Abstract

.Wireless Sensor Networks importance is rapidly increasing and becoming a vital element in the process of gathering information in almost every scientific and practical aspect, but since the sensor node is usually a small device and has a battery with very limited life, power consumption is turning out to be the main drawback of this significant technology thus a lot of work and researches is going on to find new ways to reduce the power needed to operate those sensors. One of the main power consuming functionality of this technology is the wireless transmission of the data that the sensors collect across the fields [5][6]. In order to overcome this restriction, many proposals have been made to create an optimal algorithm that can guide the way each sensor node transmit it's data in order to reduce the power needed for the transmission process. This research focuses on creating a simplified scheduling algorithm that can break up the transmission waves into chains of nodes, so that each node transmits the data that has been collected to the best available node around, and so on till the information is propagated to the main server that collects all the information and analyze them.This newly proposed algorithm takes many attributes into considerations, but the main ones are the geographical information and the load that each senor node carries. A simulation model has been created to verify the effectiveness of the algorithm and to compare how close the results to the ideal network configuration are.
