Energy efficient source based tree routing with time stamp in WSN

Wireless sensor network most recently used technology. Different routing protocols and topologies are used to transmit data from source to sink. A tree based routing technique is based on tree topology whereas parent-child relationship is used to forward the packet. Security is also a major issue in transmission that should be considered. A packet that is transmitted from source should be reached to destination in pre-specified time period. Some security mechanism should be applied and some parameters should be added with each data packet that is to be transmitted.
