[Industry research] Novel_Method_for_Optimal_Number_of_Cluster_Heads_ DL : 0: Abstract: The optimal number of cluster heads is an important parameter of wireless sensor network performance. Network nodes will consume more energy if the number of cluster heads is too much or too little. This paper focuses on novel calculation method for ptimal number of cluster heads. Base on the analysis of LEACH energy dissipation model,novel lation method is derived from the total energy dissipation of a round. Simulation shows the relationship of the optimal number of cluster heads, the number of frames in steady state phase and the distance between cluster heads and base station (BS).And it provides a theoretical basis for calculation of optimal number of cluster heads which can reduce the energy consumption among nodes and achieves an improvement on the network lifetime.

[Program doc] A-new-clustering-method-to-prolong-the-lifetime-o DL : 0: One of the most critical issues in the wireless sensor networks is the network s nodes limited availability of energy. The network lifetime strictly depends on its energy efficiency. Clustering is a method to make the consumed energy efficient. LEACH is one of the fundamental clustering algorithms. In this paper we have proposed an algorithm which extends LEACH by considering number of neighbors and remaining of the energy of each node to be a cluster head. We have also proposed to use gateway nodes in each cluster to enable the cluster head to reduce its transmission radius within the cluster to achieve better power saving. We analyze and compared the proposed algorithm along with the LEACH, LEACH-c and MIMO the most recent extend over the LEACH and show that the proposed algorithm can prolong the lifetime of the network.

[Program doc] 05552317 DL : 0: In wireless sensor networks, the power resource of each sensor node is limited. Minimizing energy dissipation and maximizing network lifetime are important issues in the design of routing protocols for sensor networks. In this paper, Cluster routing protocol LEACH (Low-Energy Adaptive Clustering Hierarchy) is research and improved. We extend LEACH stochastic cluster-head selection algorithm via changing the round time According to the situation of sensor network. It is named Variable-round LEACH. The result simulated in NS2 shows that the energy is significantly reduced and the lifetime of the whole network is increased compared with the previous routing algorithm for the sensor networks.

[Other Embeded program] eploying-Sensor-Nodes-in-WSN DL : 0: 论文:在无线传感器网络中,传感器节点收集本地数据,通常通过其它节点将数据转发给基站,因而离基站越近的节点,消耗的能量越多.如果采用通常的方法,即均匀布置传感器节点,则基站附近的节点将很快消耗完能量,基站也就无法收集数据.本文通过研究无线传感器网络中的能量消耗,得到了一个布置传感器节点的密度函数,按此函数布置传感器节点可以有效地延长系统的生命期.理论分析和模拟结果表明,本文的布置方案将系统生命期提高到均匀布置方案的3R2t倍,这里t为传感器节点的通信距离,R为传感器节点的分布区域半径.-Fusion-based Sensor Placement for Target Detection with Guaranteed Accuracy Abstract:In sensor networks,sensor nodes collect local data and transfer these data to the base station often relayed by other nodes.Therefore sensor nodes that are nearer to the base station will consume more energy. If deploying sensor nodes in general way, i.e. deploying nodes uniformly in the network, sensor nodes nearby the base station will use up energy soon and the base station can t collect data anymore. This paper presents a density function to deploy sensor nodes through investigating energy consumption in wireless sensor network. Theoretical analysis and simulation result show that deploying by method of this paper improve system lifetime to times of deploying uniformly, where t is radio distance of sensor node and R is radius of the region of deploying sensor nodes.

[Software Engineering] coleach_3 DL : 0: Energy efficiency is the most important design goal for wireless sensor networks (WSNs). In this paper, we propose an energy-efficient cooperative MIMO scheme, which combines energy-efficient LEACH (EE-LEACH) protocol and cooperative MIMO. We name it as EE-LEACH-MIMO scheme. EE-LEACH is an improved LEACH algorithm, in which the network is partitioned to sectors with equal angle for avoiding the distribution non-uniformity of cluster heads. In EE-LEACH-MIMO scheme, the location and the residual energy of each node are considered when the cluster heads for clustering and cooperative nodes for MIMO system are chosen. For comparisons, LEACH, EE-LEACH, the simple cooperative scheme with LEACH and MIMO (LEACHMIMO), and EE-LEACH-MIMO scheme are simulated. The result shows that EE-LEACH-MIMO scheme can well balance the network load, save energy and prolong the network lifetime

[Documents] A Tree Based Data Aggregation Scheme for Wireless Sensor Networks Using GA DL : 0: Energy is one of the most important items to determine the network lifetime due to low power energy nodes included in the network. Generally, data aggregation tree concept is used to find an energy efficient solution. However, even the best aggregation tree does not share the load of data packets to the transmitting nodes fairly while it is consuming the lowest possible energy of the network. Therefore, after some rounds, this problem causes to consume the whole energy of some heavily loaded nodes and hence results in with the death of the network. In this paper, by using the Genetic Algorithm (GA), we investigate the energy efficient data collecting spanning trees to find a suitable route which balances the data load throughout the network and thus balances the residual energy in the network in addition to consuming totally low power of the network. Using an algorithm which is able to balance the residual energy among the nodes can help the network to withstand more and consequently extend its own lifetime. In this work, we calculate all possible routes represented by the aggregation trees through the genetic algorithm. GA finds the optimum tree which is able to balance the data load and the energy in the network. Simulation results show that this balancing operation practically increases the network lifetime.
