Cooperative Communication Mechanisms Applied to Wireless Sensor Network |
| Abstract: One of the major problems that still needs to be overcome in wireless sensor networks (WSN) is the unreliable nature of communication channels. In this PhD thesis, two types of communication techniques are addressed to minimize this problem: cooperative diversity and network coding techniques. Cooperative diversity techniques involve cooperation between nodes to improve the success rate of sent messages; and network coding techniques have been shown to be a promising solution to minimize the transmission delay, to balance the network load and also to improve the network throughput. In this context, this work intends to act upon these limitations by treating the relay node selection in a holistic way, combining both cooperative diversity techniques and the use of network coding algorithms to enhance the communication reliability in WSN networks. A relay selection technique based on multiple criteria to select the smallest number of relay nodes was proposed and evaluated through simulation and the network coding technique will be proposed and developed. Theses proposals will be evaluated by simulation and experimentally as well. | |
