Reuse and Improvement of Peersim Open Source Packages
This paper presents the reuse of two open source implementations of P2P protocols for Peersim simulator. Firstly, we will present the new implementation of Chord, which is considered as the most popular P2P protocol among the structured family of P2P networks. In this latter, the search requests generally use a Data Hash Table (DHT) to find a requested resource. This kind of systems is generally known as Structured and Informed Protocols. In this context, to improve the search mechanism of Chord, we modify its open source implementation for Peersim to introduce another type of resource search that supports semantic and blind requests. The main objective is to show how we have modified the open source code to achieve our goals. Also, in this paper, we will present how we have improved the display of results by the Peersim simulator through another open source package that implements Cloudcast protocol.
