The coal mine laneway is a kind of limited and changeable space with bend and embranchment in a longitudinal way. Its complicate environmental condition influences the connectivity, coverage, the packet loss rate and energy consumption of the wireless sensor networks. To construct the real system of wireless sensor networks for mine working environment, this paper proposes a clustering-based chain-type...
Among many issues to be considered in designing an ad hoc wireless sensor network the key issue that stands out is to employ an efficient weighted topology discovery algorithm based upon certain node parameters. In the paper, we have described an algorithm for weighted topology discovery which uses colors based approach to partition the network in to clusters. Each cluster has a clusterhead. The nodes...
Network scalability and energy efficiency in wireless sensor networks should be supported by elaborate topology control. Clustering algorithms are useful topology management approach to reduce communication overhead and exploit data aggregation in wireless sensor networks. A clustering algorithm based on cell combination is presented in the paper for the networks where sensor nodes are distributed...
Energy limited is one main bottle-neck for wireless sensor networks. Due to unreasonable cluster head electing and intensive energy consumption of cluster head in clustering algorithm, we propose multi-hop clustering algorithm, which is aimed to optimize cluster head voting and balance energy consumption of cluster head. Theoretical proofs and Simulation results show that our algorithm has a better...
Wireless sensor networks(WSNs) are very important for monitoring underground mine safety. Aimed at the characteristics of structure of the tunnel in underground mine, the tunnel wireless sensor network (TWSN) is presented to monitor the tunnel. TWSN has the unbalanced communication load which leads to early invalidation of nodes close to the base station. The nonuniform clustering algorithm for TWSN...
The clustered topology is an important mechanism for WSN (wireless sensor networks) to balance the energy consumption, extend the network lifetime, enhance the management efficiency and improve the network scalability. It adapts to use in large scale deployment. CPK (Combined Public Key) algorithm produces public/private keys offline, and the trusted third party is not necessary for the authentication...
One of the most important constraints on wireless sensor network is the low power consumption. Therefore, topology of wireless sensor network must focus on power conservation. It is possible to extend the lifetime of a network by controlling its topology through clustering. Topology control target tracking-oriented based on overlapping clustering in wireless sensor network is proposed in this paper...
Zigbee technology is here to stay. With current market trends it is to be understood that it will play a vital and major role in low rate wireless personal area networks. Zigbee networks facilitate numerous applications such as consumer electronics, home area networks, health care monitoring and environmental monitoring. Effective routing in wireless sensor networks is critical to conserve energy...
Clustering has been proven to be an energy efficient topology for wireless sensor networks. It is a key topic to rotate the role of cluster-head to balance the energy load and extend the network lifetime. This paper proposes an estimated energy based adaptive clustering protocol (EEAC), which adopts energy driven cluster-head rotation strategy, selects new cluster-head in local cluster according to...
Topology Control and energy saving is one of the most important challenges in wireless sensor networks because of Special characteristics of these networks such as limited transmission range, low bandwidth, limited power resource and the impossibility of recharging.

Considering characteristics of wireless sensor networks,control mechanisms must be scalable, adaptive, robust, fully distributed, and self-organizing. In this paper, we focus on topology control for periodic data gathering, which certainly is one of typical applications of WSNs. We propose a novel mechanism based on a biological self-organization mechanism, that is, a reaction-diffusion model, to...
For node-intensive sensor networks, hierarchical topology control can effectively save energy. Based on the existing two-layer model, we propose a logical three-tiered topology control model which consist of relay nodes(RNs), application nodes(ANs) and sensor nodes(SNs). Under this architecture, the goal of lower-tier SNs is to sense the playing fields and middle-tier ANs only neeed to gather data...
The energy consumption problem in wireless sensor networks is investigated. The problem is to expend as little energy as possible receiving and transmitting data, because of constrained battery. In this paper, in order to extend the lifetime of the network, we proposed a location-based clustering algorithm for wireless sensor network with skewed- topology. The proposed algorithm is to deploy multiple...
