In this paper, an efficient routing protocol for patient monitoring system in rural areas was proposed using wireless sensor network (WSN) so that the patients can be treated within less time. In this system, a village with GSM network is considered and the people in that village are continuously monitored using AMON sensor, an advanced medical monitoring and alert system. All the AMON's work in ADHOC...
A Mobile Ad Hoc Network (MANET) is a group of wireless mobile nodes which dynamically form a network without any established infrastructure. The application is considered in an agro-based project and therefore, Routing protocols are mandatory to send and receive packets. In this paper, we have evaluated the most commonly used routing protocols in MANET and compared the performance of reactive routing...
Wireless Sensor Communication Networks have more concern on its routing techniques. Since the WSCNs nodes are battery powered, routing algorithms should assure the concept of energy saving without affecting the other performance metric like Throughput, Delay and Packet delivery ratio etc. The modified AOMDV called as Enhanced Energy Efficient Multipath Routing Protocol ( EEEMRP )is a proposed algorithm...
This paper focuses on the comparative analysis of routing protocols such as Ad-hoc On-demand Distance Vector Routing System (AODV), Dynamic Source Routing (DSR) and Optimized Link State Routing (OLSR). The analysis is been made against different network parameters like network load, end to end delay and throughput in a small scale Wireless Local Area (WLAN) based Wireless Sensor Network (WSN) scenarios...
The wireless sensor networks have accomplished advancement in various applications such as military, smart homes, patient monitoring, and intelligent building. In this paper, the smart home proposed system has been presented basis on two types of sensor. As well as the evaluation comparison among Destination Sequenced Distance Vector with Ad hoc On Demand Distance Vector has discussed to determine...
Industrial application of wireless sensor networks require timelines in exchanging messages among nodes. IEEE 802.15.4 is a standard to address the need for low-rate low-power low-cost wireless networking. In wired connection, the components such as actuators or sensors provides high performance besides wired links consist of many mechanical problems. Hence to achieve low latency, high performance...
A MANET is a infrastructure-less and auto configurable network of mobile nodes which are connected without wires. As per proposal of this paper, the communication in a MANET works on set of random keys called KEY1=X+KEY0, KEY2=X+KEY1, KEY3=X+KEY2…KEYN=X+KEYN−1 to establish the connection between nodes and applies to validate the packets. Since there could be a issue of keys length, hence we can enforce...
The capability of Wireless Sensor Network to provide real-time monitoring and prediction of events has enabled its use in designing networks for safety critical applications such as Landslide Detection and Monitoring. To prolong the network lifetime, an energy aware clustering approach is necessary. However in a centralized clustering mechanism, the sink node performs the necessary computations of...
In wireless sensor network (WSN), data collecting from the environment and sending that data to be processed and evaluated is the most important issues. Hence performance evaluation and comparison between routing protocols is required because performance of any routing protocol can be changed or very with various parameters such as speed, seed time, pause time, number of node, and traffic scenario...
Wireless Sensor Network (WSN) is a group of spatially distributed sensor nodes and is self organized and autonomous in nature. They are connected by wireless links. Routing in wireless sensor network is quite different from traditional wireless network, due to limitations of wireless sensor network. To overcome some of the limitations, UDP is being used for connection establishment, compromising the...
In Wireless Sensor Networks (WSNs), fair utilisation of the network resources is a challenging task. In this regard, one of the determining factors is the routing protocol that plays an important role to route the data traffic from the source to the destination, under limited network resources. Most of the routing protocols and their variants in WSNs replace the routing metric of the prevalent routing...
In wireless sensor and actuator networks (WSANs), whenever an event occurs in the physical world, sensors gather this information and forward it to actuators which are responsible for taking prompt decisions and react accordingly. To ensure an efficient action, an any cast routing mechanism is trivial, a sensor node wishes to report event information to any actuators in the network and one of them...
Wireless sensor network (WSN) has diverse field of applications, but on the other hand it is very much prone to the various security threats. There are number of attacks on wireless sensor networks like black hole attack, selective forwarding attacks, sink hole attack sybil attack etc. This paper concentrates on the performance of wireless sensor network in the presence of black hole attackers using...
Wireless Sensor Networks (WSNs) have emerged as a new class of large scale networks of embedded systems with limited communication, computation and energy resources. Recently IEEE 802.15.4 standards are accepted as Low-Rate Wireless Personal Area Network (LR-WPAN) which are most extensively used communication platform for WSNs. Traditional routing in IEEE 802.15.4 networks is based on Ad hoc On-demand...
In Wireless Sensor Network (WSNs), routing protocol is an important aspect to utilize network resources fairly. Normally, routing mechanisms are selfish in nature and are based on a single objective criterion, e.g., hop count. This behaviour is inappropriate for a long lasting communication as it causes performance degradation in the entire network and ultimately leads to network congestion. To enhance...
