Abstract [en]

Cooperative communications (CC) and network coding (NC) are two emerging technologies in telecommunications. Extensive researches have shown that they are able and effective in the enhancement of energy efficiency, reliability and throughput of wireless sensor networks (WSNs). This project is aimed at realizing these technologies in a real WSN, an IEEE 802.15.4-based WSN testbed. It is conducted from theories to implementation, and then to tests/experiments, and the work on it is divided and presented  in two theses. This thesis is mainly focused on theories and experiments of WSNs and these two technologies, and the other one (by Nenghui Cui) on their realization and tests on the testbed. The testbed realizing CC and NC is built with Zolertia Z1 wireless sensor nodes that are based on IEEE 802.15.4, and the operating system, Contiki, that is specialized for WSNs. After the realization of CC and NC, the tests of the technologies on the testbed have been carried out, and the experiments designed and set up for their performance evaluations (packet reception ratio, number of transmissions, etc.) have been made. The test and experimental results have shown that CC and NC work properly, and they could enhance network performance like packet reception ratio and throughput.
