Wireless sensor networks are currently being used in many monitoring applications. Often, all the data collected by the sensor nodes deployed in the field must be timely and reliably transferred to a single sink node. For this purpose, the network is organized in a tree-like topology. Following the initial deployment, an initialization procedure aims at establishing a reliable network communication infrastructure. This paper presents Kick-Off, an initialization procedure for convergecast in wireless sensor networks. Kick-Off performs neighbors’ discovery, defines a tree-like topology by evaluating and selecting the most reliable links over the worse ones, achieves an accurate time synchronization of the nodes composing the network, and includes a symmetric key generation and distribution scheme to secure data transmission. The proposed initialization procedure can be specifically tailored for e.g. minimizing the network setup time, as in surveillance and emergency response scenarios, or for evaluating in detail the quality of the links among the nodes, as in environmental and industrial process monitoring applications. The performance of Kick-Off is demonstrated through experimental results on a network deployed inside a university building.
