Impact of Broadcasting Directions in SDLS for Wireless Sensor Networks

In this paper, we discuss Sink-oriented Dynamic Location Service (SDLS) in wireless sensor networks. Since the data is collected by mobile sinks in sensor networks, sink and source must broadcast the information of locations to transfer data from a source node to a sink. To make source can built an efficiently forward data from a source node to a sink, we will discuss the direction of broadcasting in different number and angle and compare energy consumption and data success ratio with each other. From simulation results, we can find the method with lower power consumption and better data success ratio transmission in wireless sensor networks.
