural network conditions, a limited flooding protocol such as BBR performs well and offers the advantage of not relying on a location service required by other protocols proposed for VANETs.

Teaching EE 541 Advanced Communication Theory This course explores the principles needed for the design and analysis of communication systems. The goal is to provide the student a solid introduction to analog communications and a review of important mathematical foundation topics. Because of the increasing prevalence of digital communication technologies, emphasis will be given to communication techniques appropriate for the transmission and reception of digital signals. OPNET, Matlab and Simulink will be used in class problems. Examinations will be open book, open notes. The topical paper will analyze the modulation of an implemented communication system with reference to the course material.
