An Opportunistic Network is an extreme network
where the communication mainly depends on the mobility of the
participating nodes to address the intermittent connectivity. This
opportunistic routing utilizes a store-carry-forward paradigm
exploiting node mobility and local forwarding to transfer the
messages. The mobile nodes are normally low-power portable
wireless communication devices employing as wireless ad hoc
network for multi-hop transmission. With the limited resource,
the performance of the routing protocols can be degraded. Thus,
it is vital to consider the energy consumption of the mobile node in
this opportunistic environment, especially with different mobility
patterns. This paper aims to study and analyze the energy usage
on the node mobility. The results from the simulations show that
MapBased mobility models consume more energy than random
based mobility models while gaining higher delivery ratio. In the
random based models, random direction consume more power
than random waypoint and random walk respectively. |
