TREEFP: A TDMA-based Reliable and Energy Efficient Flooding Protocol for WSNs

TDMA based Reliable and Energy Efficient Method for Flooding Wireless Sensor Networks. This invention relates to Wireless Sensor Networks, and more particularly to a TDMA based method of flooding in Wireless Sensor Networks that is reliable and energy efficient. The method comprises of forming a spanning tree of the network using sink of the network as root of the spanning tree with a plurality of non-leaf nodes; and assigning a slot to relay a control message within a control frame to the plurality of non-leaf nodes, wherein length of the control frame is minimized and all nodes of the network receive said control message by end of the control frame.
