Thesis title:
IMPLEMENTATION OF THE HEED CLUSTERING PROTOCOL WITH SLEEP SCHEDULING IN TINYOS 2 ON A WIRELESS SENSOR NETWORK TESTBED
By: CANAY ÖZKAN
ABSTRACT :
Energy e cient operation is often critical for wireless sensor networks (WSN), because network nodes operate on limited batteries. The aim of this thesis is to realize an implementation of an energy-e cient, scalable and competitive clustering protocol, HEED on MICAz motes using TinyOS 2 with further energy-e ciency enhancements. A working testbed is constructed, on which the network organizes itself to send periodic sensor measurements to a central station. In order to control overall energy consumption, power aware routing, topology control, time synchronization, sleep scheduling and transmision power adaptation problems are experimentally studied on the testbed.
