Cross-layer Optimization Protocols in Ad-hoc Networks: Analysis and Practical Implementation of Transport and Network Layers (Electronics Project)

Ad-hoc wireless networks use multi-hop transmissions to communicate, without exploiting any infrastructure. Logical links create unreliable connections between nodes: the capacity of the channel can unpredictably change due to the Continue reading

Wireless Network Cocast: Cooperative Communications with Space-Time Network Coding (ECE/EEE Project)

Traditional cooperative communications can greatly improve communication performance. However, transmissions from multiple relay nodes are challenging in practice. Single transmissions using time-division multiple access cause large transmission delay, but simultaneous transmissions from two or more nodes using frequency-division multiple access (FDMA), code-division multiple access (CDMA), or Continue reading

Mini-UAV based Sensory System for Measuring Environmental Variables in Greenhouses (Electrical/Electronics Project)

ABSTRACT

This paper describes the design, construction and validation of a mobile sensory platform for greenhouse monitoring. The complete system consists of a sensory system on board a small quadrotor (i.e., a four rotor mini-UAV). The goals of this system include Continue reading

Using a Random Secret Pre-Distribution Scheme to Implement Message Authentication in VANETs (Electrical/Electronics Project)

ABSTRACT

In recent years, the development of the Intelligent Transportation System (ITS) has increased the popularity of vehicular ad hoc networks (VANET). A VANET is designed to enable vehicles to exchange information a bout traffic or vehicle conditions Continue reading
