Wireless sensor network (WSN) energy efficiency challenge from implementation perspectives

Through review of current Wireless Sensor Network (WSN) energy preserving techniques used in industry and academic research, we recognize that the integration of various techniques through implementation is a challenging task due to application specific nature of system integration. On one hand, most researches on energy efficiency focus on one single layer with perfect assumptions about other layers and environment parameters. While this methodology will simplify the design process and provide valuable insight into single layer solution, such approach cannot provide information on layer incompatibilities between different sets of protocols, nor will give information on the overall performance of a network based on the protocols under test. Further more, under various non-standard assumptions, the real contribution of these proposed optimization methods are difficult to be achieved if not impossible. Hence industry professionals become very cautious to integrate diverse and advance ad hoc solutions into their products and standards. To show credibility of the ad hoc solutions and their implications on industry applications, researchers have to evaluate their solutions under a generic architecture Which can test different scenarios and evaluate performance based on a wide range of metrics.
