Özet:

The intracluster communication protocols of wireless sensor networks (WSNs) in the literature are designed according to time division multiple access (TDMA) with random slot allocations. This thesis proposes a novel scheduling algorithm for WSNs, in which cluster members (CMs) request time slots according to their energy predictions, and cluster head (CH) assigns these slots to members. The aim of this work is to increase the network lifetime by arranging the duty cycling of wireless sensor nodes. The simulations show that the proposed algorithm outperforms the intracluster communication protocol designed in LEACH. In addition, this thesis includes the implementation of a new communication technology, Bluetooth Low Energy (BLE), in a way to ensure energy neutral operation. BLE113 Development Kit transmits the advertisement packets, whose advertising intervals are arranged according to the energy harvesting pattern, to the BLE112 USB Dongle by Bluegiga. These advertisement packets also allow us to observe the conditions of the energy sources that power up BLE113 Development Kit. The tests conducted using this application in indoor and outdoor environments show that the throughput is maximized.
