Bachelor Thesis / Studienarbeit Overlay Implementation of Virtual Cord Protocol (VCP) Description: Distributed Hash Tables (DHTs), which are also called structured peer-to-peer (P2P) networks are efficient techniques for data management in distributed systems such as file sharing in the internet. The idea of DHTs is simple: DATA items are associated with numbers and each node is responsible for range of these numbers. This way, it is easy to find the responsible node who stores a specific data item. Usually, DHTs are built on the application layer and rely on an underlying network routing protocol that provides connectivity between the nodes. Virtual Cord Protocol (VCP) is based on the idea of DHTs and it was originally designed to be used in Wireless sensor network. It provides both routing and data management services. A typical join process in VCP is shown below (left: underlay Right: overlay).

Tasks: The goal of this study is it to re-design and implement a simulation model for VCP as overly in OMNeT++. Therefore, the joining node must contact a node in the system to get a position and to build its routing table. The implementation can be done using the INET framework, which contains well-tuned models for several l wired and wireless networking protocols such as TCP, OSPF, Ethernet, and WLAN.
