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...
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...
Wireless Sensor Network is the set of homogeneous or heterogeneous sensor nodes; those can sense the data from different sensing areas of the network. There are different routing protocols exist for find the efficient route to transmits the data from source to destination. The performance of the routing protocols depends of the various factors in the network like packets size, types of signals, movement...
Wireless Sensor Networks (WSNs) consists of a large number of low-power, limited-processing and limited-storage sensors, which is applied for all kinds of areas. In the paper, we introduce an energy efficiency trusted dynamic routing protocol for wireless sensor network (EETDRP), which is designed based on Destination Sequenced Distance Vector Protocol and trusted management. And the wireless sensor...
The field of Wireless Sensor Networks (WSN) is undergoing a major revolution, opening the prospect of significant impact in many application areas (safety, health, environment, food safety, manufacturing, telecommunications. Routing isfundamental such a network because there is no infrastructure that manages the information exchanged between network nodes. Two major classes of routing algorithms are...
Focusing on the issues of security and energy efficiency, we present an energy-efficient secure routing protocol for wireless sensor networks (WSNs). With the location and energy-aware characteristics for routing, our protocol gives a better delivery rate, energy balancing, and routing efficiency. In addition, the proposed security mechanism ensures the data authenticity and confidentiality in the...
Wireless sensors have the capacity to gather information like temperature, sound, motion or pollutants, being distribute in an environment that has to be monitored and controlled for many domains like industry, healthcare or military applications. Grouped in networks with one Base Station gathering the useful data, the sensors are characterized by limited battery life and low processing power, which...
Although free space optical sensor networks (FSOSNs) show merits of larger capacity, higher security and lower energy consumption over conventional radio- frequency (RF) based sensor networks, the directionality of free space optical (FSO) links requires efficient routing protocol for data transmission, because the death of a node may cause a dramatic decrease of network connectivity, resulting in...
Wireless Sensor Networks (WSNs) has very foremost role with all sensing applications, and also have a wide range of easily deployable applications under any circumstances. That's why it is gaining more attention of researchers every day. WSN is resource constraint type of network, without having battery recharging facility. Routing or path finding for data transfer is the main energy consuming operation...
The link quality based Collection Tree Protocol (CTP) has been demonstrated an efficient and reliable routing protocol for data collection networks that deploy a clustered tree topology. However, CTP measures the link quality by packet throughput rather than transmission latency, which is not appropriate for networks supporting sensor events with transmission time deadlines. In this paper, we propose...
Wireless communication devices are widely subjected to intruder attacks and in the existing security system, the algorithm consists of a ranging phase that uses the received signal strength to estimate a network radio map and a localization phase which uses a genetic algorithm to obtain the most likely position of the intruder node within the map using the genetic algorithm which is not time consuming...
The ROLL working group at IETF is currently designing RPL, the Routing Protocol for Low power and lossy networks. RPL is based on organizing the nodes in a network in one or more directed acyclic graphs(DAGs) rooted at the popular/default destinations. The DAG structure naturally supports multipoint-to-point routing towards the DAG root and point-to-multipoint routing from the root towards the nodes...
A geographical forwarding algorithm is an attractive localized data forwarding scheme for wireless sensor networks (WSNs) due to its directional routing properties and scalability. Also, the inherent constraints of WSNs such as limited battery power and network resources require the simplicity and energy efficiency of protocols. In this paper, we propose a Time Backoff-based energy-efficient Geographical...
Sensor networks are a sensing, computing and communication infrastructure that are able to observe and respond to phenomena in the natural environment and in our physical and cyber infrastructure. The sensors themselves can range from small passive micro-sensors to larger scale, controllable weather-sensing platforms. In order to simulate Wireless Sensor Networks (WSNs), we implemented a simulation...
Wireless Sensor Networks (WSN) need to be organized in order to be more resource-efficient and scalable. Directed Acyclic Graphs (DAG) are of interest for WSN organization because of their route redundancy to the root. A recent routing protocol for WSNs coming from the IETF ROLL Working Group specifies the use of DAGs and proposes to improve the route redundancy even further by routing through sibling...
Low-latency data delivery is an important requirement for achieving effective monitoring through wireless sensor networks. When sensor nodes employ duty cycling, sending a message along the shortest path, however, does not necessarily result in minimum delay. In this paper, we first study the lowest latency path problem, i.e., the characteristics of a path with minimum delay that connects a source...
Recently, Wireless Sensor Networks (WSNs) which consist of thousands of sensor nodes have become one of the most popular topics. Different from the common Ad-hoc networks, energy efficient routing protocol is the most important issue in WSNs. LEPS (Link Estimation and Parent Selection) is the routing protocol used in the TinyOS, which is widely used in many kinds of WSNs platforms. But in LEPS protocol,...
In most of existing routing protocols of wireless sensor networks (WSNs), a route is set up through broadcasting the route request (RREQ) messages throughout the entire network, which often brings broadcast storm. In this paper, we propose a new gradient-based micro sensor routing protocol (GMSRP) to alleviate the broadcast storm. With the GMSRP, during the network initialization, the sink node broadcasts...
Flooding is often used by routing protocol to establish a routing tree. However, the effect of backoff mechanism on routing tree topology is ignored by most of researchers on designing their routing protocols. In addition, the collision is much more fiercely in a flooding procedure. In this paper, the influence of backoff mechanism on establishing routing tree topology and the message collision in...
