Session Initiation Protocol Server Implementation For Linksys Routers, Matthew Duder

Computer Science and Software Engineering

Session Initiation Protocol (SIP) is a signaling protocol used for network-based media interaction. SIP Servers are required to process and forward requests and responses between end clients. Once connection setup is complete, the end clients utilize some other protocol (such as Real-Time Transport Protocol) to complete their task.

Such a server may be implemented and installed on routers. Unlike the SIP protocol, however, router development currently remains without standards. For this project, Linux-based residential-grade routers had their kernels replaced with an open source version. This allowed for installation of open-source development, such as a SIP server implementation.

This project led …

General Direction Routing Protocol, Sean Michael Lydon

Master's Theses

The General Direction Routing Protocol (GDRP) is a Wireless Sensor Network (WSN)

multi-path routing protocol which abstracts localization information (commonly GPS

coordinates) into relative direction information in order to perform routing decisions. By

generating relative direction information GDRP is able to operate with fewer precision

requirements than other protocols. This abstraction also allows the integration of other emerging

hardware-based localization techniques, for example, Beamforming Sensor Arrays.

GDRP does not specifically address the next hop a packet should take, but instead specifies a

direction it should travel. This direction abstraction allows for multiple paths to be taken through

the network thus …

Store And Forward Routing For Sparse Pico-Satellite Sensor Networks With Data-Mules, Trevor Joseph Koritza

Master's Theses

Satellites are playing an increasingly important role in collecting scientific information, providing communication services, and revolutionizing navigation. Until recently satellites were large and very expensive, creating a high barrier to entry that only large corporations and government agencies could overcome. In the past few years the CubeSat project at California Polytechnic University in San Luis Obispo (Cal Poly) has worked to refine the design and launching of small, lightweight, and less expensive satellites called pico-satellites, opening space up to a wider audience. Now that Cal Poly has the launch logistics and hardware under control, a new problem has arisen. These …

Internet-Scale Reactive Routing And Mobility, Daniel B. Nelson

Master's Theses

Since its commercialization, the Internet has grown exponentially. A large variety of devices can communicate creating advanced services for a diverse ecosystem of applications. However, as the number of Internet hosts has grown, the size of routing tables required to correctly route data between them has also increased exponentially. This growth rate necessitates increasingly frequent upgrades to routing device hardware, providing them with additional memory for fast-access storage of route information. These upgrades are both physically and fiscally untenable, and a new Internet routing solution is necessary for future growth.

This research focuses around an incrementally deployable, reactive routing system …
