Design and Evaluation of Self Organizing Protocols for Wireless Networks


Abstract

In this project, we are investigating the medium access control aspect of a self-organizing protocol.  This work extends our previously developed routing algorithm for an evolving wireless network of low-cost nodes with varying transmitting powers and arbitrary topology.  To capitalize on our structure, we are designing a scheme for the medium access control (MAC) layer of the network.  The scheme entails minimal MAC logic in the low-cost nodes and requires a single frequency to operate.

As a second area of research, we are considering the design and optimization of multiple-layer networks, which are important for overcoming reliability and congestion problems that may develop in a single-layer centrally controlled network.  A multiple-layer network entails multiple roots that must operate at a different frequency.  Thus, optimal root placement and layer scheduling algorithms are being designed.  We are also developing self-healing protocols for single-layer and multiple-layer networks.
