It has been found that almost all routing protocols can induce network congestion due to control message complexity. To overcome this overhead various optimization processes are used. One such process is gossiping, where each node forwards a message with some probability, to reduce the overhead of the routing protocols. In this paper, we show how gossiping can be used to improve the performance of...
The field of wireless sensor networks is progressing at a very rapid pace with one of its major application in the area of agriculture. Several research problems have been addressed and solutions have been proposed. Most of these works are based on single crop scenario. Research done in the multiple-cropping scenario, where two or more crops are sown in a single field in the same year, are very few...
Now a days usage of Wireless Sensor Networks (WSNs) is increasing, because of its wide application. Unlike common networks the WSNs have the capability of reconfiguration, whenever any defect occurs in the network. However, while routing in these network the loss of data is occurring due to its security lack. Hence many researchers have presented their research for providing secure routing in WSNs...
A heterogeneous ring domain communication topology with equal area in each ring is presented in this paper in an effort to solve the energy balance problem in original IPv6 routing protocol for low power and lossy networks (RPL). A new clustering algorithm and event-driven cluster head rotation mechanism are also proposed based on this topology. The clustering information announcement message and...
Spontaneous progress in the field of wireless sensor networks (WSN) have led to development of various protocols for reliable communication and increasing longevity of the network. While designing the protocols for WSNs, designers come across the issues like limited energy per node, limited bandwidth for communication, security, minimum communication and computational cost. This paper focuses on energy...

Effective strategies are required to ensure efficient data collection for wireless sensor networks deployed in harsh environment, and where propagation conditions are unstable. In this paper, we propose a scheduled based routing protocol that use both topological and link quality information to adapt to environment changes. The multiples channels is used to enable parallel transmissions and hence...
Wireless sensor networks collecting data to monitor real life processes gain increasing attention from the scientific community. These systems promise ubiquitous computing in a digitalized world. However many problems need to be solved to achieve this dream. One of these problems is the limited battery power of the nodes and the limited bandwidth of the communication. Existing work tackle the problem...
Paper describes a concentric circular wireless sensor network topology and sensor data retrieving strategy using a mobile sink. A quadcopter acts as a mobile sink. The strategy states how to improve network lifetime by reducing energy consumption of power constrained sensor nodes. It eliminates packet routing and optimizes packet retransmissions by reducing packet error, packet loss and packet collisions...
Wireless Sensor Network (WSN) is an ad-hoc network consisting of sensor nodes having limited computational power fitted with a radio transceiver. Main constraint of a sensor node is the limitation of its energy resource in the form of a short battery life. Battery power conservation is very important in a sensor device since battery life is usually one of the critical componets in extending the life...
In this paper, we explore methods to generate optimal network topologies for wireless sensor networks (WSNs) with and without obstacles. Specifically, we investigate a dense network with n sensor nodes and m=n^b (0<b<1) helping nodes, and assess the impact of topology on its throu\-gh\-put capacity. For networks without obstacles, we find that uniformly distributed sensor nodes and regularly...
Wireless sensor networks (WSNs) consist of tiny sensor nodes with sensing, computation and wireless communication capabilities. As sensor nodes are resource constrained, the usage of energy and memory must be done wisely to increase the lifetime of nodes. It is also necessary to deliver data reliably to make any application more useful to the end user. In this paper we propose a protocol using cluster...
In this paper, we introduce a novel least distance smart neighboring search (LDSNS) to determine the mostefficient path at one-hop distance over WSNs. LDSNS helps to reduce the energy consumption and speeds up scheduling for delivery of data. It provides cross layering support and linking MAC layer with network layer to reduce the amount of control messages. LDSNS is a robust and efficient approach...
Compared with wired networks, ZigBee wireless sensor network (WSN) can not directly view the deployment of each device in the network, and observe the topology of the network, therefore bring inconvenience to the network administrator. To solve this problem, it needs to provide an intuitive visualization of the network topology. ZigBee WSN is based on this topology algorithm networking, and topology...
We consider the design and implementation of the binary consensus algorithm in wireless sensor networks (WSN) under real life environment. This algorithm is applied for the evaluation of a consensus of a measured values in presence of a faulty/attacked node. As this algorithm has been tested theoretically, we deploy it for real-life environment including distributed and routing features. In this paper,...
It is well-known that in wireless sensor networks using minimum-energy paths to transfer data from sensor nodes to base station is not an energy-balancing option and not the optimal solution if lifetime, defined as the duration till the first node in the network exhausts all its energy, is of concern. However, the net effect of minimum-energy routing on network lifetime has not been studied in detail...

In this paper, we have proposed a framework for forest fire detection and monitoring as an application area of wireless sensor networks. Our systems...
Distributed Address Assignment Mechanism (DAAM) has been suggested to be used in the ZigBee tree topology for its simplicity and efficiency. However, its topological parameter restricts the shape and extent of the networks, and results in orphan problem and poor coverage. Three alternatives are proposed and evaluated in this article. 2-layer DAAM (2DAAM) uses hierarchical scheme, which divides the...

Geo-Logical Routing (GLR) is a novel technique that brings the advantages of geographic routing to logical domain, without inheriting the disadvantages of physical domain, to achieve higher routability at a lower cost. It uses topology domain coordinates, derived solely from virtual coordinates (VCs), a better alternative for location information. In logical domain, a node is characterized by a VC...
