Simulation And Evaluation

WirelessHART is the most widely applied standard in wireless sensor networks nowadays. However, it does not provide any dynamic routing mechanism, which is important for the reliability and robustness of the wireless network applications. In this paper, a collection tree protocol based, dynamic routing mechanism was proposed for WirelessHART network. The dynamic routing mechanism was evaluated through several simulation experiments in three aspects: time for generating the topology, link quality, and stability of network. Besides, the data transmission efficiency of this routing mechanism was analyzed. The simulation and evaluation results show that this mechanism can act as a dynamic routing mechanism for the TDMA-based wireless sensor network.

Networking Protocols

The specific characteristic of underwater environment introduces new challenges for the networking protocols. Underwater Wireless Sensor Networks (UWSN) and terrestrial Wireless Sensor Networks (WSN) share some common properties but their differences necessitate specialized new protocols for successful underwater communication. In this paper, a specialized protocol, known as Directional Flooding Routing Protocol is being chosen as the protocol to implement the routing mechanism for underwater sensor networks (UWSNs). The protocol is analyzed and evaluated. Simulation experiments have been carried out to find the suitability of various protocols for the sub aquatic transmission medium, whether in freshwater or seawater. The goal of this paper is to produce simulation results that would illustrate the performances of the protocol for a given metric such as end-to-end delay, packet delivery ratio and energy consumption. By analyzing the simulation results, DFR is considerably reliable for UWSN because this protocol is suitable for the sub aquatic transmission medium such as seawater.
