Constructing Minimum Connected Dominating Set: Algorithmic approach
Connected Dominating Set is popularly used for constructing virtual backbones for broadcasting operation in WSNs. UD Graph is the most suitable model for a wireless sensor network. In this paper we provide an algorithm to find MCDS in UD Graph. It is based on the computation of convex hulls of sensor nodes or vertices. Constructing a virtual backbone in WSNs is an important issue because it red...
متن کاملConstructing Minimum Connected Dominating Set in Mobile Ad Hoc Networks
One of the most important challenges of a Mobile Ad Hoc Network (MANET) is to ensure efficient routing among its nodes. A Connected Dominating Set (CDS) is a widely used concept by many protocols for broadcasting and routing in MANETs. Those existing protocols require significant message overhead in construction of CDS. In this paper, we propose a simple, inexpensive and novel algorithm of comp...
متن کاملConstruction 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 کاملNear-Optimal Distributed Approximation of Minimum-Weight Connected Dominating Set
This paper presents a near-optimal distributed approximation algorithm for the minimumweight connected dominating set (MCDS) problem. We use the standard distributed message passing model called the CONGEST model in which in each round each node can send O(log n) bits to each neighbor. The presented algorithm finds an O(log n) approximation in Õ(D+ √ n) rounds, where D is the network diameter a...
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...
