An Analytical Study of Single and Two-slope Model in Wireless Sensor Networks

Presently there is a globally growing demand across all industries for small and portable electronic devices which feature Internet connectivity. This is largely due to their ease of use provided by robust interoperability and feasibility in almost any scenario. An example of such devices are the sensors used in a wireless sensor network (WSN) where prolonged battery life is a major challenge. This paper presents energy efficiency optimization techniques to reduce transmission power and further validate our findings through the use of single and double-slope modeling in MATLAB. In the simulations multiple aspects have been studied such as the connection quality, energy efficiency and optimal power with respect to distance and transmission power. The results have shown that the proposed optimization technique provides improvement to existing WSN technology (e.g. a 38.9% reduction in optimal power usage at the same pathloss distance).
