Dynamic/Static Clustering Protocol for Wireless Sensor Network

Wireless sensor networks consist of a large number of small, low-cost and low-power nodes that coordinate with one another for environmental sensing. The sensor nodes are restricted in power, memory and computational resources. There is a need to design protocols that adapt much better to the constraints of the sensor network environment. In this paper, we propose clustering protocol called dynamic/static clustering protocol DSC by extend LEACH-centralized (low-energy adaptive clustering hierarchy). The clusters in our scheme are fixed for 10 rounds then the clusters formation take place again. We compare the performance of DSC with LEACH-C. Our experiment results show that DSC outperforms LEACH-C in term of communication overhead, network lifetime and energy dissipated over time.
