| The thesis investigates how collective dynamics and network performance indicators of a packet switching network model are affected by changes in connection topology or packet routing schemes. In particular, we investigate the effects of its connectivity, periodicity of boundary conditions, and various levels of preferential attachment of additional links to the underlying network connection topologies.; packet switching network simulation model developed by A. T. Lawniczak, A. Gerisch and B. Di Stefano. Analysis is presented for a wealth of graphs of various network performance indicators obtained from the network model simulations. The network performance indicators analysed are: critical source load, path length, packet delay, number of packets in transit, packet speed, and throughput. In addition, we investigate the emergence of self-organization in spatio-temporal collective network dynamics. The results obtained in this thesis are applicable to wired, wireless and ad-hoc networks. |
