A Performance Analysis of an Ad-hoc Ocean Sensor Network

Abstract

This thesis presents the simulation results and performance analysis of IEEE 802.15.4 in an oceanic environment. The 802.15.4 standard allows simple sensors and actuators to co-exist in a single wireless platform. The simulation is performed using Network Simulator, version 2 (NS2) which is an open-source network simulator tool. NS2 is an event driven network simulator developed at UC Berkeley that simulates a variety of networks. Leveraging on the capabilities of NS2, the performance of the IEEE 802.15.4 protocol has been studied based on variations in node density, mobility as well as loading conditions. The mobility model selected for the simulation has considered the ocean effects on the mobile nodes, in particular the surface current. However, the available mobility models (Random Waypoint, Gauss-Markov, Manhattan Grid and Reference Point Group) do not represent the real life mobility in an oceanic environment scenario. As a result, actual data of surface measurement in the Monterey bay area is used to generate the node movements. The results from this analysis provide insights into the performance of IEEE 802.15.4 and its suitability for operating in an oceanic environment.
