QoS analysis of hierarchical routing protocols for wireless sensor networks
2017
In wireless sensor networks, sensors must have a high degree of autonomy to ensure a continuous monitoring of the phenomenon perceived and must transmit the best of information to the base station with minimum loss of it. Cluster based routing protocols were initiated as the most energy efficient routing protocols for large scale wireless sensor networks. With the trend of multimedia and real time applications, the quality of service becomes one of the main requirements of WSNs. The purpose of this paper is to compare some cluster-based routing protocols, differentiated in the data transfer strategy, according to some QoS metrics such as: energy, delay, and bandwidth. These protocols are LEACH, CBHRP, MH-LEACH and LEATCH. Simulations results have shown that the best routing protocol is CBHRP because it realizes the best tradeoff between all metrics
