Wireless sensor networks have arisen as the natural evolution of the great development that radio communication integrated circuits have achieved. This kind of networks are formed by several wireless and autonomous nodes that are able to sense their environment and work in an unattended fashion for long periods of time without human intervention. In order to achieve this performance, these nodes have to efficiently manage their power resources, both in sensors signal sampling and in data transmission. These networks offer a wireless way not only to capture the information but also to collect it wirelessly. This performance offers a synchronized picture of the value of each and every sensor in the network.

Many different medium access control protocols for wireless sensor networks have been published in the last few years. Although these approaches allow managing the medium access of all the nodes, none of the existing implementations at the moment of writing this thesis offered an integrated solution with ordered, reliable and power-aware data collection.

The purpose of this thesis is to propose and develop a brand new medium access control protocol for wireless sensor networks. The main aim of this protocol is to reduce the network’s data collection delay. This objective will be achieved by allocating different time slots to each node in the network. Additionally, some tests over real physical sensor networks have been performed in order to validate the theoretically obtained results.
