Abstract
A novel overlay based approach to enable hierarchical
routing in small world and scale free wireless networks
is provided and evaluated in this paper. In the solution,
the wireless short-cuts are applied as dynamic links
between overlay nodes, which apply bigger transmission
power to reach larger communication range. The effects of
such short-cuts into the end to end delay, route lengths
and throughput are studied by means of simulations. The
simulation results indicate that increasing the number of
referred wireless short-cuts lowers the end to end
delays, and makes the physical routes shorter, and also
improves throughput. When the clustering degree
increases, the physical routes become shorter and the
performance of the system improves. The simulations
carried out for evaluating the hierarchical routing
approach indicates the feasibility of the approach, and
the results also confirm quite well with small world and
scale free networks phenomenon. (15 refs.)
