Wireless sensor networks (WSN) have recently used in many applications like surveillance, military applications, etc. In such applications, the sensor nodes are expected to be work long period of time without recharging their batteries. To extend the network lifetime, some sleep scheduling techniques always used, which may cause communication delay in large scale WSNs. In this paper, Although the existing system avoids delay there are still few challenges. So the proposed topology of a wireless network should be efficiently designed to achieve high network performance. Thus remove useless topology information such as collision, redundancy and transmission delay from a network to dramatically improve a network’s broadband utilization, delivery ratio, network lifetime and packet retransmission. This is called as topology control management. Thus Connected Dominating Set (CDS) is regarded as an effective approach to hierarchical topology organization.
