IMPLEMENTATION OF THE HEED CLUSTERING PROTOCOL WITH SLEEP SCHEDULING IN TINYOS 2 ON A WIRELESS SENSOR NETWORK TESTBED
By: CANAY ÖZKAN
Energy ecient 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-ecient, scalable and competitive clustering protocol, HEED on MICAz motes using TinyOS 2 with further energy-eciency 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.
