Topology control tries to provide more spatial reuse and power conservation while keeping network connectivity. Some topology control algorithms try to provide more energy conservation by sleeping the redundant nodes. This paper presents a learning automata based algorithm to determine whether the node has to sleep or not. Just few efforts have focused on the issue of topology control with mobility...
In WSNs, energy conservation is the primary goal, while throughput and fault tolerance are other important factor. According to wireless sensor network nodes energy consumption, hardware failure and communication factors, in this paper, an evolving network method based on complex network theory of small-world Kleinberg model is proposed, which uses long links and short links in partial view information...
Clustering offers a kind of hierarchical organization to provide scalability and basic performance guarantee by partitioning the network into disjoint groups of nodes. In this paper an energy efficient clustering algorithm is proposed under large-scale mobile sensor networks scenario. In the initial cluster formation phase, our proposed scheme features a simple execution process, which has a time...
In recent years, there has been a growing interest in wireless sensor network. In wireless sensor network, constrained energy is one of the most critical problems. In-network data aggregation is essential for the efficient operation of wireless sensor network. In this paper, we propose a novel energy saving topology control algorithm (ESTP). This scheme enable the node within a given distance cooperate...
Wireless sensor networks (WSNs) are emerging as essential and popular ways of providing pervasive computing environments for various applications. In all these environments energy constraint is the most critical problem that must be considered. Clustering is introduced to WSNs because of its network scalability, energy-saving attributes and network topology stabilities. However, there also exist some...
Because of the limited battery power of wireless sensor network node, energy conservation is a key issue. This paper improves LEACH algorithm. Through taking into account the energy state and one-hop neighbor nodes of nodes, the improvement algorithm optimizes cluster head selection, and effectively reduces the possibility that the low energy or poor location nodes are elected the cluster heads, further...
