Construction of minimum connected dominating set in wireless sensor networks using pseudo dominating set
In a wireless network, messages need to be sent on in an optimized way to preserve the energy of the network. A minimum connected dominating set (MCDS) offers an optimized way of sending messages. However, MCDS construction is a NP-Hard problem. In this paper, we propose a new degree-based greedy approximation algorithm named as Connected Pseudo Dominating Set Using 2 Hop Information (CPDS2HI),...
متن کاملConstruction of Minimum Connected Dominating Set in 3-Dimensional Wireless Network
Connected Dominating Set (CDS) has been a well known approach for constructing a virtual backbone to alleviate the broadcasting storm in wireless networks. Previous literature modeled the wireless network in a 2-dimensional plane and looked for the approximated Minimum CDS (MCDS) distributed or centralized to construct the virtual backbone of the wireless network. However, in some real situatio...
متن کاملDistributed Energy-Efficient Approaches for Connected Dominating Set Construction in Wireless Sensor Networks
Energy efficiency is one of the major issues in wireless sensor networks (WSNs) and their applications. Distributed techniques with low message and time complexities are expected in WSNs. Connected dominating sets (CDSs) have been widely used for virtual backbone construction in WSNs to control topology, facilitate routing, and extend network lifetime. Most of the existing CDS approaches suffer...
متن کاملAn Optimization Algorithm for Minimum Connected Dominating Set Problem in Wireless Sensor Network
One of the critical issues in wireless sensor network is the design of a proper routing protocol. One possible approach is utilizing a virtual infrastructure, which is a subset of sensors to connect all the sensors in the network. Among the many virtual infrastructures, the connected dominating set is widely used. Since a small connected dominating set can help to decrease the protocol overhead...
متن کاملMinimum Total Communication Power Connected Dominating Set in Wireless Networks
A virtual backbone of a wireless network is a connected subset of nodes responsible for routing messages in the network. A node in the subset is likely to be exhausted much faster than the others due to its heavy duties. This situation can be more aggravated if the node uses higher communication power to form the virtual backbone. In this paper, we introduce the minimum total communication powe...
