Energy efficiency is considered as the key issue in the design of WSN. Saving energy often introduces additional network delay, which is not desirable especially in case of sensitive-delay application. For such application, the system should be time responsive. Most of the recent scenarios have not introduced any management of delay-sensitive data applications to their works in order to achieve energy efficiency. However, managing the delay sensitive data along with regular 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. However, it does not take care of application delay constraints. In this work, we consider only two kinds of sensors, one is used for sensitive-delay application and the other one is used for best effort or regular application. The proposed clustering scheme manages both sensitive and best effort sensors and meets both delay and energy constraints.
