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. To solve this drawback the conception of movable sink is presented. In this approach mobile sink gather the inform the static sensors of the network and transfer it to base station. For efficiently gather the data sink's mobility pattern should be...
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...
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,...
The Wireless sensor network (WSN) is a type of the wireless ad-hoc networks. It consisting of a large number of sensors is effective for gathering data in a variety of environments. Since the sensors operate on battery of limited power, it is a great challenging aim to design an energy efficient routing protocol, which can minimize the delay while offering high-energy efficiency and long span of network...
SPEED routing algorithm is a service quality based algorithm in which data aggregation dose not happen. In this article, data aggregation has been added to the conventional technique in SPEED algorithm. The idea involves virtual configuration of sensors and specification of an individual ID to the created data by the sensors in each region, then data aggregation in relay node is done by this ID, resulting...
How to make full use of the limited energy available and prolonging the survival time of node is a major concern in research on wireless sensor networks (WSNs). This paper presented an improved approach based on directed diffusion protocol (DDP) which could meet the features of WSN, such as data-oriented, many-to-one transmissions and low energy costs, together with data aggregation mechanisms which...
Sensor networks pledge to solve many monitoring problems: thousands of small inexpensive devices can be easily deployed in any environment and can provide measurements about diverse phenomenons, such as temperature, pollution, birds migration, etc. As sensors are low-capabilities, battery powered devices, several protocols have been proposed to maximize their lifetime, but only recently research has...
