Network-level Performance Enhancement in WirelessNanosensor Networks
through Multi-layer Modifications
Abstract:
Researchers consider wireless nanosensor networks (WNSNs) as a revolutionary
emerging network paradigm from the point of its diversified applications and
contributions to the humanity. Existing research in this field is still in elementary stage
and performance enhancement via designing protocol suit represents a potential issue
to address for this field. However, most of the studies in the literature mainly focus on
lower layers, i.e., Physical and MAC layer protocols leaving upper layers such as
Network layer and Transport layer protocols still unexplored. Therefore, in this paper,
we explore performance enhancement in WNSNs via modifications in the existing
network and transport layers protocols. In this paper, we devise a hierarchical AODV
routing protocol and an acknowledgement-based UDP protocol for WNSNs. We
perform rigorous simulation in ns-2 to prove the efficacy and efficiency of our proposed
mechanisms. Our simulation results reveal significant performance enhancement in
wireless nanosensor networks for our proposed protocols.
