In the low power wide area network, the LoRaWAN protocol adopts ALOHA type to access channel without duty cycle limited. The energy-efficient of the node and the robustness for varying traffic load are not considered in the situation which may lead to unfairness of node. To balance the energy consumption and network performance, an adaptive duty cycle medium access control (ADC-MAC) protocol is proposed...
In wireless sensor networks(WSNs), energy-efficiency and packet time delay are two major considerations in the design of medium access control(MAC) or routing algorithms. However, these two metrics always can't be satisfied at the same time, and existing works do not trade offthem well. In this paper, we first exploit a prediction model to evaluate the amount of packet in the next period. Then we...
In applications of Wireless Sensor Networks (WSNs), all data packets are directed towards a single base-station (BS) over multi-hop routes. The BS is usually responsible for processing the collected data and interfacing the WSN to remote users. The continuous flow of packets towards the BS enables the adversary to analyze the traffic and uncover the BS position. In this paper, we present a technique...
Optimized energy utilization in Underwater Wireless Sensor Networks (UWSNs) is a challenging task and an active research area. Non-uniform energy consumption in a sensor network creates coverage holes that mean nodes with no transmission energy. These holes degrade the performance and reduce lifetime of UWSNs. In this work, we propose an Optimized Depth Based Routing (ODBR) scheme which ensures uniform...
In this paper, we present a MAC protocol called Hop Extended Pipelined Routing MAC (HE-PRMAC) that enables a node to send a data packet for multiple hops in a single duty cycle similar to PR-MAC and has the ability to handle traffic overhead in an efficient way. HE-PRMAC addresses delivery latency and throughput degradation in wireless sensor networks (WSNs) using hop extended mechanism and a new...
Wireless sensor network (WSN) consists of sensor nodes to sense environmental or physical data and that will be communicated to sink through one hop or multi hop communication. These sensors are small, with limited processing and computing resources. These sensors can sense, measure, and gather information from the environment and transmit that data to the sink. All nodes in network are trying to...
The Internet of Things (IoT) expects to link billions of devices to the Internet, which will produce massive amounts of data. Current approaches move the IoT data out of the network for processing. It results in long delays and increases the network traffic. The Named Function Networking (NFN) proposes a generic computation architecture for in-network data processing. But it does not consider a scheduling...
This paper introduces a scheduled based Media Access Protocol for wireless sensor network termed RRS, an adaptive MAC protocol employing Improved Reinforcement Learning algorithm. Existing MAC protocol's work on scheduling the sleep-active cycle of wireless nodes transceivers in order to minimize the ideal energy consumption. More recent protocol employs adaptive duty cycle based on individual node's...
In this paper, we propose a new Medium Access Control (MAC) protocol for Wireless Sensor Networks (WSNs) called MMSMAC (Multi-Mode Sensor MAC protocol), which can operate and switch among three modes: synchronous, asynchronous, and hybrid, according to the application requirements. In the synchronous mode, MMSMAC organizes the sensor nodes under even and odd clusters. Each sensor node has its own...
A system having an embedded processor which can operate at minimum power with a small memory, where sensor having low data rate, battery, a GPS system and transceiver that operates at low data rate, collectively constitute a wireless device system. The power source in a wireless device system has a fixed value electro motive force (EMF) which is nothing but a battery. The EMF placed to any wireless...
Wireless sensor networks are resource constrained with less memory space, limited power supply, processing speed and availability of bandwidth for communication. Information gathering is the fundamental task of wireless sensor networks. However due to enormous deployment of sensors, a large amount of data is generated by these sensor networks. Processing and transportation of such a huge data increase...
Detectable Opportunistic Forwarding (DOF) is a duplicate free opportunistic forwarding protocol for low duty cycled wireless sensor network. DOF enables senders to obtain the information of all potential forwarders through acknowledgement scheme deliver the data packets to the next hop forwarder. Based on admission control algorithm using link stability the duplicate packets can be removed. The experimental...
The difference in transmission performance arises among child cluster heads (CCHs) on inter-cluster communications in cluster-based wireless sensor networks (WSNs) with spatial non-uniform traffic because several CCHs with different traffic loads communicate to their parent cluster head on shared communication channel. Against this problem this paper proposes traffic adaptive backoff control mechanism...
A significant number of previous studies have shown, however, network traffic exhibited frequently large bursty traffic possesses self-similar properties. For the future applications of wireless sensor networks (WSNs) with large number of cluster structures, such as Internet of Things (IoT) and smart grid, the network traffic should not be assumed as conventional Poisson process. We thus employ ON/OFF...
The energy consumption in Wireless Sensor Networks, WSN, need to be balanced in order to avoid early depletion of nodes. In this paper we use a common context to analyze a broad range of the energy balancing algorithms suggested in literature. In addition we suggest three new algorithms to complete the range. Altogether, nine different balancing techniques are analyzed. We focuses on networks running...
Wireless Sensor Network (WSN) is a promising technology for many applications, such as industrial, environment, and health-care application. The first requirement of WSN is energy efficiency in order to increase the network node lifetime. The second is reliability because packet drop cannot be tolerated in critical time applications. In this paper, we use NS2 simulation to evaluate and analyze the...
Wireless sensor networks (WSNs) have inspired many research domains in recent years. Congestion is a major issue faced by such networks, which causes heavy loss in data transmissions. Congestion is caused due to several reasons, such as heavy traffic, link failure, node failure and many more. There are various techniques developed for combatting network congestion. In this paper, we have proposed...
Quality of Service (QoS) provisioning in Wireless Sensor Networks (WSNs) presents an open research issue within the scientific community because the rapid development of microelectronics proliferates new applications for WSNs. These applications often require a connection of end-to-end delay and high reliability for various communication models. Within this scope, a special class of WSNs are query...
In this paper, we propose an Intrusion Detection System (IDS) against Sinkhole attack in wireless sensor networks with mobile sink. In the detection model, the network area is divided into a flat grid of cells, and we use the signature-based technique, which is represented by the detection rate of a cell, to distinguish between real and fake sink nodes. The proposed IDS considers two types of sink...
