Energy-Efficient Data Collection Protocol for Wireless Sensor Network Based on Tree

An energy-efficient data collection protocol for wireless sensor network based on tree (EEDCP-TB) is proposed in this paper. EEDCP-TB constructs data collection tree through the method of flooding avoidance and use the cascading timing scheme to allocate aggregation time in order to save node's energy; further more, this protocol introduce the node energy state parameter to meet energy balance to a certain extent when we choose forwarding nodes. Finally, compared with Flooding protocol and tree based data collection scheme (TBDCS), simulations show that the EEDCP-TB requires less transmission and receiving, saves node’s energy and prolongs network lifetime.
