RPL is an IPv6 routing protocol for low-power and lossy networks (LLNs) designed to meet the requirements of a wide range of LLN applications including smart grid AMIs, industrial and environmental monitoring, and wireless sensor networks. RPL allows bi-directional end-to-end IPv6 communication on resource constrained LLN devices, leading to the concept of the Internet of Things (IoT) with thousands...
There has been a decade of extensive research on application specific wireless sensor networks (WSNs). The recent development in communication network technologies makes it practical to realize a new WSN paradigm or controlling the control plane with the new group of by software defined networking (SDN) based on Open Flow. The Open Flow technology which is known for standardization and compatibility...
Based on the non-uniform Node distribution of multi-hop routing in wireless sensor networks, which makes the energy hole premature and eventually caused the end of network survival period problem, the author summarized the research status of wireless sensor networks and proposed routing optimal algorithm which is based on the LEACH protocol. In reference to LEACH routing algorithm and based on the...
A sensible and foresighted planned routing protocol has a vital role to add life to the sensor network. Concentrated and iterative path routing, unbalanced load emphasizing, non-scalability property and frequent beacon exchange squeezes the life of stringent energy constraint Wireless Sensor Network. WSN is a special type of Adhoc network with energy, memory and processing constraint factors for sensing...
In this paper, we proposes a multi-gateway nodes data collected routing algorithm based on load balancing(TBLB algorithm) and energy balance, robustness, data forwarding and anti-interference etc, which is multi-gateway nodes-based in wireless sensor network. This algorithm fully takes into account the problem of excessive power consumption when it serves as the data forwarding task, to reduce node...
We consider the online data gathering problem in wireless sensor networks and examine the key issues of load balancing the nodes to achieve longer network lifetime, and that of load balancing the network links to achieve greater reliability in the network. We model the given network as a shortest-path DAG D, which defines a set of parent nodes for each node that determine the minimum-hops paths from...
The wireless sensor network is an autonomous collection of sensors which makes a simple, high speed and inexpensive network. These kinds of network are able to monitor a parameter where the coverage is impossible via wired networks. Since, the sensors in wireless networks are equipped with batteries, these networks are energy constrained and clustering approaches play an important role in energy efficiency...
We propose a new location-based stochastic routing approach that is well-suited for wireless sensor networks deployed for public safety applications such as emergency evacuations or search and rescue operations. We first introduce a new modeling and evaluation framework based on Markov chains for randomized routing. Based on this evaluation framework, we study the load balancing and routing performance...
The resource-constrained nodes in wireless sensor networks (WSNs) are prone to failures, especially due to battery depletion. Well-defined effective metrics to identify the potential vulnerability in advance are essential for failure prevention. We propose a novel and advantageous metric called Battery Index to predict energy-vulnerable nodes at the very early stage of the network lifetime. Enabled...
Directed diffusion is a data-centric routing protocol used in wireless sensor networks and uses only local interaction between neighbor nodes. One of the problems of this approach is the mechanism used for routing selection which mostly, leads to select the shortest path between sinks and sources. In this case the nodes in the shortest path will fail after a short period of time due to lack of energy...
Recently, the focus of sensor network paradigm is changing for delivering multimedia contents such as audio and video streams and still images. However, most existing routing protocols are not very practical for transmitting multimedia contents in resource constrained sensor networks. In this paper, we propose an optimized nod-disjoint multi-path routing scheme resulting in throughput enhancement...
Designing a sensor network congestion avoidance algorithm is a challenging task due to the application specific nature of these networks. The frequency of event sensing is a deciding factor in the occurence of congestion. Numerous sensors, simultaneously transmitting data, increase the probability of packet drops due to congestion close to the base station(s). In this paper, we propose a novel distributed...
Environmental conditions, energy, bandwidth, storage and processing constraints, application and wireless sensor network, especially in real-time usage faces serious challenges. Thus, providing methods for reliable data transmission at desirable rate which takes into consideration energy constraint is of great importance. In this paper, a routing metric is introduced for selection of intermediate...
As wireless sensor networks (WSNs) increasingly attract more attention, new ideas for specific applications are continually being developed, many of which involve the energy consumption of nodes. However, not much has been done to optimize the quality of services (QoS) of WSNs. Many applications like target tracking require some QoS guarantees. Besides, certain factors limit the ability of multi-hop...
In this paper, we propose a novel routing algorithm for maritime monitoring of short term events where large area monitoring relies on small buoys drifting along with local currents. The objective of this algorithm is to improve communication where scalable mobile networks are optimized by taking into consideration a weight function based on remaining energy and relative distance between buoys. To...
