摘要：The Wireless Sensor Network (WSN) consisting of a large number of sensors are effective for gathering data in a variety of environments. Since the sensors operate on battery of limited power, it is a challenging aim to design an energy efficient routing protocol, which can minimize the energy and thereby extend the lifetime of the network. However, in the context of Wireless Sensor Networks routing, Connected Dominating Set (CDS) principle has emerged as the most popular method for energy efficient topology control (TC) in WSNs. A virtual backbone is formed in a CDS-based topology control technique, which allows communication between any arbitrary pair of nodes in the network. In this paper, we present a CDS based topology control algorithm, TC1, which forms an energy efficient virtual backbone. In our simulations, we compare the performance of TC1 with three prominent CDS-based algorithms namely energy-efficient CDS (EECDS), CDS Rule K, A3 and A3 Lite algorithms. The results demonstrate that TC1 performs better in terms of Residual Energy and other selected metrics. Moreover, the TC1 not only achieves better connectivity under topology maintenance but also provides better sensing coverage when compared with other algorithms.
