The wireless sensor networks (WSNs) is one of the developing and rapidly increasing field in the modern world. Due to this challenging task is to develop multi-function, low cost and low-power sensors. In WSNs, large number of sensor nodes within the cluster sensed the environment and send data to the cluster head. This paper contain new energy efficient clustering algorithm which is used for effectively...
Applicability of Wireless Sensor Networks is found in fields manifold. Energy issues proved to be a continuous setback to the performance of these networks. Data aggregation and the use of local base stations is seen as a promising solution to the problem. Clustering is a simple technique to achieve this. The local base stations or the cluster heads aggregate data from nearby nodes, process it and...
Internet of Things (IoT) is a new paradigm which is enormously gaining ground in today's world. In order to maintain desirable service quality in the transmission of sensed data, data aggregation schemes are highly used. The main goal of data aggregation scheme is to collect and aggregate data packets in an efficient manner so as to reduce power consumption, traffic congestion, and to increase network...
In wireless sensor networks data gathering is very important task. Nowadays analysis has been targeted on decreasing the energy consumption of the WSN.

Data aggregation is known as the collection of data from a set of sensors toward a sink node with routing algorithms. For that, many structured protocols used for aggregation and forwarding packets. Since, sensor nodes are less battery powered devices, its maximum energy spent for constructing certain topologies. There are number of prior works based on tree-based or cluster-based, grid based and...
A synchronized network time is always necessary for scheduling to achieve energy efficiency, data fusion, localization for WSN applications. The major limitation in a WSN is the battery usage and lifetime of the nodes. Due to the power restriction of nodes, efficient routing is very important to save the battery of sensors to enhance the lifetime of the sensor area. The multi-head chain concept is...
Wireless sensor networks consist of small battery powered devices with limited energy resources. The small sensor nodes are usually inaccessible to the users due to their remote deployment. Non functioning of any sensor due to its loss of battery power not only deteriorates the network performance but also a challenging job for replacement of energy source. Hence, energy efficiency is a key design...
In one hand, sensor nodes consume low energy when they communicate with TDMA protocol, by eliminating collisions and idle listening. On the other hand, data aggregation algorithms are used to gather and aggregate data in an energy efficient manner so that network lifetime is enhanced. TDMA protocols are more power efficient since nodes in the network can enter inactive state until slot times will...
Wireless sensor network consists of micro electro-mechanical sensor nodes which are operated by battery power. Sensor nodes lose energy for computation and communication. It is very difficult to recharge their battery as they are deployed in a remote place. Thus, power efficient routing in wireless sensor network is the main challenge for researchers. Hierarchical routing is one of the efficient techniques...
One of the major issues in Wireless Sensor Network is maximizing the lifetime of the network. In general, all sensor nodes directly send the information to the Base station so the energy requirement is very high. Clustering is used to decrease energy consumption and collision. In this paper, we propose an Energy efficient Cluster Based Data Aggregation scheme for sensor networks (ECBDA). This scheme...
Recently, many researchers address on the problem of reducing power consumption for data aggregation in wireless sensor networks. However, many existing event-to-sink routing schemes for data aggregation require assistance from a global positioning system (GPS), which is not always available. In this paper, we propose a GPS-free event-to-sink routing scheme for data aggregation in wireless sensor...
A typical wireless sensor network (WSN) comprises a large number of wireless sensor nodes. This large number of wireless sensor nodes provides a network with redundant sensing power. By utilizing an energy-aware on-off scheduling scheme, some of the nodes can be switched off adaptively without affecting the sensing performance of a network. However, such kind of scheduling schemes will also break...
In VANETs, security is of prime concern. A successful attack by an adversary might have disastrous effects leading to loss of life. At times an adversary may perform event modification, false event generation, data aggregation and data dropping. To overcome these we present a robust algorithm VSRP (Vehicular Security through Reputation and Plausibility checks) to employ security in VANETs. The algorithm...

In this paper, we refine slot allocation to the nodes in dynamic convey tree and design an energy efficient MAC protocol called D-TDMA, which avoids collisions and interferences and allocates contiguous...
In some applications of WSN, each node can communicate with the base station, if each node communicates with base station directly, there are will a lot of duplication of information and cause waste of nodes' energy. For this reason, we put forward Data Query Protocol Based on Minimum Spanning Tree (QPMST) , QPMST protocol can create a minimum spanning tree with sink as root and other nodes as descendants,...

Energy efficiency is the most important issue in wireless sensor networks. To reduce energy consumption, lots of aggregation algorithms were proposed.
