An Application-Oriented Network Model for Wireless Sensor Networks
Wireless Sensor Networks (WSNs) are energy-constrained networks. The Residual Energy Real-time Monitoring (RERM) is very important for WSNs. Moreover, network model is an important foundation of RERM research at Personal Area Network (PAN) level. Because RERM is inherently application-oriented, the net-work model adopted should also be application-oriented. However, many factors of WSNs applications such as link selected probability and ACK mechanism etc. were neglected by current network models. These factors can introduce obvious influence on throughput of WSNs. Then the energy consumption of nodes will be influenced greatly.
