In Wireless Sensor Networks (WSNs), sensor nodes depend on batteries for energy source. The ability to use limited energy efficiently is the key to determining the lifetime of networks and the amount of information transmitted. Low Energy Adaptive Clustering Hierarchy (LEACH) is a representative cluster-based routing protocol designed to ensure energy use efficiency. In this paper, a protocol scheme...
Wireless sensor network consists of numerous small and low cost sensors which collect and transmit environmental data. These nodes are spatially distributed and capable of measuring their ambient. Sensor node is responsible for collecting data in regular intervals, converting the obtained data into electronic signals and transmitting data to sink node or base station through reliable wireless communications...
The main challenge facing us in the design and conception of Wireless Sensor Networks (WSNs)is to find the best way to extend their life span. The clustering algorithm is a key technique used to increase the scalability and life span of the network in general. In this paper, we have proposed an energy aware cluster head selection algorithm, for heterogeneous wireless sensor networks, by modifying...
The use of Wireless Sensor Networks (WSN) is anticipated to bring lot of changes in data gathering, processing and dissemination for different environments and applications. Energy consumption is the most crucial design issue in WSN. In order to solve the issue and prolong the network lifetime, energy resources of each node in WSN need to be effectively managed. With respect to energy efficiency,...
In designing of the routing protocols for Wireless Sensor Networks, clustering is one of the methods used to manage network energy consumption efficiently. LEACH is one of the most famous clustering mechanisms. It elects a cluster head based on probability model. In LEACH, within each 1/p rounds, once a node has been selected as a cluster-head (CH), its threshold will be set to 0, and thus it will...
Considering extremely limited energy of sensor nodes, how to utilize energy of the sensor nodes effectively to prolong survival time of wireless sensor network (WSN) is crucial. Aiming at monitoring application in particular regions, residual energy and distance constraint condition between cluster heads are taken into consideration. A new wireless sensor network clustering algorithm (EDL, Energy...
In recent years, many clustering algorithms have been proposed. Among them, LEACH is the most famous one. However, in LEACH, within each 1/p rounds, once a node has been selected as a cluster-head (CH), its threshold will be set to 0, and thus it will lose the chance to participate cluster-head selection, even if it still has enough energy. In this paper, we present a novel cluster-head selection...
For wireless sensor networks (WSNs), it is a challenging task how to schedule the energy resource to extend the network lifetime due to the fact that WSNs are usually powered by limited and non-rechargeable battery. A clustering scheme is helpful in reducing the energy consumption by aggregating data at intermediate sensor nodes. In this paper, we propose a balanced parallel k-means based clustering...
In recent years, the wireless sensor network (WSN), which has a good application prospect in both civil and military fields, has received increasing attention. But due to the particularity of the WSN, the traditional network routing protocol is not suitable to it. There is a great need for new routing protocols for the WSN. For WSN, the network node energy is usually limited, so how to save and even...
