The Comparison of Single-hop and LEACH Protocols in Wireless Sensor Networks

Based on the LEACH protocol and the Single-hop protocol, this paper proposes a new method to predict the lifetime and reliability of wireless sensor network directly. That is to say, the sensor nodes can be directly deployed without further simulation. Through a series of experiments to compare the two protocols have been several key conclusions: With the increase in sensor density, although the LEACH protocol life cycle is also increasing, but the maximum is always lower than the life cycle remains basically the same single-hop protocol. And compare the network reliability of the two can be seen, with the sensor density increases, LEACH protocol reliability is reduced. However, the reliability of the Single-hop protocol is always higher than that of the LEACH protocol. Thus, in this limited experimental environment, Single-hop protocol is better than LEACH protocol.
