Propagation Loss Aware Routing in Wireless Nanosensor Networks Having Directional Nano-Antennas
2017 IEEE 42nd Conference on Local Computer Networks (LCN)(2017)
摘要
Communication overWireless Nanosensor Networks (WNSNs) is envisioned to experience different challenges due to having unique features such as specialized nano-antenna behavior, short transmission range, limited operating capabilities, etc. Among all these features, nano-antenna behavior plays a noteworthy role on overall network-level performance. To the best of our knowledge, the role is yet to be investigated in the literature from the perspective of directional nano-antenna. Therefore, in this paper, we present a model of directional nano-antenna and analyze behavior of the nano-antenna through simulation conducted by CST microwave studio. Furthermore, using directional nano-antennas, we propose a new propagation loss aware routing protocol for WNSNs with a view to ensuring minimum path loss along with a delicate balance among different network-level performance metrics such as throughput, end-toend delay, and energy consumption. In addition, to evaluate the performance of our proposed protocol and compare that against the performances of existing alternatives, we incorporate the nano-antenna model and our proposed protocol in ns-2 simulator after performing necessary customizations in the simulator. We perform rigorous simulation in ns-2 and confirm efficacy of our proposed protocol through the simulation results.
