Constructing Wireless Sensor Network Model Based on Small World Concept
In order to improve the energy cost of data transmission in wireless sensor network (WSN), we propose a new method to construct wireless sensor network topology based on small world concept. We add some certain high energy nodes (H-sensor) in the network and create a few of long-range links between the sink and H-sensors, called shortcuts which act as the long links required in small world network. We also give the answer to determine the optimal number and placement of the H-sensors. The simulation shows that this small world WSN brings down the average path length. It reduces node energy consumption and data transmission delay and increases network throughput.
