Selfishness in Opportunistic Networks

Introduction

Opportunistic networks rely on the mobility of their nodes and the sequences of their contacts to disseminate data. Proposed forwarding mechanisms represent different trade offs between data transfer speed and network resource consumption, most of them assuming perfect cooperation among network nodes. Nevertheless, nodes may behave selfishly often due to some resource preservation policy, in particular when they are constrained with respect to energy or/and storage space.

Task

In this project we assess the vulnerability of two popular data relaying alternatives, the unrestricted and two-hop relay schemes, to node selfishness. We use a simulator for opportunistic networks (ONE simulator from Helsinki University) with many different mobility models and relaying protocols and modify the protocols where necessary.
