In wireless sensor networks, the routing
algorithms currently available assume that the sensor nodes are
stationary. Therefore when mobility modulation is applied to the
wireless sensor networks, most of the current routing algorithms
suffer from performance degradation. The path breaks in mobile
wireless networks are due to the movement of mobile nodes, node
failure, channel fading and shadowing. It is desirable to deal with
dynamic topology changes with optimal effort in terms of
resource and channel utilization. As the nodes in wireless sensor
medium make use of wireless broadcast to communicate, it is
possible to make use of neighboring node information to recover
from path failure. Cooperation among the neighboring nodes
plays an important role in the context of routing among the
mobile nodes. This paper proposes an enhancement to an existing
protocol for accommodating node mobility through neighboring
node information while keeping the utilization of resources to a
minimum.
