The sensor nodes in a Wireless Sensor Networks (WSNs) are responsible to collect and share the sensed information, usually by making it available at a gateway point. In this context, network connectivity plays an important role as the nodes require the availability of a path to route the sensed data to the sink node. The main contribution of this work is to propose a cooperative communication strategy...
Wireless Sensor Networks (WSN) are characterized by their capacity of monitoring the environment, gathering and sharing information. Nodes in a WSN usually cooperate in the task of forwarding the sensed data to a sink node for later retrieval and analysis. The success of this task depends on the availability of efficient routes that meet the application requirements. As topology may change overtime,...
Wireless Sensor Networks (WSNs) have been considered in a number of different contexts, some of which may request the fast delivery of the sensed data to a gateway node. This work explores the use of Cooperative Communication (CC) and topology control to improve WSN connectivity while reducing the average end-to-end delay to route data items to a sink node. Two techniques are proposed in this work:...
