The advantage of the above protocols is that they can be adapted to any type of WSN application. Interestingly, without a specific application and its requirements, we can see that each protocol deals with some requirements and ignores others. None of the existing protocols deals with specific requirements simultaneously like Energy efficiency (and subsequently network lifetime), reliability, real time responsiveness, scalability and reactivity. Thus, the application of these protocols in a specific application of forest fire detection (which requires to meet all the aforementio

ned requirements) may not result in the best performance. The advantage of the proposed RPLS protocol over the existing ones relies on its ability of being an application-specific routing protocol and thus it meets the objectives and enhances the performance of the WSN application for which it is designed for. But the security problem requires even more effort to avoid false alarms and thus not affect network performance particularly in terms of energy and time.
