Priority management with clustering approach in Wireless Sensor Network (WSN)

摘要

Energy efficiency is considered as the key issue in the design of Wireless Sensor Networks (WSNs). Saving energy often introduces additional network delay, which is not desirable in case of critical application. For such application, the system should be time responsive. Most of the recent scenarios have not introduced any management of critical applications to their works in order to achieve energy efficiency. However, managing the critical data along with non-critical data is not often good for energy efficiency. Clustering is one technique that used very effectively to achieve scaling up and power saving in WSNs. In this work, we proposed a clustering scheme that able to manage critical or delay-sensitive applications with other best effort applications and meets both delay and energy constraints.
