We tested the energy consumption behaviour of three poweraware
route selection protocols, namely the Minimum Total
Transmission Power Routing (MTPR), the Min-Max Battery
Cost Routing (MMBCR) and the Conditional Max-Min Battery
Capacity Routing (CMMBCR). Extensive simulations under
different MANET scenarios (e.g., mobility, node density)
showed the importance of considering the overhearing as part
of the energy model.
When considering the overhearing, all protocols behave similar
with respect to the expiration time of nodes and connections,
because of the limitation of routes available. On the other hand,
when we don’t consider the overhearing activity, we show the
importance of network density in route selection when trying to
prolong the lifetime of both nodes and connections.
In dense networks, because of the availability of several
routes, the MTPR allows the connections to live longer since
it reduces the overall energy consumption. As for sparse networks,
the role of nodes for avoiding the network partition is
more crucial. Thus, networks can take advantage of the MMBCR
allowing the nodes to live longer.
To conclude, we could state that, since network interface
cards in near future could allow nodes to switch themselves into
on and off states with low cost in terms of energy consumption
and transition time, some approaches that combine the sleeping
mode with the appropriate route selection mechanisms should
be developed to extend the lifetime of both nodes and connections.
