A New Mobile Collaborative Approach Based Relays for Wireless Sensor Networks
Abstract
The main purpose for wireless sensor networks is especially for data collection. Nevertheless, since the sensors are mostly immobile, the operation of transferring data they captured to the base station is a critical task since the exchange environment is unstable. Our approach consists in injecting mobile relay nodes whose mission is mainly to maximize the lifetime of the network, also to provide connectivity between any sensor and the base station, and to minimize the latency of receiving data sent to the base station. Smart mobility is the key for our approach to ensure reliability by forming a virtual mobile circle using relay nodes. We have proved formally and by simulation the effectiveness of our approach, the obtained results prove the efficiency of our approach.
