A Tree-Based Energy-Efficient Collision-Free MAC in Wireless Sensor Networks
The rapid proliferation of miniature wireless networking technologies drives to devise different sensor network applications with diverse QoS requirements. Achieving higher reliability is one of the major requirements for different loss-intolerant applications such as industrial process control, battle-field surveillance etc. On the other hand, providing higher energy efficiency also carries paramount importance in the context of resource constrained WSNs. Being motivated on these, in this paper, the authors propose an energy efficient and collision free MAC for WSNs which exploits the routing tree which is formed in many-to-one based data dissemination scheme in WSNs.
