- Abstract:
- Since communication and data transmission present the most energy consuming task in Wireless Sensor Networks (WSNs), cluster-based routing protocols emerged as significant solutions for the energy conservation problem. In this paper, a fault tolerant based unequal clustering algorithm is proposed to extend the network lifetime of wireless sensor nodes. A threshold value is fixed to avoid the re-clustering process in some rounds leading to reduce the total number of data packets. The performance of the improved clustering algorithm is carried out with the network simulator NS3. A comparison between both unequal clustering with and without fault tolerant technique shows that avoid holding the selection of CHs in some rounds achieves better performance in terms of energy consumption and network lifetime.
