An Enhanced Optimal Selective Forwarding in Band Based Broadcast Scheduling for Effective Energy Saving in Wireless Sensor Networks

S. Kannan, V.P. Arunachalam and S. Karthik


In the context of wireless sensor networks, nodes have limited energy and forward messages of different importance. An algorithmic technique called band-based directional broadcast is used to control the direction of broadcasts that originate from the sensor nodes. A key challenge is how to gather the sensor data in a manner that is energy efficient with respect to the sensor nodes that serve as sources of the sensor data. In the research, an optimal selective forwarding scheme is introduced in order to save energy in wireless sensor networks. The goal is to direct each broadcast of sensor data toward the mobile sink, thus reducing costly forwarding of sensor data packets. The technique is studied by simulations that consider energy consumption and data deliverability.
