“…In order to solve the issue of limited distances, an usual approach method is the usage of relay stations, where the data packets take multi hops from the source to the destination. [2] Under such conditions, packet forwarding, or routing, becomes necessary. The value of the radio transmission range affects network topology and energy consumption considerably.…”

The present paper presents considerations on using a low power routing solution for prolonging the battery life for motes within a wireless sensor network (WSN) without affecting the network connectivity. The solution applies for the cases when, the distances between motes and base stations are over the mote's communication range, and motes located between sinks and base station are commonly used both as regular motes and repeaters. This diminishes their energetic autonomy and increases lifecycle maintenance costs. The power constraint has a great impact on the functioning of wireless sensor networks; the battery life makes the data communication very high-priced and restricts the amount of transferred data. A quantitative study case is performed considering a wide-area WSN functioning in different modes.I.

This paper presents considerations of using wireless sensor networks for monitoring conditions within wind farms, taking into considerations the specific of such applications. In these scenarios, which are intended to cover a lot of ground or even operate in difficult radio environments with strong attenuation, the simple and direct communication between source and destination is not always possible, due to the distance restriction. To overcome these facts, there are required multi-hop algorithms considering the optimization of consumed energy, to enhance the network lifetime. In order to enhance overall network lifetime two methods were used, based on data aggregation and routing techniques.
