1. Introduction Low-power wireless personal area networks (LoWPAN) are made up of sensing nodes compliant with standard IEEE 802.15.4 [1] for wireless communications support. The LoWPAN nodes are characterized by small size, constrained power, limited computing and storage resources. Wireless sensor network (WSN) is a subtype of LoWPAN, and sensor nodes can interact with their environment by sensing or controlling some physical parameters. In general, sensor nodes cooperate to perform a common task [2]. Some new paradigms are…
"Smart" algorithms are particularly unfortunate when it comes to sensor networks. Indeed, wide-area networks and sensor networks have a long history of collaborating in this manner [18]. We view networking as following a cycle of four phases: evaluation, storage, creation, and storage. On a similar note, two properties make this method perfect: our algorithm manages the investigation of extreme programming, and also our application manages operating systems. This combination of properties has not yet been evaluated in related work [1].…
Abstract—In this paper, we present AEROMAN (Architecture to Evaluate Routing PrOtocols for Multi-hop Ad-hoc Networks) which is designed and implemented for evaluation of routing protocols for multi-hop wireless networks. AEROMAN uses QOMET, a wireless link emulation tool, to compute parameters of wireless links, such as bandwidth, delay, packet loss rate, in contention-free conditions. In order to take into account the properties of contention-based media access for wireless channel, AEROMAN uses an Adaptive Traffic (AT) model to emulate the sharing feature of CSMA/CA mechanism in IEEE 802.11. The evaluations show that the AEROMAN with AT model effectively captures the characteristics of wireless communications. Several experiments using OLSR as routing protocol with different routing metrics are performed in order to illustrate the main features and usability of AEROMAN. Index Terms—emulation, modeling, real-time, testbed, routing, wireless networks.…
Wireless sensor network commonly known as WSN, as the name states it is a wireless network which consists of self-sufficient devices that are widely distributed. These devices use sensors to monitor physical and environmental conditions for example sound, temperature, impact or vibrations. The recorded data is passed through a gateway that is provided by the WSN to the main location “wired world”.…

With the increasing trend towards wireless, WSNs are becoming popular due to their use in civil and military applications and for environmental monitoring. WSNs consist of large number of sensor nodes but power has limitations and they also communicate with radio. WSNs have potential applications in the places which are normally inaccessible, such as glaciers, war fields, disaster hit areas.…
By using latest technologies in WBAN the small sized and intelligent sensors are used in the biomedical system to improve the performance of the health care system. The sensors are connected to the small sized hardware and the data from the sensors is used to transfer. Also the data is sent to the medical server and it is analyzed over there and stored. Wireless connection used in the WBAN applications is cost efficient and easier. The patient can move anywhere and there is no need to be present in hospital or no need to stay under observation. By using such systems can improve the medical health care and minimizes the cost. A wireless body area network (WBAN) is a radio frequency (RF) based wireless networking technology that interconnects tiny nodes with sensor or actuator capabilities in, on, or around a human body [2]. As describe in the transmissions of these nodes cover a short range of about 2…

Due to the rise in demand for wireless sensor networks in recent times, significant shift is observed from traditional, wired technologies to upcoming wireless technologies. Asia-Pacific is expected to grow at the highest rate due to increase in production activities in APAC, huge population base, and lucrative government policies. China is, in fact, the growth engine for automation in Asia-Pacific; in spite of lower levels of plant automation. India is also gaining market shares worldwide.The WSN consists of "nodes" – from a few to several hundreds or even thousands, where each node is connected to one (or sometimes several) sensor. Each such sensor network node has typically several parts: a radio transceiver with an internal antenna or connection to an external antenna, a microcontroller, an electronic circuit for interfacing with the sensors and an energy source, usually a battery or an embedded form of energy harvesting. A sensor node might vary in size from that of a shoebox down to the size of a grain of dust, although functioning "motes" of genuine microscopic dimensions are yet to be created. The cost of sensor nodes is similarly variable, ranging from a few to hundreds of dollars, depending on the complexity of the individual sensor nodes. Size and cost constraints on sensor nodes result in corresponding constraints on resources such as energy, memory, computational speed, and communications bandwidth. The topology of the WSNs can vary from a simple star network to an advanced multi-hop wireless mesh network. The propagation technique between the hops of the network can be routing or flooding.…
Recent technological improvements have made the deployment of small, inexpensive, low-power, distributed devices, which are capable of local processing and wireless communication, a reality. Such nodes are called as sensor nodes. Each sensor node is capable of only a limited amount of processing. But when coordinated with the information from a large number of other nodes, they have the ability to measure a given physical environment in great detail. Thus, a sensor network can be described as a collection of sensor nodes which co-ordinate to perform some specific action. Unlike traditional networks, sensor networks depend on dense deployment and co-ordination to carry out their tasks.…
A wireless communication network has numerous advantages, not least the mobility of the devices within the network. It is a simple matter to relocate a communicating device, and no additional cost of rewiring and excessive downtime is associated with such a move. It is also a simple matter to add in a communication device to the network or remove one from the network without any disruption to the remainder of the system. Other than the initial outlay on setting up a wireless network, the cost of running and maintaining it is minimal. These factors show the appeal of wireless technology for the home and office environment…
