Hierarchal Energy Efficient Network Protocol for wireless sensing

The usage of wireless sensor networks applications is becoming very important in monitoring and analyzing the environment by utilizing a number of sensor nodes. These sensing nodes are capable of collecting the required data and transmit it to the target application. The wireless sensor nodes use routing protocols for sending data between the nodes of the system as required by the application. These routing protocols vary in their effect on the node power consumption, the node life time and the system scalability. We propose a Hierarchal Multipath Adaptive Periodic Threshold-sensitive Energy Efficient Network Protocol (HMAPTEEN). The protocol uses selected nodes in each level for routing to the next level. It also allows multiple routes for the information to reach their destinations. The hierarchal approach decreases the power consumption and increases the life time of the network in addition to improving the routing reliability.
