PEERSIM

PEERSIM

PEERSIM is A better simulation environment for P2P protocols named. These kinds of simulations are coded with the Java programming platform. The Peer-to-Peer simulator is also called as Peersim. An easy configuration, extendability, and high performance are the main features provided by the Peer-sim.

Implementing testbed of heterogeneous cluster using Peersim simulator
  • Both dynamic and scalable designs are used in Peer-sim technology. The modular approach is used in Peer is the main philosophy of the preferred way of coding with it is to re-use existing modules. The modules used in Peer-sim can be of different kinds. For example, the construction and initialization of the underlying network are moduled. The different protocols are handled by this module, which controls and modifies the network in Peer-sim.
  • Our organization’s main motto is to provide a cent percentage of client’s satisfaction with the expected cost value. Our employee development team members are very enthusiastic and give their full support to the organization’s development.
  • Peersim offers a lot of these modules in its sources, which greatly ease the coding of new applications. A peer can also work in two different modes: cycle-based or event-based. The cycle-based engine is based on a very simple time scheduling algorithm and is very efficient and scalable. However, it has some limitations. Peer to peer simulator can achieve a network consisting of 10^6 nodes using the cycle-based engine. As an example, it does not model the transport layer.
  • The event-based engine is based on a more complex but more realistic approach. It is not very used. It is not well documented, and its performances are quite unknown. Both these points are what we had to investigate during our project.
  • Extremely, a large scale (millions of nodes) systems are called Peer-to-peer (P2P). Continuously, nodes in the network can join and leave from the network. In such an environment experimenting with a protocol is no easy task at all. The cope with these properties and to reach extreme scalability and to support dynamism are developed by the peer to peer.

Peer-to-peer

  • In addition, the simulator structures easy to quickly prototype a protocol and are based on component and make it. In fact of Java objects, the different pluggable building blocks are combined with the protocol. The two different simulation models are supported by the peer to peer 1.0 version: the cycle-based model and a more traditional event-based model. This document is about the former, and this model is defined as a simplified one. At the cost of some loss of realism, the extreme scalability and performance are achieved by this model. Several simple protocols can create this loss without problems, according to our own experience; yet, care should be taken when this model is selected to experiment with a protocol.
  • The modular programming based on objects (building blocks) is encouraged by Peersim. Each block easily replaces the same interface (i.e., the same functionality) implementing another component.

The general idea of the simulation model is

  • Choose a network size (number of nodes)
  • Choose one or more protocols to experiment with and initialize them.
  • Choose one or more Control objects to monitor the properties you are interested in modifying some parameters during the simulation (e.g., the size of the network, the internal state of the protocols, etc.)
  • Run your simulation invoking the Simulator class with a configuration file that contains the above information
