Lifetime-enhancement Schemes for Power-constrained Routing in Wireless Sensor Networks: A Survey

Notwithstanding the broad applicability of wireless sensor network (WSN), the successful development and deployment in various real-world applications is currently challenging. The node-devices are powered by constrained-batteries that are typically impossible to substitute after deployments. Therefore, WSNs are energy-constrained and liable to early failure while expected to run for long-terms without battery replenishments. Diverse researchers have recently presented specific lifetime enhancement routing solutions based on data aggregation technology targeted at reducing energy-consumption, and improving the communication reliability of various WSNs. This paper presents a brief survey of the research field of data aggregation-ware routing in energy-constrained WSN. The paper overviews and classifies various existing routing solutions based on their delivery models and also identifies some of their major drawbacks.
